Abstract
It is prevalent and difficult to study oil-gas by inclusion in recent years. This paper presents time temperature index (TTI) method of judging hydrocarbon source condition by fluid inclusion in sedimentary rock. On the basis of fluid inclusion data of core in Ordos basin , TTI can be calculated out. We first calculate the capture temperatures and the capture pressure by the data of fluid inclusion microanalysis, then calculate the paleo-temperature gradient,the paleo-pressure gradient and the changable palaeo-temperature trajectory. Finally the time domain,the depth domain and the temperature domain of hydrocarbon-production can be worked out. We compare these calculated data with the data calculated in classic way , it shows that the inclusion TTI method is availabe and valid.
