摘要
With the increase of resource exploration rate in Jianghan Basin, the difficulty in exploring conventional sandstone reservoirs is continuously enlarged. In recent years, by strengthening basic research and changing exploration ideas, the exploration breakthrough of carbonate reservoir and the effective promotion of shale oil field have been achieved. According to the exploration practice, in combination with the analysis and experiment data of drilling, testing, logging and cores, comprehensive geological research and favorable area evaluation were carried out in the study area. The research reveals the spatial distribution characteristics of lithological and lithofacies, sedimentary patterns, reservoir space types, oil-gas enrichment conditions, as well as accumulation mode. Moreover, it has been clarified that granular carbonate and mixed granular rock have good oil storage capacity, which are new types of oil reservoir for conventional exploration and development, and also the actual field for increasing reservoir and production, with a total resource of 3.7×108t. The facies assemblage of shale mixed with micrite (dolomite) has good oil generation ability, mainly distributed in the second oil group of lower Member of Xingouzui Formation. It is expected to achieve a breakthrough in the exploration of new field of shale oil, and the resource amount is predicted to be 3.62×108t. © 2024 Science Press. All rights reserved.
