摘要
随着油田开采程度的加深,层间矛盾愈显突出,尤其是见水层数的增加,直接导致了层数动用的降低,影响油田开发效果。细分开发层系是提高油田剖面动用程度、降低含水、改善开发效果、提高采收率的有效途径之一。本次以鄯善油田西Ⅰ顶部区作为细分开发层系研究对象,通过分析该区存在的主要问题,重点研究分小层的剩余油分布规律,编制了4个层次7个试验方案,经过数值模拟优化及经济评价,最终推荐方案4作为鄯善油田细分开发层系的试验方案。
With oil field production deepgoing interlayer contradictions are even more distinct, Especially water breakthrough layer increased directly cause the decrement of amount of producing layer and affect the effectiveness of oil field development. Subdivision of development layer series is one of effective ways to improve amount of producing layer, Decrease water content, Improve development result and enhance recovery. In this paper the top area of Xi l in Shanshah Oil Field is taken as study objective of subdivision layer series of development. By analyzing the existing problems in the area, We reaearch the remaining oil distribution in substratum and design 7 test projects for 4 layers. Though optimization of numerical simulation and economic evaluation the project 4 was recommended to be as test project for subdivision of layer series of development in Slum-shah Oil Field finally.
