3D TRAP EVALUATION METHOD OF SEARCHING FOR OIL-GAS RESERVOIR

摘要

The present invention provides a method of searching for oil-gas reservoirbased onTRAP-3D software, including: establishing a three-dimensional lithology andfault datacube of an exploration working area according to three-dimensional seismicdata andlogging data; dividing the three-dimensional lithology and fault data cubeinto severaldepth slices of the same depth, and performing an individual sand body unitdivision foreach depth slice; sequentially inputting the depth slices of the three-dimensionallithology and fault data cube into the TRAP-3D software for oil-gas reservoirevaluation.The present invention imporves the accuracy of three-dimensional trapevaluation, isconducive to precise searching of the oil-gas reservoir, can plot a Sweet-Spotdiagram ona plane, and get exhibits oil-gas trap amounts of different depths in alongitudinaldirection, and can obtain a total trap amount of the oil gas reservoir in theexplorationworking area.
