冀东油田分层注水工艺技术

TECHNOLOGY OF SEPARATE ZONE WATERFLOODING IN JIDONG OILFIELD

冀东油田注水井井段长 ,油层埋藏深 ,层间矛盾突出。开发中后期的当务之急是解决层间矛盾。介绍在“九五”期间通过对分注井坐封测试不打捞技术、大压差长效分注管柱、套变井分注等问题的研究和攻关形成的适合冀东油田的分层注水工艺。介绍冀东油田几种分注管柱、配套工具以及“九五”

With longer well bore and deeper buried production formation in Jidong Oilfield, the key problem in the later development is interlayer conflict and how to solve it. The technologies of separate layer water injection (SLWI), which using among the Ninth-Five-Plan period, are mainly introduced such as non-fishing technology as setting and testing, separate layer water injection in casing deformation, atc. Several pipe strings of SLWI and their matching tools are also recommend.
