摘要
与普通油藏相比,厚油层油藏受沉积韵律、层间干扰的影响较为严重。在进入高含水期后,由于油藏厚度大,层内水淹差异大,剩余油的分布错综复杂。开展厚油层油藏高含水期水驱效果开发评价对于后期实施提高厚油层油藏水驱采收率技术具有重要的指导意义。本文以M油藏为例,利用油藏工程方法并结合行业开发评价标准对其开发效果进行了分类评价,分析了该厚油层油藏提高开发效果存在的主要矛盾及需要改善的问题,为下一步改善水驱开发效果指明了方向。
Compared with the common reservoirs, the thick reservoir is effected by sedimentary rhythm and the inter zone interference seriously. In the high water cut stage, the distribution of the remaining oil is complex as the reservoirs are thick and the differences of the flooding in the layers are big. It is important to evaluate the effect of waterflood of thick reservoir in high water cut stage to improve the thick reservoir waterflood oil recovery technology in the later stage. Taking the M reservior as an example, their development effect are evaluated in the classification by using reservoir engineering methods and combined with the development evaluation criteria in industry. The main problems in improving development effect are analyzed and the direction of the work in the future is pointed out.
