扶余油田中区非城区泉头组四段微构造精细研究

Study on Microstructure in Member 4 of Quantou Formation,Non-town Block of Fuyu Oil Field's Middle Block

油田勘探开发初期,构造隆起的高部位一般是油气藏开发重点。随着勘探开发的深入,特别是到了油田注水开发的中、后期,油田挖潜调整的重点转至寻找剩余油。剩余油分布的主控因素包括油层微型构造、沉积相类型、储层非均质性、前期开发方案与开发工艺等。研究表明注水驱替构造高部位的正微构造区是潜在的剩余油富集区。运用小波反演精细解释扶余油层顶面的微断层,并对13个时间单元微构造测井资料进行了精细研究。利用井震结合的方法分析了微构造对剩余油的控制作用,提出油田开发精心研究重点。

In the early phase of oil field exploration and development,high uplift is generally focus on.With further development,especially to the middle and late of water flooding,finding the remaining oil is the most important.Controlling factors of the remaining oil are micro-structure,sedimentary facies,reservoir heterogeneity,pre-development project and reservoir engineering.The results show that the structural high part of the microstructure area is a potential residual oil zone in water-drive reservoir.The faults in Fuyu petroleum reservoir＇s top layer is reviewed and studied the 13 members＇ micro-structure in detail with logging and seismic datas.On this basis,the microstructure effect is analysed on the control of remaining oil and divided the micro-structure area of the potential remaining oil,promoted the important works in oil development.
