本文主要研究内容
作者范佳鑫（2019）在《黑山梁油区长6油层采油井产量变化与注采井间连通性变化关系研究》一文中研究指出：黑山梁油区位于鄂尔多斯盆地陕北斜坡中部,其主力油层为三叠系延长组长6油层,在2010年实施注水开发,但是目前采油井产量变化不一,注水受效程度不均衡。开展在单井组内,采油井产量的变化与注采井间连通性变化的关系研究,对于下一步注水开发工作具有重要的意义,前人在此方面的研究较为薄弱。本文以单注采井组为研究单元,对采油井产量变化进行分析,通过对产量上升型、产量下降型采油井与注水井之间对应层位自然电位曲线、自然伽马曲线、声波时差曲线进行精细对比,总结产量上升型、产量下降型采油井与注水井测井曲线变化特征,从而指出采油井产量变化与注采井之间连通性的变化趋势,旨在为注水开发工作提供一种新的思路。通过本次研究,取得以下认识:1.根据采油井的产液量和产油量变化趋势,将研究区中部十个井组的42口采油井分为三类:产量上升型(19口),产量下降型(12口),产量不规律型(11口)。2.在28组产量上升型采油井与注水井中,两井测井曲线的变化特征为:由注水井向采油井方向,自然电位曲线负异常幅度变大的组合共23组,占比82%,自然伽马曲线数值变小的组合共17组,占比61%,声波时差曲线数值变大的组合共22组,占比79%,注采井间测井曲线的变化表明向采油井方向砂体渗透性逐渐变好,泥质含量降低,物性变好。3.在17组产量下降型采油井与注水井中,两井测井曲线的变化特征为:由注水井向采油井方向,自然电位曲线负异常幅度变小的组合共15组,占比88%,自然伽马曲线数值变大的组合共13组,占比76%,声波时差曲线数值变小的组合共15组,占比88%,注采井间测井曲线的变化表明向采油井方向砂体的渗透性变差,泥质含量增大,物性变差。4.通过对产量上升型采油井、产量下降型采油井与注水井间测井曲线变化分析,发现由注水井向上升型采油井方向,连通性由差变好;由注水井向产量下降型采油井方向,连通性由差变好,表明注采井间连通性的变化对产量具有一定的影响。5.根据不同类型采油井与注水井之间的连通关系变化,初步提出将某些产量下降型采油井转为注水井的措施,改变注采关系,在新的注采关系中,由注水井向采油井方向连通性由差变好,从而达到提高产量的目的。
