摘要

基于涪陵、威远、长宁、泸州、渝东南等地区海相页岩气勘探开发实践,结合实验测试分析,总结中国南方海相页岩气差异富集的6个特征：①有机质丰度越高、演化程度越适宜,吸附气量和总含气量越高;②干酪根热解和液态烃裂解联合供气是海相页岩气的主要来源;③富有机质页岩比表面积和孔体积随演化程度增加表现出先增加后减小的特征,当有机碳含量为2.23%~3.33%时,储集层以油润湿为主,最有利于页岩气富集;④顶、底板厚度越大,页岩气含量越高,末次构造抬升时间越长、抬升幅度越大,页岩气散失量越大;⑤地层埋深与倾角对不同构造部位的控气耦合作用不同,存在两种页岩气差异富集演化模式;⑥生-储-保有效综合匹配决定了成藏品质,有效生气量和时段、适度孔隙演化、良好保存条件在时空的良好匹配是页岩气富集的一种重要配伍。图14表1参37

Abstract

Based on the exploration and development practice of marine shale gas in Fuling, Weiyuan, Changning, Luzhou and Southeast Chongqing in southern China, combined with experimental tests and analysis, six factors controlling differential enrichment of marine shale gas are summarized as follows: (1) The more appropriate thermal evolution and the higher the abundance of organic matter, the higher the adsorption and total gas content of shale will be. (2) Kerogen pyrolysis and liquid hydrocarbon cracking provide the majority of marine shale gas. (3) The specific surface area and pore volume of organic matter rich shale increased first and then decreased with the increase of thermal evolution degree of organic shale. At Ro between 2.23% and 3.33%, the shale reservoirs are mainly oil-wet, which is conducive to the enrichment of shale gas. (4) The thicker the roof and floor, the higher the shale gas content. The longer the last tectonic uplift time and the greater the uplift amplitude, the greater the loss of shale gas will be. (5) The buried depth and dip angle of the stratum have different controlling and coupling effects on shale gas in different tectonic positions, resulting in two differential enrichment models of shale gas. (6) The effective and comprehensive matching of source, reservoir and preservation conditions determines the quality of shale gas accumulation. Good match of effective gas generating amount and time, moderate pore evolution and good preservation conditions in space and time is essential for the enrichment of shale gas.

Key words： southern China; shale gas; differential enrichment; main controlling factors; factors matching; accumulation effect
