文章以某油田的断块区为例,主要针对于复杂板块的油气田开发中后期所存在的问题进行了总结分析,然后提出了油井整体二次压裂技术、难动用储量研究、剩余油分布与评价技术、近解远调等主要做法。同时对这些方法的效果进行了分析研究,发现具有较好的经济效益以及开发效果,对此类油藏的开发有一定的指导作用。
Taking the fault block area of an oilfield as an example, this paper mainly analyzes the problems existing in the middle and later phases of oil and gas field development in complex plates. Then it puts forward the overall secondary fracturing technology of oil well, the study of refractory reserves, the remaining oil distribution and Evaluation techniques, near solutions and other major approaches. At the same time, the effects of these methods are analyzed and studied, and it is found that the method has good economic benefits and development effects, which can guide the development of such reservoirs.
