针对哈南地区夫特构造砾岩储层低孔、低渗及非均质特征,研究了灰色系统精细评价砾岩油藏的分析准则和处理方法,利用测井、钻井取心、试油及有关地质资料,匹配、拟合和提取参数,以统计分析特征及其准确率、分辨率研究砾岩储层岩性、物性与含油气情况,生成和建立了该区夫特构造砾岩储层精细评价的参数、指标和解释系统。通过该区夫特构造20 多口井砾岩储层的精细评价解释和自动分析处理,取得了明显的实用效果。

In connecting with low-pore , low-permeability and heterogeneity of Hananfute structure conglomerate reservoir , this paper studies the analytical criterion and processing ways to evaluate conglomerate reservoir by gray system ,match ,fit and extract parameters through well-logging ,by coring-drilling , oil test and relevant geologic data , then statistical analysis proper value ,accuracy and resolution ,study lithology physical properties and hydrocarbon-bearing situation of conglomerate reservoir ,generate and build parameters ,index and interpretation system of Hananfute structure conglomerate reservoir. Obviously practical results have been got through fine evaluation and interpretation and automatic analysis processing of more than 20 wells’ conglomerate reservoirs in Hananfute structure. The methods , mainly processing of software and examples of actual application have been shown in this paper .
