提出了川东石炭系储集体系统中地层压力弹性能量场的概念模式，并用地层压力弹性能量场势描述了该区中等隆起幅度构造，地层构造复合圈闭气藏和各主要高陡背斜带上地层压力弹性能量场势的剖面特征。进而定量地评价出川东石炭系气藏的保存条件与地表侵蚀作用的密切相关，而与构造断层无关。据剖面形态将该区地层压力弹性能量场势分为钟罩型，丘状平稳型和偏漏斗型三种，它们分别代表着各自气藏弹性能量的保存和散失的程度。

ELASTICITY ENERGY FIELD POTENTIAL RESEARCHES ON RESERVOIR BODY FORMATION PRESSURE OF CARBONIFEROUS IN EAST SICHUAN

??The conceptual model of the elasticity energy field potential of the formation pressure of Carboniferous reservoir body in East Sichuan is proposed out.The central uplift structure,combination trap gas reservoir of formation stracture and sectional characteristics in the main high and deep anticlinal belt of the area are described by elasticity energy field potential of formation pressure.It is quantitatively evaluated that the preservation conditions of Carboniferous gas reservoirs in East Sichuan are closely relative to surface erosion action but irrelative to the structural faults.According to the sectional patterns,the elasticity energy field potentials of the formation pressure in the area are divided into three types with bell shape,stable hillock shape and funnel shape.They respectively indicate the Preservation and loss degrees of elasticity energy in each gas reservoir.
