Preliminary Study on the Feasibility of Segmental Development of Thermal Reservoir in Jixian System Wumishan Formation

Abstract

In order to explore the occurrence of geothermal reservoirs in deep bedrock of the earth, and provide the basis for the exploration, development and utilization of geothermal resources, this paper makes full use of the existing exploration results and lots of first-hand data, based on the analysis of lithological characteristics of each member of Wumishan Formation, the test data and parameters of geothermal wells with the 3rd - 4th and the 1st - 2ad intake layers are analyzed and compared. The results show that the difference between the two intake layers is obvious, the parameters such as unit inflow and permeability coefficient of the former are larger than those of the latter; the water quality is also better than the latter. The "red strata" developed between the two intake layers can play a good role in water resistance, and can be used as the water barrier between the two, indicating that the Wumishan Formation can be developed by segmentation.
