摘　　要：文章以某地区具有代表性的M2井组共8口单井,M3井组共6口单井为研究对象,探讨其在开发过程中形成的废水分类管理方法和钻井废水回用处理技术。通过划分污染区域、划分废物池功能、配套搭建废水池雨棚等井场清污分流措施,以及现场废水综合回用等废水分类管理措施。试验研究不同阶段产生的钻井废水配制钻井液胶液、配制压裂液的可行性技术,表明不同阶段产生的钻井废水均可用于配制钻井液胶液。通过采取各种措施,废水产生量可减少67%以上。This paper focuses on the typical shale gas well M2 and M3in Sichuan and Chongqing areas and discusses the classification management method of drilling wastewater and reusing treatment technologies.The wastewater was reduced through the effective management such as diverting wastewater from clean water and synthesized recycling.Meanwhile,the feasible technologies on reusing technologies of drilling wastewater for drilling fluid and fracturing fluid also studied.The drilling wastewater produced at different stages can be used to make drilling glue.With all kinds of measurements,the volume of wastewater has reduced 67%.It hoped to provide a reference for domestic shale gas drilling development.
