THE RESEARCH ON MAIN CURVATURE METHOD APPLICATION IN CARBONATE GAS RESERVOIR''''S STRUCTURAL FRACTURE PREDICTION
主曲率法在碳酸盐岩气藏储层构造裂缝预测中的应用研究

In this paper, the authors discuss the theory and precondition when main curvature method is used for carbonate gas reservoir's structural fracture distributing prediction; educe the main curvature value calculating formula based on differential geometry; propose a method to calculate the critical main curvature value and establish a calculating model for main curvature method. With the Jialingjiang group Reservoir as a case, we predict Jia~3_2 and Jia~3_4 two zones' fracture distributing using this method. The results are concided with the field's geologic situation and producing facts, which shows the method's feasibility and rationality.
