METHOD FOR LOOKING FOR OIL AND GAS RESERVOIR ON THE BASIS OF TRAP-3D SOFTWARE

摘要

A method for looking for an oil and gas reservoir on the basis of TRAP-3D software. The method comprises: establishing the three-dimensional lithological character and fault data cube of an exploration work area according to three-dimensional earthquake information and logging information (S101); dividing the three-dimensional lithological character and fault data cube into a plurality of depth slices with an equal depth, and performing separate sand body unit division on each depth slice (S102); and sequentially inputting the depth slices of the three-dimensional lithological character and fault data cube into the TRAP-3D software to perform the oil and gas reservoir evaluation (S103a, S103b). By means of the method, the accuracy of the three-dimensional trapping evaluation is improved, precise seeking of the oil and gas reservoir is facilitated, the dessert map on the plane can be drawn out, the oil and gas trapping amount of different depths in the longitudinal direction is displayed, and the total trapping amount of the oil and gas reservoir in the exploration work area can be obtained.
