| 摘 要： | 应用有限单元法在求解几何形状复杂的问题斱面的优势,对人工压裂后产生的任意分布的支裂缝采用线单元进行描述,将油藏和裂缝看作一个渗流系统建立统一的有限元模型。本文以5点法井网为例,对边界封闭压裂井进行模拟。针对油井产能,模拟研究了支裂缝的数量、支裂缝长度以及裂缝的导流能力对其的影响规律。分析模拟结果得出:支裂缝数量的变化不能够较大的影响油井的产能;增加支裂缝长度不能够较大幅度的提高油井的产能;裂缝的导流能力的提高能够对油井的产能和见水时间起到较大幅度的影响。 |

| Abstract: | Basedonthe advantagesof the finite element method in computingcomplex geometric problems,thelinear elementwas usedtodescribe the branch fracturesafter artificial fracturing.Takingthereservoir and fracturesas one percolation system,uniform finite element modelwasestablished. In thispaper,takingfive-spot pattern asanexample, artificial fractured well with closed boundarywassimulated.Effects ofthe branch fracture number, the branch fracture length and the branch fracture flow conductivityonoil well productivityweresimulated and analyzed.The results indicatethat： change of the branch fracturenumber has littleeffectto oil well productivity;increasingthe branch fracturelength has little raisingscope to oil well productivity; increasingthebranch fractureflow conductivity has largeeffectto oil well productivity and water breakthrough time. |
