摘要
采用降排量测试法对压裂过程中的流动阻力进行了计算。计算结果与试验结果共同表明 ,拖市油田近井地区裂缝宽度小 ,弯曲摩阻大 ,易造成砂堵。
Discharge reduction testing method is used to calculate flow resistance in fracturing process. Both calculation result and testing result show that in near-wellbore area the width of fracture is small, bending friction drag is big, by which sand plug would be easily caused in Tuoshi Oilfield. On the basis denoted above, a fundamental principle is proposed for low sand ratio design of fracturing operation in Tuoshi Oilfield.
