淮南煤田太原组煤系非常规油气勘探开发技术

在对淮南煤田太原组前期油气勘查工作调研的基础上，结合重大实物发现（油气显示层位和现场含气量测试），提出了针对山西组下伏地层的井下钻孔布设方案及其井身结构设计，并综合掌握实物发现地矿井地质构造资料，进一步提出了针对淮南煤田阜凤逆冲推覆构造带下盘系统（原地系统）太原组含煤岩系油气资源调查的地面探井布设方案及其井身结构设计。在此基础上，提出以"井下钻孔+地面探井"相结合的淮南煤田太原组非常规油气勘探开发技术。 

The exploration and development of unconventional oil and gas in the Taiyuan Formation from Huainan coalfield

Based on the early oil/gas exploration work on Taiyuan Formation, Huainan coalfield, in conjunction with some significant physical discoveries(layers with oil/gas showing and site gas-content testing), we proposed the layout scheme of underground drilling and its well profile design in Shanxi Formation underlying strata. Additionally, the layout scheme of the ground test well and its well profile design aims to the oil/gas survey in Taiyuan Formation coal-bearing rock series located in the bottom wall system(in-situ system) subjected to Fufeng thrust and napped tectonic belt of Huainan coalfield. On the basis of that, it was first offered that the "underground borehole + ground test well" combined technology can be used to explore the unconventional oil/gas resources in Taiyuan Formation, Huainan coalfield.
