摘　　要：为了充分认识并助力高效开发四川盆地南部高温深层页岩气,以钻井管理模式为研究对象,分析了该区块储层特征和钻井作业情况,创新性地提出了工程技术支撑管理模式,整合钻井定向、钻井液、提速优化、井控等专业类别,组建支撑团队,采用"团队技术支撑、参与甲方技术决策、辅助现场管理"三级工作模式,前线支撑组常驻甲方基地和现场,全面参与甲方技术攻关和组织管理,后方专家组通过气井工程信息化技术提供远程支持。研究结果表明:(1) 2020年至今应用该管理模式在A和B公司实施了120井次,A公司L203井区钻井周期由平均110 d降到100 d后又再缩短至了90 d,实现了两轮提速;(2) B公司平均钻井周期相比2019年缩短了23 d,区块钻井速度大幅度提高,钻井周期持续缩短。结论认为,该模式重新定义了甲乙双方合作模式,可根据甲方需求定制支撑范围,亦可在川内其他复杂区块推广,助力提速提效工程技术支撑管理工作。In order to sufficiently understand and support an efficient development of high-temperature deep shale gas,southern Sichuan Basin, both reservoir characteristics and drilling situation in this block were analyzed, and an engineering technological support management mode was innovatively put forward by taking the drilling management mode as an objective. A suite of support team was built by integrating directional-well drilling, drilling fluid, rate of penetration(ROP) increase and optimization, and well control comprehensively. And a kind of three-level working mode of "providing technological support, participating in Party A’s technological decision making, and assisting field management" was adopted. Specifically, one team of frontline support permanently should stay at Party A’s base to fully participate itself technological research and organizational management, and another team of rear expert should provide remote support through engineering information technology. Results show that this management mode has been applied 120 well times in Company A and B since 2020. The average drilling cycle in L203 well block of Company A is shortened from 110 d to 100 d and then to 90 d, and two-round ROP increase is completed. The average drilling cycle in Company B is 23 d shorter than that in 2019,the ROP is increased significantly whereas the drilling cycle is shortened continuously. In conclusion, this mode provides a new definition of cooperation between Party A and Party B, which customizes the support range according to Party A’s needs. It can be popularized to other complex blocks in Sichuan Basin to increase both ROP and efficiency.
