| 摘 要： | 碳酸盐岩储层是低孔低渗储层,裂缝相对发育,只有裂缝走向与地应力方向平行、成锐角(小于45°)或呈钝角(大于135°)时,其裂缝才有可能成为有效缝。同时,从油气运移机理上讲,地应力又控制油气富集情况。本文主要从这两方面阐述地应力在千米桥潜山碳酸盐岩储层中的应用。

| Abstract: | Carbonate reservoir is the low-porosity and low-permeability reservoir,which fracture trend parallels crustal stress direction.Only when they form acute angle(less than less than 45°)or obtuse angle(greater Than 135°),the fractures may become effective.At the same time,crustal stress controls the enrichment condition of oil and gas from migration mechanism.This paper formulates the application of crustal stress in Qianshan carbonate reservoirs of Qianmiqiao area from two aspects. |
