油藏开发中应用原油气相色谱指纹技术的可行性研究

原油气相色谱指纹技术应用于油藏开发的基本原理是原油全烃气相色谱"指纹"的变化是原油非均质性的具体表现,目前主要用于油层连通性研究和油井的分层产能研究。实际应用效果证实了该技术方法与传统方法相比具有简便、实用和有效的优势,但仍存在一些应用可行性问题,需要加强油层非均质性问题研究和油层连通性研究及油田开发过程中流体非均质性变化特征研究。

Feasibility Study on Application of Gas Chromatographic Fingerprint Technique in Reservoir Development

The basic principle of using gas chromatographic fingerprint technique in reservoir development was that the changes of full hydrocarbon gas chromatographic "fingerprint" were concrete representations of heterogeneity of oil,it was mainly used for studying the reservoir communication and stratified productivity of wells.Application result shows that compared with traditional method,the technique is more simple,practical and effective.There still exist some problems,these should be solved by further studying the heterogeneity,reservoir communication and the characteristics of heterogeneous changes of fluids in oilfield development.
