发表了过去三年里在Alaska和California水力压裂泵注施工的 4 5口井所测量的井底压力数据的分析结果。其中 30口井资料来源于安装在油管上或者偏心工作筒内的存储式压力计 ,其它 15口井在环形空间反映出压力上升 ,压裂液体系是延迟硼酸盐瓜胶或线性HEC凝胶。把测量数据与Keck等人的关系式进行对比 ,结果表明在数值和关系趋势上二者存在较大的系统误差 ,并且证明了这些误差净压力分析和成功进行脱砂压裂改造的影响。另外 ,在压裂增产期间 ,对井底压力的精确预测也是必要的
Published the results of the analysis of the bottom hole pressure data measured at 45 wells in the Alaska and California hydraulic fracturing pumps in the past three years. Thirty of the wells were sourced from a storage pressure gauge mounted on a tubing or an eccentric mandrel and the other 15 wells reflected a pressure increase in the annulus. The fracturing fluid system was delayed borate guar or linear HEC gel . Comparing the measured data with that of Keck et al., The results show that there is a large systematic error between the two in terms of the value and the trend of the relationship, and the net pressure analysis of these errors and the impact of successful sand fracturing are proved. In addition, during fracturing stimulation, accurate prediction of bottom hole pressure is also necessary
