| 中文摘要:苏77区块处于生态环境脆弱的半沙漠半草原地区，采用丛式井开发方式，不仅可以加快产能建设，而且可以降低钻井成本，保护环境，便于气田维护管理。针对苏77区块钻井存在的技术难点，根据地层自然增降斜及方位漂移规律，从平台部署、井身轨迹剖面、钻具组合、PDC钻头选型及钻井液体系及性能维护等方面进行优化，形成了一套适应苏77区块的丛式井优快钻井配套技术，有效地提高了机械钻速，缩短了钻井周期及平台建井周期，加快了产能建设。其中，苏77-6-5井完钻井深3167 m，钻井周期仅为9.98天，创造了整个苏里格气田定向井最短钻井周期记录。 |

| Abstract:Su 77 block is located in a fragile ecological environment of half desert and half grassland, cluster wells can accelerate productivity construction, lower the drilling cost, protect environment and is convenient for gas field maintenance management. According to the drilling difficulties in Su 77 block and based on the formation natural deflecting law and azimuth drift pattern, optimization was made on platform deployment, well profile, bottom hole assembly, PDC bit selection, drilling fluid system and its performance maintenance, a set of matching technologies was formed for optimized and fast drilling with cluster wells suitable to Su 77 block, the penetration rate was effectively improved, drilling period and well construction cycle in platform were shortened and productivity construction was accelerated.
