常用的油气成藏时期大致可分为三类五种:一类是根据油气成藏要素分析法,包括圈闭形成期和烃源岩排烃期;第二类是利用储层成岩矿物分析法,包括自生伊利石K—Ar测年和储层流体包裹体均一温度测定;第三类是油气藏饱和压力分析法。单一方法有各自的基本原理和优点,同时又有很大的局限性,难以确保研究结果的准确性。本文通过冷湖五号构造油气成藏时期分析表明,将各种方法综合应用,并将研究结果纳入到油气成藏事件的过程中进行分析,去伪存真,能够获得较为可信的油气成藏时期。
Commonly used hydrocarbon accumulation period can be divided into three types of five: one is based on hydrocarbon accumulation factor analysis, including trap formation period and source rock expulsion period; the second is the use of reservoir diagenesis mineral analysis Including authigenic illite K-Ar dating and homogenization temperature of reservoir fluid inclusions. The third category is reservoir saturation pressure analysis. Single method has its own basic principles and advantages, but also has great limitations, it is difficult to ensure the accuracy of the findings. In this paper, the analysis of the accumulation period of hydrocarbon reservoirs in Lenghu-5 tectonic setting shows that the comprehensive application of various methods and the incorporation of the results into the process of hydrocarbon accumulation events can be used to analyze the results of the hydrocarbon accumulation events and to obtain more credible hydrocarbon accumulation periods.
