摘要： 根据克拉玛依小拐油田的压裂退液资料, 总结了该油田的退液特征, 绘制出Cl- —QP 曲线, 根据Cl- —QP 曲线来预测油水层;提出了压裂液退液参数, 利用这些参数可判断地层的供液能力、渗透率、压裂所造裂缝的导流能力、压裂后地层受污染的情况, 并可对压裂效果作出定性评价, 分析判断中低产井低产的原因, 为制定下一步生产措施提供依据。

Abstract: Based on fracturing fluid withdrawal data in Xiaoguai oilfield, i ts characteristics were summerized, and Cl- —Qp curve prepared for predicting oil/water layer.Furthermore, the parameters of fracturing fluid withdrawal were presented to identify formation deliverability, permeability, fracture conductivity and post-fracturing formation damage and to quali titively evaluate fracturing effect and determine the reason of low production of oil well.All these offer basis for drawing up next development project.
