摘要:为了揭示中国南方3 套海相页岩的勘探潜力差异,利用黔南、渝东南和湘中地区典型钻井的岩心
实验分析、钻井、压裂测试等资料,从先期建造和后期改造等方面对成藏条件进行对比。结果表明:①五
峰组—龙马溪组为台内坳陷深水陆棚相硅质页岩型,生烃潜力大和储层物性好,含气量和地层压力均
较高,为最有利勘探开发层系;优质页岩厚度、保存条件和可压性均是选区评价的重点。②九门冲组为
被动大陆边缘深水陆棚相粉砂质-硅质页岩互层型,生烃潜力大,但热成熟度高,物性较差,保存条件复
杂,埋深大,为重要接替层系;热演化程度、构造稳定性和埋深均是选区评价的重点。③大隆组为裂陷
盆地深水台凹泥岩-灰质泥岩互层型,生烃潜力大、物性好,但夹层多,黏土含量高,顶底板封盖性差,含
气量较低,为潜在有利层系;有利相带、页岩连续厚度和可压性均是选区评价的重点。④川中、川南、川
东南地区的五峰组—龙马溪组,川中、黔南、宜昌地区的九门冲组,湘中涟源地区的大隆组均是页岩气
勘探开发有利区。

Abstract :In order to reveal the exploration potential differences of three sets of regional marine shale in southern
China ,the accumulation conditions were compared from the aspects of early transformation and post-reformation
by using the data of core experiment analysis ,drilling ,fracturing test of typical wells in southern Guizhou ,
southeastern Chongqing and central Hunan area. The results show that :(1)Wufeng-Longmaxi Formation is sili-
ceous shale in deep continent
