Embodiment 1
[0050] Embodiment 1: as attached figure 1 As shown, the method for establishing a three-dimensional geological model of mud logging parameters includes the following steps:
[0051] Step 1: Obtain mud logging model parameters, including mud logging oil and gas index, mud logging dc index-rock hardness data and mud logging lithology data;
[0052] According to the discretization value of the existing mud logging fluorescence content data and the gas concentration ratio of the mud logging gas logging data, the mud logging oil and gas index is obtained;
[0053] Carry out regression analysis on the core hardness measurement value, the drilling dc index of rocks at different well depths and the acoustic time difference data, and calculate the mud logging dc index-rock hardness data;
[0054] Discretize the existing cuttings data at the mud logging site to obtain mud logging lithology data;
[0055] The second step: according to the mud logging oil-gas index, mud logging dc index...
