The Effect of Plane Heterogeneity on the Reinjection Flow of Geothermal Reservoir:A Case Study of the Guantao Formation in Baoding City
摘要
Abstract
In the process of geothermal reinjection,some geothermal fields are facing shutdown due to the reinjection water flow being much smaller than the designed.This work took a block of Guantao Formation geothermal reservoir in Baoding City as the research area in order to solve the problem of lower water injection during the reinjection process.Numerical simulation software was used to couple the thermal field with fluid dynamic field,and numerical simulation calculations were carried out for four different non-homogeneous strata to establish the evaluation method of maximum reinjection flow rate.The results show that the maximum reinjection water flow decreases with the intensification of planar heterogeneity,and the reinjection effect decreases as low as 35%of that in homogenous strata.The planar heterogeneity in the area between reinjection and production wells can affect reinjection effectiveness by 20%to 65%.This method can reasonably adjust the planar heterogeneity and reinjection flow rate,and effectively ensure the reinjection performance,which can be extended to other reservoirs with similar geological conditions.关键词
