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...

Description

technical field [0001] The invention relates to the technical field of geological exploration and development, and relates to a method for establishing a three-dimensional geological model of mud logging parameters. Background technique [0002] The existing 3D geological modeling generally adopts the combination of geological, logging, geophysical data and various interpretation results or conceptual models to generate a 3D quantitative stochastic model, including structural models, facies models and attribute models; the structural model is obtained through The well-connected strata are compared to form a synthetic seismic record, determine the time-depth relationship, establish an application layer velocity model based on the seismic synthesis record, and use the layer velocity model to perform time-depth conversion on the time-domain seismic body. Based on the seismic data in the depth domain, the faults and layers are traced, and the actual drilling breakpoints and laye...
