【摘要】：新民油田构造位于松辽盆地南部扶新隆起带向三肇坳陷倾没斜坡上,泉四段顶面构造为从南东向北西倾没的单斜构造。新民油田储层为泉头组泉四段以及泉三段的上部地层。主力油层是扶余和杨大城子油层。储层岩性主要为粉砂岩,胶结类型主要是孔隙式和接触式,胶结物主要为泥质。新民油田1990年投入开发,经历了投产上产阶段、基础井网注水开发阶段、加密调整稳产阶段、精细油藏研究挖潜阶段,油田进入中含水期,储层认识程度低,剩余油认识不清楚,导致产能效果逐年变差,低产井和高含水井在新井中比例较大。本文通过对新民油田储层的精细划分和对比,对构造特征和沉积特征进行了描述,开展了储层四性特征和非均质性特征研究,建立了沉积相和储层特征模型,对油藏进行了深入的研究。通过油藏研究成果预测出了能有效提高新井产能的井位,为低渗透油田在后续开发中提高产能建设效果提供依据。本文对低渗透油田如何通过优化产能井位提高产能建设效果,具有一定的借鉴价值和指导作用
[Abstract]:The structure of Xinmin Oilfield is located on the slope of the Fuxin uplift belt in the southern Songliao Basin, and the top structure of the Quan4 member is a monoclinal structure dipping from the south to the north. The reservoir of Xinmin Oilfield is the upper stratum of the fourth member of Quantou formation and the third member of Quan formation. The main reservoir is Fuyu and Yang Dachengzi reservoir. The reservoir lithology is mainly siltstone, the cementation type is mainly pore type and contact type, and the cement is mainly muddy. Xinmin Oilfield was put into development in 1990, which has gone through the stage of production and upproduction, the stage of basic well pattern water injection development, the stage of infilling and adjusting stable production, the stage of fine reservoir research and tapping potential, the stage of oil field entering middle water cut stage, and the low level of reservoir recognition. The understanding of the remaining oil is not clear and the productivity effect becomes worse year by year. The low production wells and the high water cut wells have a large proportion in the new wells. In this paper, through the fine division and correlation of the reservoir in Xinmin Oilfield, the structural and sedimentary characteristics are described, the four characteristics and heterogeneity of the reservoir are studied, and the sedimentary facies and reservoir characteristic model are established. The reservoir is studied deeply. Based on the reservoir research results, the well location which can effectively improve the productivity of new wells is predicted, which provides the basis for improving the productivity construction effect in the follow-up development of low permeability oil fields. This paper has certain reference value and guiding function for how to improve productivity construction effect by optimizing productivity well location in low permeability oil fields.
