卫星油田水淹机理及解释技术研究
|
摘要
卫星油田经过长期的注水开发,有些区块已出现水淹现象,进入早期水淹阶段,油层水淹问题逐渐突显出来。油层水淹以后,必将导致储层物性参数、含水饱和度、地层水性质、润湿性、油水相对渗透率及压力系统的变化。这一系列的改变,直接影响流体性质识别、原油产量下降、采收率降低、原油产量下降,对开发射孔、提高开发效益、保证油田稳产造成重大影响,水淹层的解释工作就变得至关重要。
面对动态的水淹层解释,传统方法解释有点困难,因而必须加强基础理论和实验研究,提高对油层水淹机理及岩电关系变化规律的认识,进而针对性地选择测井系列和解释方法。本文首先从本油田储层地质特征出发,选定适合本油田地质特点的水淹层测井系列,既有利于当前测井解释、油藏评价工作需要,而又有利于今后水淹层评价要求,保证测井系列的一致性;然后初步建立起适应本油田特点的水淹层测井解释技术,直接应用于油藏早期或中期水淹层评价,有利于提高油田开发效益,缓解水淹带来的矛盾。
通过本课题研究,为外围油田及一些薄差储层水淹层解释工作提供一定的理论支持,对于提高油田的开发效益,进而实现油田的稳产是十分必要的。
After long term flood development ,Wei xing oil field has some blocks which emergence water flooding phenomen, entering early stage water flooding period. Oil layer water fiooding problem has been concened.After flooding, the reservoir will result in physical parameters, water saturation, formation water quality, wettability, relative permeability and water pressure system changes. This series of changes, directly affect the fluid nature of the identification, decline crude oil production,and reduce the recovery of crude oil production .The perforation of the development, development effectiveness and oilfield production have also been affected. The interpretation of flooded layer becomes essential.
It is difficult to interpret the dynamical fiooding layer with the traditional method.Therefore we must enhance basic theory and experimental study and advance knowledge of water flooding mechanism of oil field and rock-electrical relationship changing regular.According to them ,we choose the logging suite and interpretation method.The paper analyses the reservoir geologic characteristic first, and choose adequacy water flooding interpretation method.The method is suit for well log interpretation presently and the needs of reservoir evaluation,being also suit for the reservoir evaluation in thefurture,to insure the compatibility of loging suite.We establish the accommodate log interpretation technologe for the oil field gradually,which directly apply water flooding layer evaluation in the early and middle period.This can enhance development effect.
Through the subject study,we can afford some theory technologe of water flooding tterpretation for the outer field and some thin-bad reservoir.It is essential for enhancing development effect of oil field and to insure the stable yields of reservoir.
