Method and apparatus for predicting while drilling using seismic and drilling in target stratum

An apparatus for predicting while drilling using seismic and drilling data in a target stratum, comprising:

• a first obtainment module configured to obtain two-dimensional drilling data and two-dimensional logging data, and generate depth-domain geological stratification data based on the two-dimensional drilling data and the two-dimensional logging data;
• a matching module configured to match the depth-domain geological stratification data with time-domain horizon data to construct a time-depth pairs dictionary;
• a second obtainment module configured to obtain three-dimensional seismic data, and extract Gradient Structure Tensor (GST) characteristic attribute data, amplitude energy attribute data and attenuation attribute data from the three-dimensional seismic data;
• an construction module configured to determine a first contribution degree corresponding to the GST characteristic attribute data, a second contribution degree corresponding to the amplitude energy attribute data and a third contribution degree corresponding to the attenuation attribute data, and construct initial seismic drilling data characterized by a multivariate and multi-type composite attribute;
• a third obtainment module configured to obtain real-time two-dimensional data while drilling, and map the two-dimensional data while drilling into three-dimensional seismic data while drilling based on the time-depth pairs dictionary;
• an update module configured to update the first contribution degree, the second contribution degree and the third contribution degree based on the three-dimensional seismic data while drilling;
• and
• a generation module configured to obtain seismic and drilling prediction data of the target stratum represented by the multivariate and multi-type composite attribute based on an updated first contribution degree, an updated second contribution degree and an updated third contribution degree.
