摘要
根据相似原理,采用电模拟装置,研究了水平井压裂过程中裂缝与井筒斜交的情况下,水平段井筒附近压力分布,油藏中的压力场形态,影响斜交裂缝产能的部分因素进行了探讨。并用本模型的实验结果与垂直裂缝情况下做了对比,评价参数对产能的影响。
Electrical analog experiments on the basis of the similitude principle is presented in this paper.By using the electrical model, the pressure distribution around wellbore,pressure contours,partial factors of affecting the productivity of inclination between fracture and wellborn in fractured horizontal wells are analyzed and investigated.The results of the experiments,compared with vertical fracture,effect of the parameter on the productivity is evaluated in the end.
