| 摘 要： | 利用数值模拟方法，分别研究了裂缝方向对开发指标的敏感程度、裂缝长度与裂缝强度对开发指标的影响、裂缝方向与裂缝长度对开发指标的影响。结果表明．当裂缝强度较弱时．井距的选取可不考虑裂缝的影响；当裂缝强度较强时．对于注采井连线与裂缝线平行或相交角较小时，合理井距应是裂缝长度的2～2．5倍之间；对于注采井连线与裂缝线相交角较大时．井距的选取可不考虑裂缝的影响；合理的人工压裂造缝规模应控制在井距的一半以内。 |

| Abstract: | The effect of fracture direction on the sensitive level of development index, the effect of fracture length and its strength on the development index and effect of fracture direction and its length on the development index are studied respectively by using the method of numerical simulation. The results show that when the fracture strength is weak, the effect of fracture is not considered in selecting well spacing, when it is stronger, rational well spacing shall be between 2 times and 2. 5 times of the fracture length for the parallel of injector-producer line with fracture line or smaller crossover angle, for bigger crossover angle of injector-producer line with fracture line, the effect of fracture is not considered in well spacing selection. Rational fracturing scale of artificial fracturing shall be controlled within the half of well spacing . |
