对杏十～杏十一区西、东部钻井降压恢复注水的认识

SOME KNOWLEDGE OF BLOWDOWN AND RECOVERING WATERFLOODING BYDRILLING WELLS IN THE WEST AND EAST OF XING SHUGANG 10 AND 11 AREAS

杏十～杏十一区西部和东部(以下简称西部、东部),因钻调整升降压进行恢复注水,由于做法不同见到的效果也不相同。这里的经验对今后钻调整井、加密井有一定的参考意义。

<ABSTRACT>: In the west and east of Xing 10 and 11 areas,recovering waterflooding is car-ried out by drilling some adjustment wells after blowdown. The result varies because of di|-fferent methods. Experiences obtained in practice have references for further drilling adjustment wells and infill wells.
