| 摘 要： | 根据地震力学理论，建立了地震记录和测井数据之间的非线性映射关系，并据此构建了测井曲线。利用所构建的测井曲线，采用井壁稳定预测模型预测维护井壁稳定的安全钻井液密度窗口。采用该方法预测了却勒1井维持井壁稳定的安全钻井液密度，预测结果与实际钻井液密度非常吻合，表明该方法具有较强的工程适用性。

| Abstract: | According to seismic wave dynamic mechanics, the reasonable nonlinear mapping relationship between seismic record and logging data has been established. The model of logging data was constructed by seismic record . The acoustic wave velocity and density of the formation to be drilled was acquired by the model, then the elastic property and strength could also be estimated. Based on the wellbore stability theory, the safe mud weight range prediction model for borehole stability is established and successfully verified in Quele 1 Well. |
