the discovery of sinopec shengli oilfield can be traced back to the first industrial oil flow well "hua 8 well" drilled by the older generation of oil workers in 1961. over the past 60 years, from the large-scale oil exploration and development campaign in north china to the more than 20 leading oil and gas exploration and development technologies at home and abroad formed by the shengli oilfield exploration and development research institute, from china's first "thousand-ton well" to the qingdong 5 beach offshore and onshore oil production platform with a cumulative oil production of one million tons, an "old" oilfield is still constantly "innovating".
by the end of 2023, shengli oilfield has achieved more than 8,000 scientific and technological achievements, 122 national science and technology awards, and 7,195 national patents. moreover, on the journey from "victory" to the next "victory", people here not only use technology to find oil, but also integrate the concept of green development into the development of the enterprise.
“old” oil fields gain “new vitality”
born after 1985, zhang zilin has become the youngest technical chief in the shale oil fracturing innovation team of shengli oilfield petroleum engineering and technology research institute. he is responsible for the research of full three-dimensional simulation technology of shale oil fracturing and the optimization test of pilot test wells.
"shale oil is like a thousand-layer cake," zhang zilin described. "oil and gas are the butter and powdered sugar sandwiched between the cookies." his job is to use fracturing technology to "break up" the rock formations and then reconstruct artificial channels to extract the oil and gas.
in order to break through the difficulties, zhang zilin and his colleagues innovated shale oil fracturing simulation technology and developed a simulator. during the research process, it is necessary to continuously program and digest new experimental data. in the process of promoting innovation, we must make full use of the achievements of predecessors and continuously promote technological innovation based on the predecessors.
"only if we workers are innovative can we achieve more." in feng xinyong's innovation work exhibition room, a display board on mechanisms driving innovation is very conspicuous. what they are most concerned about is how to solve technical problems in the front-line production process.
shengli oilfield has formed a nine-step closed-loop innovation work mechanism of "collecting problems, reviewing and approving projects, posting bids, appointing leaders, innovative research, financial support, expert guidance, acceptance evaluation, and transformation and promotion", transforming production problems into productive forces that drive development.
turn ideas into practice, and turn "ideas" into "gold". the oil production plant conducts a problem collection activity for all employees in the plant every year, using the method of "front-line employees setting questions, business departments pointing out questions, and leaders at all levels setting questions" to collect front-line production problems, organize experts to check the collected front-line production problems, and select valuable problems as plant-level topics for project establishment. after the processes of posting bidding, unveiling the list and taking charge, and innovative research, innovative achievements with promotion value are transformed and promoted to enable high-quality development with innovation.
"bottleneck" technical difficulties are the "bottleneck" of high-quality development.
as an experienced technician who has been working on the front line for 37 years, feng xinyong has independently completed 139 innovative achievements and obtained 10 national invention patents and 59 utility model patents.
in shengli oilfield, there are more than 7,000 vertical belt pumping units. this type of pumping unit is popular for its long stroke, slow stroke, energy saving and high efficiency, but the displacement of the pumping unit has always been a problem. traditional operations rely on four people to pull the guide chain, which only moves more than 20 centimeters per hour; using special vehicles to pull the device can easily lead to inaccurate displacement of the pumping unit and even cause oil leakage at the wellhead. the new vertical belt pumping unit displacement device developed by feng xinyong and his team has completely changed this situation.
"this device is equivalent to installing a 'steering wheel' on the oil pump," he explained. now, even two female workers can move the more than 10-ton oil pump smoothly and accurately by just turning a wrench.
“old” oil fields take on a “new” look
the sea is the main battlefield for shengli oilfield to increase reserves and production, and it is also the top priority for safety and environmental protection.
to achieve green development, the chengdao center no. 1 platform of shengli offshore oilfield (hereinafter referred to as "platform no. 1") has always adhered to the environmental protection concept of "no oil entering the sea, no water being discharged, and no gas going into the sky".
in the early production of platform no. 1, natural gas turbines were used to generate electricity for its own power supply. however, this power supply method had problems such as low basic efficiency and high voc (volatile organic compound) emissions.
in order to reduce energy consumption and achieve green production, in recent years, the no. 1 platform has begun to use shore power in an all-round way, supplying electricity through submarine cables. compared with traditional power supply methods, shore power has the advantages of high power generation efficiency, less environmental pollution and low economic cost.
"wherever there are oil and gas production equipment and facilities, there will be oil booms. if there is leakage under extreme circumstances, we will make sure the oil falls on the deck and never into the sea," said kong jian, director of platform management in the sea area management zone. on platform no. 1, all the oil booms are closed without any gaps, "not allowing a single drop of oil to flow into the sea."
when it rains, in order to prevent rainwater from washing away the equipment and flowing into the sea, all the rainwater on the platform is recovered into open tanks through floor drains, and then transported back to land in a closed manner for centralized treatment on land.
in the guangli river forest wetland park in dongying city, the oil pumps, oil storage tanks, photovoltaic panels and other facilities in the liuhu oil production management area of the xianhe oilfield of shengli oilfield have become a unique landscape in the eyes of tourists.
liuhu oil production management area manages 261 oil and water wells, with an annual crude oil and gas production of 264,700 tons. the noise from the oil pumps here is only 30 decibels when in operation, which is quieter than the sound of cicadas in the park. photovoltaic panels are installed in the idle areas of the well site. when the weather is good, the photovoltaic panels can generate enough electricity to meet the power needs of the oil pumps, and can also transmit the surplus electricity to the national power grid. the annual emission reduction is equivalent to planting 800 trees.
injecting "new" power into "old" oil fields
if conditions are available, we must move forward. if conditions are not available, we must create them and move forward. in the 60-year history of struggle, the oil workers of shengli oilfield have "moved from entrepreneurship to innovation", adhering to the shengli values of the new era of "patriotism, entrepreneurship, innovation, and openness".
in 2011, zhang zilin graduated from xi'an shiyou university with a degree in petroleum engineering and joined the fracturing institute of shengli oilfield petroleum engineering technology research institute. in august 2013, zhang zilin received the design task of the shengli oilfield salt 227 "well factory". this was the first time that shengli oilfield tried to construct a "well factory" with a new four-in-one design concept, which was a huge challenge for him.
"i stayed on the well for 34 days without going home and completed 89 sections of horizontal well fracturing, which was a record in sinopec at the time." this experience became an important milestone in zhang zilin's growth.
after 10 years of hard work, zhang zilin and his colleagues have mastered the combined fracture network fracturing technology, witnessed the tortuous development of shengli shale oil exploration and discovery and the breakthrough of the mine, and achieved their own growth and progress.
the shengli petroleum engineering company's fine tradition story museum showcases the spirit of hard work, struggle and dedication of the shengli petroleum engineering company's iron army and their glorious journey of doing business and serving the country through industry.
in the 70180sl drilling team, the words "victory yellow river iron army" are printed on the safety helmets. this title is the result of generations of victory drilling people insisting on the requirement of "building a steel drilling team", always practicing the original mission of "i contribute oil to the motherland", and showing the victory iron army's spirit of not fearing difficulties and being proactive.
in the 70180sl drilling team, looking up at the towering drilling platform, one can always feel its warmth and strength. the shadows of the workers on the platform are also stretched longer and longer by the sun, but their red work clothes soaked with sweat are becoming brighter and brighter.
