新型预测地层破裂压力模型及其应用

A New Model to Estimate Formation-Parting Pressure and Its Application

新的预测地层破裂压力模型与国内外现有的模型不同,它是采用静力学分析建立的;考虑了上覆岩层压力、地层孔隙压力、构造应力和岩石抗拉强度等因素对地层破裂压力的影响。但是,必须将动态弹性参数转换成静态弹性参数,才能用测井资料估算地层破裂压力。

Huang Hexong et al.A New Model to Estimate Formation-parting Pressure and Its Application.WLT, 1993;17(4):296～301 A new model for estimating formation-parting pressure,which differs from the existing ones at home and broard,has been set up on the basis of statics analysis.Taken into consideration is the effect of overlay pressure,formation pore pressure,structure stress and tensile strength on formation-parting pressure.But, dynamic elastic parameters must be transformed into static elastic parameters so as to estimate formation- parting pressure with logging data.
