In this paper, zhundong of Xinjiang Oilfield of Huoshaoshan Huonan,Huo 8 studies to a large number of Rock core, logging, logging and seismic data, based on the integrated use of sedimentology, sequence stratigraphy, evaluation of multi-well logging, seismic Stochastic simulation of three-dimensional modeling and other advanced combination of multi-disciplinary reservoir characterization technology, in-depth study of the structural characteristics of the reservoir, reservoir distribution and sedimentary characteristics, so as to enhance and improve the effects of oil field development.Oil-bearing formation of Huonan and Huo 8 area pieces in Huoshaoshan reservoir is to assume an entire two stage opposing gyration from bottom to top and the photogenic order change of flat surface is obvious. According to introductory evolution of deposition analyses, H5 , H4 on the lower part is the lacustrine facies, H3 , H2 , H1 on upper part is the delta. The entire one lake returns array deposition system from bottom to top. In order to keep crude oil continuing developing, it is necessary to ascertain reservoir geology structure, deposition appearance, the collection nature grit body up, the reservoir being not a homogeneity, stores collection space type and their connectedness up. It will help to build the reservoir geology model, to adjust the reservoir development scheme thereby, to reach the dependable crop, and finish the high yield purpose. For this purpose , originally, fire piece of 8 area level grounds spring forms H1 , H2 , H3 , H4 , H5 formation carrying out tier of meticulous small tier of partition contrasts , tearing structure characteristic up , reservoir deposition prepares tiny appearance of deposition, the oil reserve distribution characteristic each other, reservoir superficial characteristics. The reservoir is not a homogeneity and an overall evaluation in thesis pair of Huoshaoshan reservoir Huonan ans builds up the meticulous geology of reservoir 3-D model which is the oil reserve project and numerical value simulate the model studying surplus oil distributes the geology. The main results as followed: 1) Huoshaoshan oil-bearing formation is an entire one lake from bottom to top (from H5 to H1). H5 is partly deep lacustrine facies deposits which forms into the dolomite, sandstone, mudstone taking form despise each other tier of complicated reservoirs types; H4 belongs to shallow lacustrine facies deposition , tier of dolomites interactive taking form thickly stabilize the seat shape grit tier and thick deposits; H3 is delta outside leading edge, the degree developing dispatches the grit body which gives first place to the mudstone; H2, the H1 oil layer group belong to the delta inner leading edge, the undersea unsteady diffluence runway grit body developing and becomes the main reservoir.2) The difference of Huoshaoshan oil-bearing formation is the combination dividing for upper part contains oil gas combination (H1 , H2 , H3 oil layer group) and contains the lower part of an oil gas two packs (H4 , H5 oil layer group). South the two-dimensional area earthquake datas of Huoshaoshan and the well logging data make an explanation of the stratum contrast stretches cloth again and helps us to discover a fault newly 2 6. Tearing distribution has area contrary and wash away the slippery character and form the Huoshaoshan. The tearing tectonic framework of right-handed fire south arc transports structural form exhibition cloth has the certain effect. That fire is carried on the back in the south towards the high steep back structure developing to squeezing strain under the effect on contrary powerful fire east fracture zone in the area northern west askew.
