workers' daily-china workers' network reporter wang dongmei
on august 27, china national offshore oil corporation announced that the "xuan ji" system produced by my country's first intelligent production line for rotary steerable drilling and logging while drilling has achieved a new milestone of 40,000 meters of cumulative footage and 10,000 hours of total downhole time in iraq's missan oilfield, marking a new breakthrough in the high-end manufacturing capability and large-scale operation capability of "xuan ji", which is of great significance to the comprehensive creation of an independent, controllable, safe, reliable and competitive modern high-end oil and gas equipment manufacturing industry chain and to ensure national energy security.
the "xuanji" system is a rotary steerable drilling and logging-while-drilling technology independently developed by cnooc. it is a revolutionary and subversive technological breakthrough in my country's oil drilling and logging fields, and is known as the "crown jewel" of oil drilling technology. it can accurately control the drill bit to drill into the oil reservoir in the rock formation several thousand meters underground, greatly improving the efficiency of oil and gas resource exploration and development.
the "xuanji" system used in iraq's missan oilfield is the first batch of products produced by cnooc's "xuanji" intelligent production line. through the process upgrade of the intelligent production line, the "xuanji" system has achieved a significant improvement in anti-abrasiveness, deflection stability and downhole parameter monitoring capabilities. in the past two years, it has completed the operation of 48 wells with high quality and a 100% operation success rate, becoming the first overseas large-scale application unit to complete "40,000 meters of footage and 10,000 hours of operation".
the intelligent production line of the "xuan ji" system has laid a solid foundation for building the high-quality, large-scale, high-efficiency and low-cost delivery capabilities of "xuan ji", provided strong support for promoting the global large-scale application of "xuan ji", and is a vivid manifestation of accelerating the cultivation of "new quality productivity".
