Domestic particle impact drilling technology field test for the first time
Daily news (reporter QuJian) of science and technology, according to China's oil its kei igawa drilling engineering company in southwest oil and gas field longgang - 022 H7 well recently, successful domestic particle impact drilling technology for the first time through the field test. Compared to the conventional drilling drilling in hard interlining, save a third time.
Preliminary test shows that using this technology, the conventional drilling rate of penetration 3-4 times; In deep well, ultra deep well and difficult to drill the formation, the technology is all the more its advantages.
China petroleum and aiming at the international forefront of technology, organization kei igawa drilling with China university of petroleum (Beijing) technology research and development and experiment was carried out. Beginning in 2010, after 3 years hard research, developed the particle drilling injection system and recovery system, the key equipment for particle injection tank pressure, circulation piping erosion wear, particle sedimentation return related indoor experiment, and the particle and the type testing in well control simulation inoue, verify the feasibility of the system.
To fully grasp the particle impact drilling key technologies, China's oil drilling kei igawa in longgang in early August 022 - H7 well in field test. At the scene under rigorous safety supervision, technical personnel fine installation and debugging of particle impact drilling using extended nozzle cone bit, from 022 - longgang H7 well, river horizon 2843.72 meters deep well drilling, with more than 1 hour well drilling to 2846.34 meters, a total of 8 tons injection particles, in the xujiahe river has realized rapid drilling in hard interlayer. A full set of equipment of the drilling system reliability and feasibility of drilling process have withstood the test.
