On June 12, drilling, kei igawa in drilling company 50506 team's 201 employees are well drilling operations-the H3 easier. This well is domestic first bite to field for the purpose of bamboo temple of shale gas horizontal well, on 29 May, this well realize smoothly finish in the open, average penetration rate and drilling machine on speed as high as 6.49 m/hours and 1967 meters per unit.

Wei 201-well is the first national H3 shale gas plexus type the first level JingZu a well. In east sichuan drilling company team 50506 employees to strengthen the application of new technology and summarized, improve the drilling speed. In the jialing river mouth, brussel formation serious leakages such difficulties as well, points for drilling parameters optimization, comprehensive drilling measures, formulate through the use of high quality and the collapse of a drilling fluid, the implementation of the mud blocks strong drilling technique, security drill to completion, down into the deep well casing cementing success. Wei 201-well drilling safety to the H3 finish well depth for the first time, realize the mud blocks drilling technology and strong in the upper strata JingZu cluster the inclined playing fast technology, and use only 4.5 hours to complete cementing operation, success explore shale gas leakage under horizontal Wells of the safety of the complex spray fast drilling technology, for the next shale gas horizontal well drilling accumulated experience .
