摘　　要：川东地区海相地层沉积早（Ｚ—Ｔ２），断褶构造发生晚（Ｎ—Ｑ）。断褶构造发育程度低及隐伏构造内致密储层后生孔洞缝发育区控制气藏分布。梁平向斜内及两翼变陡部位发育众多的隐伏构造，向斜是气源区。根据地震资料解释出隐伏断层及构造，优选了３个构造，定出４口井位供钻探。The marine strain in the east6rn Sichuan Basin was deposited from Sinian to Middle Triassic, but the maturity of the faults and folds were formed from Neogene to Quaternary. The faults, folds,and the. secondary pores,holes and fractures have controlled the diStribution of gas pools. There are many blind structural traps inSide the Linngping syncline and in the steep areas of its two limbs. The syneline is the gas source area. The blind faults and traps have been recognized by seismic profiles. Three traps thought good for gas accumulation are preferred and four well locations have been suggested for drilling. It is probable to find gas pools in this area.
