Abstract

Abstract

It is of importance to research characteristics and its nature of gas migration and accumulation within abnormal high pressure. Overpressures are observed in Xujiahe Formation, western Sichuan basin, in which a complete assemble of source, reservoir and caprock in interbedded pattern includes. Distribution of overpressure is plotted in vertical and in plane based on a number of data of measured pressure in sandstone reservoir. The evolution history of abnormal pressure is restored mainly by means of the numerical model on abnormal pressure, which are restrained by present measured pressures and ancient pressures calculated from compaction and fluid inclusion in sandstones. Vertical pattern of formation pressure includes a type of" two segments"in southern part and a type of" three segments" in northern part, and amplitude of overpressure in the latter is higher than in the former. The zone of strong overpressure is located in the Zitong sag.Overpressure increase in Xujiahe Fm from Early Jurassic to Paleocene is due to depositional factor, and comes from the effects of tectonic movement since Neocene. Three kinds of models of gas accumulation typically are put forward taking account of distribution and evolution of fluid pressure as well as other major elements of accumulation.
- abnormal high pressure,
- historical evolution,
- natural gas,
- migration,
- accumulation model
