Reservoir Geological Modeling And Development Plan Analysis Of The Upper Es3 Low Permeability Reservoir In Lu44-Liu80 Block

The upper Es3 reservoir of Liuxi Lu44 Liu80 block, as the successor blocks for building productivity to the rolling development, has just a short production time so that we only have a vague understanding of its reservoir geological conditions. Before a full scope production, it is must to get an all round knowledge and understanding on the geological structure, layer distribution and nature of the reservoir to provide a reliable basis for the development of the exploration program and the corresponding adjustment.Regarding reservoir modeling, this thesis, on the basis of studying on the evolution of reservoir sedimentation and the sedimentary microfacies division of the sub layers, with the accordance of a single well log interpretation, to choosing the Phased Kriging modeling technology to establish the studying area reservoir parameter, and considering the oil water distribution, using Combined Phased Kriging technology to establish the studying area oil layer parameter.On the basis of reservoir modeling and through the study on spatial distribution of the reservoir and the heterogeneity assessment to the interlayer, the thesis does a comprehensive evaluation of the reservoir and a calculation of the original geological reserves in the study area. Through the statistics and analysis on the reservoir layers, thickness, horizontal distribution of the study area, it studies the division and arguments to the layers system in this area. The comprehensive analysis of the study area argues that the development should be divided into two sets, that is, upper sub layer and lower sub layer, with the bottom layer Es326 as the border line.Based on the layer division in the exploration, evaluated the natural energy, proofed the essentiality of artificial water injection and studied the injection production pattern. By means of the evaluation and study of development program parameter, advanced two layer systems and infill adjust, advanced the concrete technical measures for the recently exploitation adjust program.
