摘要
针对大民屯凹陷古潜山油藏注水开发过程中遇到的水窜严重、水驱采收率低等问题,加强了古潜山内幕研究,在对储层特征及剩余油分布进一步认识的基础上,将常规水驱方法与渗析采油机理相结合,发展出多种井型组合注水、古潜山分层注水、异步注采等多元化注水技术,在扩大注水波及体积、提高储量动用程度方面有良好效果。该研究对同类型古潜山油藏的开发有一定借鉴意义。
The buried hill reservoir in Damintun depression has experienced problems of severe water channeling and low recovery rate during water flooding process.This paper studies the interior structure of the buried hill reservoir,including reservoir characteristics and residual oil distribution,combines conventional water flooding with imbibition oil recovery,and proposes multiple water injection technology including multi-well type combination water flooding,stratified water flooding,and asynchronous injection–production.The technology has achieved good results in expanding waterflood swept area and increasing the producing degree of reserves.This research has guiding significance to the development of similar buried hill reservoirs.
