一种基于多相介质理论的油气检测方法研究

目前采用的油气检测方法和技术严格意义上讲都是基于单相介质理论的,而含油气储层是多相介质的,因此,造成了油气检测结果存在多解性和不确定性。本文以BIOT理论和实验室数据为依据,研究出一种快捷的油气检测方法。该方法已在中国塔里木、柴达木、准噶尔等盆地的10多个区块中得到应用,其检测油气的符合率高于现有的其它烃类检测技术。该方法在勘探阶段的油气检测方面和开发阶段油气藏动态监控方面具有广泛的应用前景。

A New Method for Hydrocarbon Detection Based on Multi-phase Theory

The hydrocarbon detection techniques used currently are generally based on the theory of single-phase medium, but hydrocarbon reservoir mostly is multi-phase medium, therefore, multi- solutions and uncertainties are existed in the result of hydrocarbon detection. This paper presents a fast way to detect hydrocarbon in accordance with BOIT theory and laboratory data. The technique called DHAF technique has been applied to several survey area and obtained good result where the coincidence rate for hydrocarbon detection is higher than other similar techniques. The method shows a good prospect of the application in hydrocarbon detecting at exploration stage and in reservoir monitoring at production stage.
