On August 1, 2017, drilling from Lu 202 well to 6 095 m completed drilling, setting the bottom temperature of shale gas in Sichuan-Chongqing region as high as 145 ℃. The oil-based drilling fluid independently developed in China was well immersed for 3 534.96 h, etc. Two new records have pushed shale gas exploration in China to a new depth. Well Lu222 is located in Jinjiatan Formation, Jinjiatan Village, Jiang’an County, Yibin City. It is one of the evaluation wells of PetroChina Southwest Oil and Gas Field Company and the first horizontal well in the new block of “Lunsitou” Drilling on the 24th. The well is designed to be 6 080 m in depth and 1 500 m in horizontal section. It is drilled by 70549 drilling crew of China Chuanqing Drilling Engineering Company Ltd.,
