Detailed Reservoir Description For Miao Nan Block

The MiaoNan block consists of Miao130, Miao134, Nen1 and Miao22 block, At the same time, including Mu210 ~ Miao132 well area of southeast of Miao130 block.Each block by block technique, data and other restrictions,Has not carried out systematic reserv eoir description.As an important potential XinMu oil, Sand body changes fast in this are a, the distribution of oil and water complex,On the regional potential condition is alway s lack of in~depth understanding of.In view of the above problems,The comprehensiv e utilization of the static and dynamic aspects of the data, through theinterdisciplinary r esearch method, based on the seismic interpretation and reservoir prediction,reservoir fine description, analysis of the structure and the characteristics of fault block.The Nen 1 and Mu 210 to Miao132 block by the sparse pulse,geostatisticsinversion technology to reserv oir inversion, the establishment of the block sequence stratigraphy. Study of sedimentary microfacies types, sedimentary facies and sand body distribution. Analysis of the reservoi r plane, layer and interlayer reservoir heterogeneity. For each layer and the single well co ntrol reserves are given by volumetric method, set up the blockfine 3D geological mode l, analysis of each block of injection production relationship and control degree of water flooding, summarizes the causes and types of remaining oil block.Analysis well network adaptability of the Nen1 block,considering from the oil source,sediment,reservoir, tra p, and the results of oil, it is considered that the tectonic slope zone and the high porosi ty and high permeability zone is the favorable conditions of forming reservoirs, preferabl y 3favorable, 4 assessment wells.
