| 摘 要： | 新都气田蓬莱镇组气藏是由多套含气砂体组合而成的工业性气藏，河口坝为其最有利沉积微相，储层岩性以细粒岩屑砂岩、细粒岩屑石英砂岩为主，岩性较为致密，以中一低孔渗为主。含气地震响应模式为“低频、强振幅、低阻抗”；测井信息反映储层具有“二高三低”特征。

| Abstract: | The gas pools in the Upper Jurassic Penglaizhen Formation in the Xindu gas field, western Sichuan are believed to be the industrial gas pools consisting of a number of gas-bearing sandstone bodies. The favourable sedimentary microfacies is represented by channel mouth bar and submarine fan bar sandstones. The lithologies comprise fine-grained lithic sandstones and lithic quartz sandstones, which are relatively densed, with moderate to low porosity and permeability. The seismic response model for the gas-bearing sandstones displays the features of low frequency, high amplitude and low impedance, and the well-logs for the gas reservoirs exhibit the electrical properties of high AC, high resistance, low natural gamma-ray log, low neutron log and low density. |
