[Abstract]:The reservoir thickness of Putaohua reservoir in Mao-402-3 block of Aonan oilfield is poor, and the risk of overall development and implementation is great. In order to further understand the geological characteristics of Mao-402-3 block, using seismic data, combined with the new drilling data in the block, the geological characteristics of block structure and reservoir are re-recognized, and the contact relationship between fault and sand body is described. On this basis, the design of horizontal wells is optimized, and the optimal selection of reservoirs and optimal design of horizontal wells across faults are carried out to realize the rational production of the same reservoir on both sides of the fault, and to explore ways to improve the production degree of complex blocks of faults in peripheral oil fields. Ensure effective development of the block. This paper makes full use of drilling, seismic, logging and other data, taking synthetic seismic records as a bridge, carries out fine interpretation and mapping of the grape flower in the study area, and carries out seismic inversion and reservoir prediction studies, on the basis of which, The characteristics of stratigraphic interface, stratigraphic distribution, fracture cutting relationship and trap characteristics are systematically studied. According to the reservoir characteristics of the study area, the conventional attribute, the frequency division attribute, the dessert attribute and the inversion attribute slice are studied separately, and the inversion attribute is combined with the inversion attribute to carry on the multi-period comprehensive characterization. The comprehensive prediction of the favorable development area between layers has been completed. Based on the results of structural analysis, seismic attribute analysis and inversion prediction, the authors comprehensively analyze and identify the sand body development areas from the point of view of sedimentary environment, structural conditions and main controlling factors. On the basis of the known oil and gas conditions of adjacent wells, it is suggested that five favorable drilling wells should be drilled. On this basis, 3D geological modeling is carried out, and the optimization design of horizontal wells is studied by numerical simulation software, and the horizontal well pattern and horizontal section direction are selected. Horizontal section length, vertical distance from injection well to horizontal well and perforation position of horizontal well.
