Drilling rate rise 19.7%, life expectancy increased by 3.88 times, saving about 1.05 million drilling costs.

July 29, reporters from the Zhongyuan Oil Field postdoctoral research station was informed that the world’s first bionic own intellectual property rights only oil drill 103 wells in yuanba rock Xujiahe successfully tested.

Statistics show that only Φ241.3 mm impregnated diamond bit average ROP 0.77 m / hour, footage 16.1 m, and with the wells, compared with the formation adjacent rock bit, drilling rate rise 19.7%, life expectancy increased by 3.88 times. Only this one bit at a well used, can save drilling costs for the oil field is about 1.05 million.

From the perspective of Bionic Engineering, developed a new type of impregnated diamond bit – Bionic oil drills, hard and strong oil and gas wells Drilling abrasive to provide an effective rock breaking new technology.

To speed up the oil and gas exploration and development in Northeast of the process, solve Xujiahe slow formation of the drilling rate and bit life is short of technical problems, by the end of 2006, Dr. Zhongyuan Oilfield Tech Postdoctoral research project began, trying to find animals from natural soil solution.

After the study found that dung beetle with non-smooth surface morphology, with drag reduction, wear and desorption functions; Citellus mouse claw toe, and wear with high ground-breaking features. Soil animal skin and claw toes in the wear or molt could continue to grow after the self-regeneration function gave him great inspiration.

He bionic non-smooth theory and self-regeneration concept applied to the rock drill, after the northeastern region of the Xujiahe lithology-depth research, targeted for development of bionic bits. After studying more than two years of hard work, Dr. Gao Ke and the research team was led in June 2009 succeeded in developing a Φ241.3 mm bionic oil drill.

“Developed the first bionic bit only on the good results obtained, which led to me and my team added a great deal of confidence and courage. I believe in the near future, we developed the bionic oil drill bits will definitely solve the Quanguo even hard and abrasive world strong challenge to contribute to the drilling. “Dr. Gao Ke told reporters.

“Bionic bit is good, fast drilling speed, long life, we are willing to use. Proposed to optimize the structure to improve the bit to our team to test well.” Bearing drill 103 wells in Zhongyuan oil field yuanba Southwestern Drilling Company 90102 drilling crew Platform Manager Wei Shijun said with satisfaction. Before 90 102 drilling team tries to use the strata lot is only well-known manufacturers of impregnated diamond bits and PDC bits, its penetration rate and bit life are not as good as bit, they did not bionic bit hopeful. However, in the face of the facts, they changed their views, and the improved bionic bit full of hope.

Currently, Dr. Gao Ke led the research team, also invited the experts, are tense, meticulous, comprehensive diagnosis of the drill bit, analysis, in order to develop a more reasonable, better performance of the bionic oil drill bits for oil field development speed contribute to the block .
