摘要
王庄油田为储量近亿吨的具强水敏性的稠油油藏,由于缺少对强水敏机理的深入研究,加之受取心井资料限制,无法准确描述储层水敏纵、横变化规律,阻碍了该油田的开发。利用室内水敏流动试验、X-衍射、激光拉曼、含油薄片分析等技术,对储层主要特征及影响水敏的主要因素进行了研究,建立了一套适合强水敏油藏的水敏室内评价方法,并利用测井解释的方法开展了水敏纵、横变化规律研究。实践证明该方法能够有力的指导王庄油田强水敏油藏的开发。
Wangzhuang Oilfield is a heavy oil reservoir with strong water sensitivity and one hundred million tons reserves. It was difficult to describe the vertical and horizontal change of reservoir water sensitivity for the lack of thor-ough studies of strong water sensitivity mechanism and limitations of cored well data,so that it prevents this oil reservoir from developing.The main reservoir charac-ters and the influence factors of water sensitivity were studied using lab water sensitivity flow test,XRD,laser Laman,oiliness slicing analysis etc,and a set of meth-ods for lab water sensitivity evaluation was built suit-able for the oil reservoir of strong water sensitivity.The variation rule of water sensitivity in vertical and hori-zontal was investigated through log interpretation.Prac-tice proved that this method may guide development of oil reservoir with strong water sensitivity in Wang-zhuang Oilfield.
