摘要/Abstract

摘要： 原油密度是反映原油物理性质的主要参数,是录井精细评价储层“四性关系”的一项重要指标。二连盆地内凹陷受基底构造线、边界条件和受力不均一性等因素影响,油气藏的形成和油气分布差异性较大,不同地区、不同地层所产原油密度也有较大的差别,给录井综合评价储层含油性及预判储层产能增大了难度。为了解决这一难题,采用一种利用录井轻烃分析参数预测原油密度的计算方法,选取二连探区不同凹陷80余口井的轻烃录井参数,建立轻烃录井参数与储层原油密度之间的关系,通过优选相关系数,确定预测储层原油密度计算公式,解决判定储层油质问题,为定量判断原油性质提供了一种新的技术方法。

Abstract: Crude oil density is the main parameter reflecting the physical properties of crude oil and an important index for mud logging to finely evaluate reservoir’s "four-property relationships".The sags in Erlian Basin are affected by factors such as basement structural line, boundary conditions and stress heterogeneity. The formation of hydrocarbon reservoir and hydrocarbon occurrence differ greatly, and the density of crude oil produced by different regions and strata is also quite different, which makes it difficult to comprehensively evaluate the reservoir oil-bearing property and predict the reservoir production capacity. To solve this problem, this paper adopts a computing method of predicting crude oil density with mud logging light hydrocarbon analysis parameters. The light hydrocarbon logging parameters of more than 80 wells in different sags of Erlian area are selected to establish the relationship between light hydrocarbon logging parameters and reservoir crude oil density. By optimizing the correlation coefficient, the calculation formula of predicting reservoir crude oil density is determined, which solves the problem of deciding reservoir oil property, and provides a new technical method for quantitatively judging the properties of crude oil.
