截至2017年5月6日,长宁—威远国家级页岩气示范区累计产气量已突破40×10~8m~3。自2014年规模建产以来,该示范区已累计投产平台28个、水平井136口,目前日产气750×104 m~3。中国石油西南油气田公司(以下简称西南油气田)2006年率先在国内开展页岩气地质评价,2009年率先开展先导试验,2012年启动长宁—威远国家级示范区建设,2014年实施规模建产,2016年启动深化评价与规模上产,创造了国内页岩气勘探开发多项第一,在长宁—
As of May 6, 2017, the accumulated gas production in Changning-Weiyuan national shale gas demonstration area has exceeded 40 × 10 ~ 8m ~ 3. Since the construction of large-scale production in 2014, the demonstration zone has put 28 production platforms into operation and 136 horizontal wells, with a daily production of 750 × 104 m ~ 3. PetroChina Southwest Oil and Gas Field Company (hereinafter referred to as the Southwest Oil and Gas Field) took the lead in carrying out shale gas geological evaluation in China in 2006, took the lead in carrying out pilot test in 2009, started construction of Changning-Weiyuan National Demonstration Area in 2012, In 2016, we started to deepen the evaluation and scale production, creating a number of first domestic shale gas exploration and development in Changning -
