2014年5月9日,中国石油川庆钻探工程公司钻采工艺技术研究院(以下简称钻采院)新研发的一批页岩气油基钻井液产品,运抵威远H3-1页岩气井,等待接受现场检验。这种产品在页岩气钻井过程中可起到保护储层、保持井壁稳定,以及解决水平井钻井防卡等井下复杂问题的作用。若产品现场试验成功,将有望降低页岩气开发的综合成本,提高页岩气井的开发效益。面对四川长宁—威远地区31个平台、134口页岩气水平井的战略部署,自主研发适合非常规油气勘探开发的优质钻井液迫在
On May 9, 2014, a batch of new shale gas oil-based drilling fluid products newly developed by the Drilling Technology Research Institute of China Petroleum Chuanqing Drilling Engineering Corporation (hereinafter referred to as Drilling & Production Technology Institute) arrived in Weiyuan H3-1 Shale Gas wells, waiting to accept on-site inspection. This kind of product can play a role in reservoir protection, stability of the wellbore wall, and in solving downhole complicated problems such as anti-well drilling in horizontal wells during shale gas drilling. If the field test is successful, it is expected to reduce the overall cost of shale gas development and improve the development benefit of shale gas wells. Faced with the strategic deployment of 31 platforms and 134 shale gas horizontal wells in Changning-Weiyuan area, Sichuan, self-developed high-quality drilling fluids suitable for unconventional oil and gas exploration and development were forced to
