千米桥碳酸盐岩古潜山裂缝预测

Fracture Prediction of Carbonate Buried-hill in Qianmiqiao Area

岩石裂缝的形成取决于地应力超过岩石抗压、抗张或抗剪强度的大小,同时也与一定的构造样式相关。据此可以通过岩石应变量和岩层面的的曲率大小对岩石的裂缝进行定量预测。采用构造正演与反演相结合的工作流程,应用Midland Valley公司的3Dmove软件对千米桥潜山的碳酸盐岩储层的裂缝进行了预测。经勘探成果证实,预测效果良好,并对下步勘探提供了重要的依据。

Fracture is formed when the intensity of ground stress exceeds the compression strength, extension streng and shearing strength of the rock. On the other hand, the fracture is associated with the structure styles. Based on tl above, we can predict quantitatively the fracture distribution by the strain magnitude and the curvature of the formatio Adopting the program of combined structure forward and inversion and used the software of Midland Valley Corporati the fracture prediction has been made for carbonate buried hill in Qianmiqiao Area. Exploration results show the foreca is effective and this can provide an important base for the next exploration.
