摘要
对于海上水平井开发油田,剩余油的研究应建立在明确主控因素基础之上。采用数值模拟方法开展主控因素下的剩余油分布研究。研究表明,对于浅水三角洲沉积类型油田,剩余油主要由储层韵律、沉积微相、夹层发育状况、开发方式共同控制。总结了各主控因素剩余油富集位置及合理的开发方式。其中,层内夹层及多期河道叠置控制下的剩余油占比最重,是未来调整和挖潜的主要对象。
For the development of offshore horizontal wells, the study of remaining oil should be based on clear main control factors. Research on residual oil distribution under main control factors by numerical simulation method,the research showed that for the oilfields which developed by horizontal wells predominantly, the main controlling factor of remaining oil should be clear as the basis of numerical simulation. in this paper, both the position and digging direction of the enrichment of remaining oil were summarized, it also gives the conclusion that physical conditions, sedimentary microfacies, interlayer, development method were the most important influence factors on remaining oil which characterize the oilfield. Among them, the remaining oil in the interlayer interlayer and multi - stage river channel superposition control is the heaviest, which is the main target for future adjustment and potential tapping.
