本论文针对文南油田高压低渗油藏开发中后期,面临层间矛盾突出,剩余油分布零散,认识挖潜难度大的局面,以沉积微相研究为基础,开展单砂体沉积微相和相控剩余油研究为基础的储层精细研究、相控剩余油分布研究和相控剩余油挖潜技术研究以及沉积微相约束下的井网布置研究,进一步探索高压低渗透油藏开发中后期提高采收率技术,并在研究成果的指导下,根据文南油田不同相控条件下的剩余油分布类型,开展了分类调整治理技术政策研究。
In this paper, aiming at the mid-late period of the development of high-pressure and low-permeability reservoirs in Wennan Oilfield, facing the contradiction between the layers and the remaining oil scattered, it is difficult to understand the potential of tapping potential. Based on the study of sedimentary microfacies, the sedimentary microfacies and facies Controlled reservoirs, controlled reservoirs, controlled reservoirs, studies on residual reservoirs, studies on residual oil distribution in phased-over, and studies on potential tapping of residual oil in phased-control and well pattern placement under the constraint of sedimentary microfacies, Yield technology, and under the guidance of the research results, according to the Wennan oilfield under different phase-controlled residual oil distribution type, carried out classification adjustment control technology policy research.
