低渗油藏主要存在储层物性差,渗透率低,微裂缝发育,导致单井自然产能低。伴随着经济社会的不断发展,能源已经成为了各国和各级政府极其关注的对象。在我国,除了石油进口,国内石油的开采量也不断加大。低渗油田存在着开采难度大、生产周期短的问题,因此,延长低渗油藏井生产周期对油田增产有重要作用。本文将通过对低渗透储层特征、开发现状等问题进行探索,通过分析低渗油藏的低产机理,针对不同的油藏区块,不同的开发阶段,制定了相应的油田开发技术对策;同时根据油田开发实际,不断完善相应的提高低产井产量配套技术,使油井产量得以持续提高。
Low permeability reservoirs are mainly characterized by poor reservoir properties, low permeability and micro-cracks, resulting in low natural productivity of single wells. With the continuous development of economy and society, energy has become the object of great concern to governments at all levels and all levels. In our country, in addition to oil imports, the amount of domestic oil exploration has also been constantly increasing. The low permeability oil field has the problems of difficult exploitation and short production cycle. Therefore, prolonging the productive period of low permeability reservoirs plays an important role in oilfield production increase. This paper will explore the characteristics of low permeability reservoirs and the status quo of development. By analyzing the mechanism of low yield in low permeability reservoirs, corresponding oilfield development technology countermeasures are formulated for different reservoir blocks and different development stages. At the same time, According to the actual development of the oil field, we will continue to improve the corresponding technologies for improving the yield of low-yield wells so that the production of oil wells will continue to increase.
