深层低渗透油藏由于埋藏深、物性差,随着地层能量的亏空开发效果进一步变差,依靠自然能量开采,采出程度较低。马厂油田马26断块属于深层低渗透油藏,本文针对该块开展了深层低渗油藏合理井距论证及井网配置与优化的研究,从井网密度、注采启动压力等方面研究最后选取合理井距;在此研究的基础上,从不同油藏类型、沉积相带和裂缝展布方向等进行井网的合理配置与优化,取得了较好的开发效果。 Due to the deep burial and poor physical properties, deep low permeability reservoirs have a worse development effect due to the deficit of stratigraphic energy and rely on natural energy exploitation to a lesser extent. The fault block Ma 26 in Machang Oilfield belongs to the deep reservoir with low permeability. In this paper, the reasonable well spacing of deep low permeability reservoirs and well pattern allocation and optimization are studied in this paper. From the aspects of well density, injection and injection start pressure Finally, reasonable well spacing is selected. On the basis of this study, rational allocation and optimization of well patterns are obtained from different types of reservoirs, sedimentary facies belts and fracture distribution directions, and good development results have been achieved.
