To address the problem that the description of geological structure features in the North North Block test area of Lama Dian oil field is not accurate and comprehensive. GPTMap reservoir automatic mapping software was used to map the reservoir structural features, sedimentation features, well location map, compartment development status and oil formation connectivity status and control degree based on well logging data into a cloud map. The results show that gptmap reservoir mapping software has the characteristics of comprehensive function coverage, high work efficiency and rich image color, solves the problem of graphic reuse, and realizes the two-dimensional and three-dimensional reproduction of reservoir geological data;The structure of the test area is relatively gentle, gradually steepening from west to East, and the dip angle of the stratum is between 5º~,6°, plunging northward at 3°~4°;The target oil layer belongs to river delta sedimentation, which is mainly a low bend distributary channel sedimentary model in flood distributary plain environment. It has the characteristics of more intervals, larger thickness and complex sedimentary model;After subdividing the sedimentary units, the interlayer between the sedimentary units is mainly class I mudstone interlayer, and the penetration rate is between 36.7% ~ 89.0%; The overall sand body is mainly connected between channel sand body and channel sand body; The plane heterogeneity of the reservoir is strong, and the permeability difference between wells is large. The detailed description of the geological conditions of the test area provides a geological basis for the formulation of subsequent development plans.
