| 摘 要： | 火山岩、风化壳白云岩等缝洞储层基质孔隙度计算是测井评价亟需解决的难题之一.本文首先将全直径流纹岩声波实验公式(2005年,李宁)与国内外常用的基质孔隙度计算公式进行了细致的对比;进而就该公式在中基性火山岩、风化壳白云岩等缝洞储层中的适用性进行了深入讨论,并以岩心分析资料为基础,详细给出了该公式与其它公式在计算上述储层基质孔隙度时的误筹分布.误差统计结果表明该公式具有更高的精度.通过中国东部和西部三家油田70口井的实际应用验证,在孔隙度从1.5%到15%范围内,该公式不仅适用于酸性火山岩储层,而且适用于中基性火山岩、风化壳白云岩等缝洞储层基质孔隙度的评价.同时,该公式能够最大限度地减小扩径、岩石蚀变等复杂地质条件对计算结果的影响,实用性更强.

| Abstract: | Matrix porosity calculations of fractured and vuggy reservoirs,such as volcanics and weathered dolomite,are one of the problems urgently needed to solve in well-log evaluation.In this paper,we first compare the an empirical formula for porosity calculation from full diameter rhyolite core experiments with the matrix porosity formulas commonly used.We discuss the applicability of the empirical formula in fractured and vuggy reservoirs,such as intermediate-basic volcanics and weathered dolomite.Based on core ... |
