摘要/Abstract

摘要： 以海上M油田N油藏为例,阐述了以沉积微相、储层非均质为剩余油分布规律的主控因素,分析了开发过程中的含油饱和度变化规律.重点研究了综合利用脉冲中子测井及产液剖面测井求取剩余油饱和度的方法,提出了开发阶段不同时期含油饱和度的计算方法.以沉积相为控制条件,以时间为轴,应用随机建模的方法,建立了不同开发阶段的含油饱和度四维模型.依据研究成果,提出对目标油田剩余油挖潜采取油井细分层系、卡层堵水、补孔等措施,取得了较好的经济效果.生产实践证明,在沉积相控条件下,整合静态及套管井测井资料建立剩余油饱和度分布四维模型的研究思路是可行的.

Abstract: The sedimentary facies and reservoir heterogeneity are the main control factors for the distribution of remaining oil.Taking N reservoir of M Oilfield as an example,the variation of oil saturation in the development of oilfield was analyzed.Two methods for calculating remaining oil saturation of oilfield including the pulse neutron lifetime log and the production profile log were investigated.The calculation method of oil saturation at different time in development stage was proposed.The sedimentary facies were taken as the control condition,and the random modeling method was used to establish four-dimensional model for studying the distribution of remaining oil in different development stage according to the chronological order.Some measurements such as subdivision of reservoir,killing formation and water block-off,re-perforation were applied in the objective oilfield.The better economic results were obtained.The production practice proved that it was available to develop four-dimensional model of remaining oil distribution under the control of reservoir sedimentary facies using the new method.

Key words: pulse neutron lifetime log, water cut, oil saturation, sedimentary facies, remaining oil distribution, four-dimension model, random modeling
