一、概述世界石油的储量和产量,有一半以上来自复杂岩性地层。用常规的砂泥岩测井系列和解释技术,对复杂岩性储层进行评价的作法在实际中碰到了困难。鉴于上述状况,美国德来赛——阿特拉斯测井公司于1985年4月,研制成 PROFRAC 测井分析专用软件,以解决复杂岩性地层储集层的评价问题。PROFRAC 软件,用 FORTRAN 语言书写,在 PE-8/16机上和 PE-3230机上,在 CLS(计算机测井系统)下运行;该软件通过人—机对话方式,最多可输入18件曲线、67个参数;进行泥质含量、孔隙度、含水饱和度、地层各种组分的计算;通过对处理井段地层放射性特性和电性特性的分析对比,结
First, an overview of the world’s oil reserves and production, more than half come from complex lithology. Using conventional sand-mud logging series and interpretation techniques, the evaluation of complex lithologic reservoirs has encountered difficulties in practice. In view of the above situation, the United States Dresdner - Atlas logging company in April 1985, developed into PROFRAC logging analysis software to solve complex lithology stratigraphy reservoir evaluation. PROFRAC software, written in FORTRAN language, runs on a PE-8/16 machine and a PE-3230 machine under a CLS (Computer Logging System); the software can enter a maximum of 18 curves and 67 Parameters; the shale content, porosity, water saturation, formation of various components of the calculation; through the processing well strata radioactive and electrical properties of the analysis and comparison, the knot
