摘要: 本文基于自然流体压裂成藏机理和岩体力学,紧密结合川南阳新统气截基本特征,探讨异常高压形成和转化机理,进而建立定量预测气层异常高压物理一数学镬型.经矿场实际资并验证,气层压力预测值绝对误差一般小于2.0MPa,相对误差一般小于5.0%.

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
