水力压裂设计与注入流体效率密切相关。通常 ,这个参数是从分析校正试验压降来获得的。一种新的确定闭合压力解释技术是基于对Nolte的F函数的新型使用。油田实例证实 ,不论是对传统的渗透率的估算还是闭合压力以及注入流体效率的确定 ,有效应用F函数提高了水力压裂设计水平。
Hydraulic fracturing design is closely related to the efficiency of injected fluids. Usually, this parameter is obtained by analyzing the calibration test pressure drop. A new technique to determine closure pressure is based on the new use of Nolte’s F-function. The field examples confirm that the effective application of the F-function improves the design level of hydraulic fracturing, whether it is the estimation of traditional permeability, the closure pressure and the efficiency of injection fluid.
