The Drilling of Deep Fractured Reservoir is Successful

On March 17, the general evaluation result of Hebei Science and Technology Progress Award in 2021 was announced, and the “key drilling technology and industrial application of deep fractured oil and gas reservoir” declared by Jidong Oilfield drilling and production institute won the third prize.

The achievement of “key drilling technology and industrial application of deep fractured oil and gas reservoir” is mainly aimed at the problems of easy reservoir damage, low rock breaking efficiency of bit and poor borehole quality in the early drilling process of deep fractured oil and gas reservoir in Jidong Oilfield, deepen the theoretical research on the damage mechanism of tight oil and gas reservoir and the influencing factors of rock breaking efficiency of bit, and guide the research and development of leakage prevention and plugging technology of deep fractured oil and gas reservoir Reservoir protection drilling fluid and high-efficiency rock breaking and speed-up supporting tools form a set of key drilling technologies suitable for deep fractured oil and gas reservoirs. After being popularized and applied in the test of deep fractured oil and gas reservoir in Jidong Oilfield, this research achievement has achieved remarkable results in improving reservoir protection effect, drilling speed and borehole quality.

While solving many technical bottlenecks in the drilling of deep fractured oil and gas reservoirs, this research achievement has driven the coordinated progress of domestic technologies such as leakage prevention and plugging, reservoir protection and drilling speed increase of deep fractured oil and gas reservoirs, improved the core competitiveness of drilling technology, solved the key technical problems restricting the drilling of deep fractured oil and gas reservoirs, and played a reference and demonstration role for the exploration and development of similar oil and gas reservoirs at home and abroad.
