摘要
以三塘湖油田牛东区块压裂井的施工资料为基础,采用降阻比法,分别对无机硼(GRJ)交联液(羟丙基无机硼压裂液)施工过程中前置液、携砂液阶段沿程摩阻计算方法分析对比,结合牛东区块现场实际施工资料,对管柱摩阻计算公式进行修正改进,提高了压裂施工摩阻计算公式的准确性,对今后该区块压裂施工管柱摩阻分析与计算具有普遍指导性。
Based on operation data of fracturing wells in block Niudong in Santanghu oilfield, the friction calculation method of pad fluid and carrying fluid during the operation of GRJ crosslinked fluid are analyzed and compared respectively by using the method of antifriction ratio. Calculation formula of string friction is improved by combining field operation data of block Niudong, which increased the accuracy of string friction calculation formula, and provided a guideline for the string friction analysis and calculation of the block.
