Development of technology basically achieved domestically

And conventional oil and gas and tight oil and gas horizontal well is different from horizontal shale gas well drilling and completion of the difficulty lies in how to achieve excellent fast segment shale Shale gas revolution drilling and completion, ensure wellbore quality, reduce drilling and completion costs. China shale gas drilling and completion technology research research started late, but rapid progress.
China's shale gas exploration and development of technology and equipment essential to achieve localization, horizontal well costs have been declining, continue to shorten the construction period. Through technology introduction, digestion and absorption and research, China has natural gas fracturing basically mastered the shale gas geophysical, drilling, completion, fracturing and test gas and other exploration and development of shale gas technology. 3500 m to the shallow drilling and staged fracturing Hirai skilled jobs, have staged fracturing of horizontal wells up to 22 segments, up to 2130 meters of capacity. Self-developed mobile rigs, 3000 fracturing trucks and other equipment, as well as shale gas, "dessert" forecasting software, to achieve better application results in the exploration development. Horizontal well drilling and completion period is reduced from 150 days to 70 days, the shortest 46 days, the level of single well costs fell from 100 million yuan to 50 million yuan to 7,000 yuan.
