152区块是吉林油田英台采油厂英东高台子的主力区块,开采目的层为青山口组的高台子油层。该区块2002年4月份开发,9月份部署第二套井网,10月份产量最高达到864吨,之后进入快速递减阶段,自然递减4.33%,综合递减1.32%。为实现难采储量的有效动用,充分发挥储层改造的作用,提高现有压裂技术的水平,2010年上半年通过精心选井选层搞好措施挖掘剩余油潜力,实现了减缓两个递减的目标,在剩余油富集区域,对油层进行压裂改造,取得了良好的效果,为这部分难采储量的动用提供了技术基础。
Block 152 is the main block of Yingdong Gaotai, an oil production plant at Yingtai, Jilin Province. The target zone is the Gaotaizi oil layer of the Qingshankou Formation. The block was developed in April 2002 and the second well pattern was deployed in September. The production reached a maximum of 864 tons in October and then entered a rapid decline phase, decreasing by 4.33% in natural terms and decreasing by 1.32% in total. In order to realize the effective utilization of hard-to-find reserves, give full play to the role of reservoir reconstruction and raise the level of existing fracturing technologies, the remaining oil potential should be tapped through well-selected well-layer selection in the first half of 2010 to achieve a reduction of two decrements The goal of fracturing the oil layer in the remaining oil-rich area has achieved good results and provided a technical basis for the utilization of this part of the hard-to-find reserves.
