The present application belongs to the field of
artificial intelligence geoscience application and dense
reservoir evaluation technology, and particularly to a dense reservoir structure
porosity inversion method based on rock physical prior embedding. The method comprises the following steps: S1: obtaining conventional
logging data and calibration data; S2:
logging data preprocessing; S3: constructing rock physical prior features; S4: constructing a rock physical prior embedding input matrix; S5: constructing an integrated
coupling model; S6: extracting bidirectional sequence features in the well
depth direction; S7: performing
nonlinear inversion; S8: constructing a rock physical prior constraint
loss function; S9: performing joint
global optimization; and S10: outputting intelligent inversion results of structure
porosity. The continuous curves of free
porosity, micro-microporosity and clay porosity output by the present application can directly serve reservoir effectiveness evaluation, movable fluid identification, reserve calculation and development interval optimization, and provide reliable parameter support for oil and gas exploration and development.
