鄯善油田含水高采出程度低开发难度大,为了大幅度提高采收率需要从改善驱油机理的角度出发,寻求适宜于油藏高含水期的开发方式。该文针对改善驱替介质和改变开发方式论述了鄯善油田注空气、注烃气、表面活性剂、MD膜驱油、微生物、周期注水、改变液流方向等技术的适应性,对比了其提高采收率幅度,认为液流转向技术、注烃气、表面活性剂驱油更适宜于鄯善油田高含水期后续开发,潜力较大。
In Shanshan Oilfield, it is difficult to exploit high water-bearing high water content. In order to improve oil recovery greatly, it is necessary to find a suitable development method for high water cut period of oil reservoir from the perspective of improving oil displacement mechanism. In this paper, the adaptability of technologies such as air injection, hydrocarbon injection, surfactant, MD film flooding, microorganism, periodic water injection, and change of flow direction are discussed in terms of improving displacement media and changing development mode. Improve oil recovery rate, that the flow steering technology, hydrocarbon gas injection, surfactant oil displacement is more suitable for shanshan oilfield high water cut-off development, great potential.
