摘要
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. A drilled depth of 3 167 m for Su 77-6-5 well, drilling period was only 9.98 days,which is the shortest directional well drilling record in whole Sulige gas field.
