Abstract

Abstract: Based on the mechanism of gas reservoirs formed by natural fluid fracture and on the rock mechanism,this paper,closely combining fundamental characteristics of gas reservoirs in yangxin series in south aichuan.discusses the mechanism of abnormally high pressure formation and convertion,and sets up a physico一mathematical model of quantitative prediction of the pressure. Teati fled by oil field pressure data,the absolute error of predicted pressures is generally less than 2. OMpa,the fractional error leas than 5.000.

Key words: Abnormally high pressure, Formationl, Prediction, Yangxin series, south sichuan
