华池油田华152区长3油藏属典型的特低渗油藏,1996年正式投入开发,在开发过程中油井堵塞频繁严重影响了开发效果,加剧了油藏的递减。本文通过对长3油藏的地质特征的认识、堵塞机理的研究,确定了适应性解堵技术并在现场应用中取得了较好的经济效益,同时为同类油藏的开发提供了借鉴资料。
The reservoir of reservoir No. 3 in Huachi Oilfield Hua-152 is a typical ultra-low permeability reservoir, which was officially put into operation in 1996. During the development process, the blockage of the well often severely affected the development effect and aggravated the decline of the reservoir. Based on the understanding of the geological characteristics of Chang 3 reservoir and the study on the mechanism of blockage, this paper determined adaptive plugging technology and achieved good economic benefits in field application, and provided reference for the development of similar reservoirs.
