地化录井技术在东濮凹陷油气开发中的应用

东濮凹陷的许多开发区块目前都已进入高含水开发期,分析剩余油的分布情况和油层的水淹程度是现阶段该区块油层评价的关键所在。该文从油藏地球化学的角度,系统地介绍了地化录井技术评价开发井油气层的理论依据与主要评价参数的获取方法。通过大量的试验和现场应用,分析总结了东濮凹陷主要开发井油气层的地化录井显示特征;研究了综合运用地化分析技术和热蒸发烃色谱分析技术,随钻评价开发井储集层性质与原油性质和油层开发动态的方法。应用实例证明综合应用地化录井技术评价开发井油气层的效果是比较明显的。

The application of geochemical logging technology in oil and gas development in Dongpu Sag.

At present many development blocks in Dongpu Sag are in the period of high bearing water, and analyzing remaining oil distributing state and the watered-out degree of oil zones are the key work for the area oil zone evaluation. As for the oil reservoir geochemical, the paper systematically introduced the theory basis of evaluating oil zones for development wells by using geochemical logging technology and the methods by obtaining the major evaluating parameters. By large amount of testing and well site application, the author analyzed the main chemical logging showing properties in oil and gas zones of the development wells in Dongpu Sag, studied comprehensively using geochemical logging technology and thermal evaporation hydrocarbon chromatographic analysis technology and the methods of evaluating reservoir properties while drilling and oil zone developing trends. The examples showed the better result could be get by comprehensively using geochemical logging technology to evaluate oil and gas zones of development wells.
