Multidisciplinary Fine Reservoir Description On Flooding System On Bei 3 Dong Area In Saertu Oil Field

Multidisciplinary study is a kind of composive reservior study. It is a kind of technology that with the application of geology, geophysical exploration, well logging and testing information, based on the thoeries of petrolium geology, tectonics and sedimentology, supported by reservior geology, sequence stratigraphy, seismic lithology, reservior geochemistry and related data bases, with the help of computers, operated by compound reserchers to reserch and discribe the reservior muti-dementionally.Refined reservior description means that after it is discovered, with multidisciplinay method, to recognize the geologic properties from different faces. At present, the oil field company arrange the geological task of reservior in developing and remainning oil prediction as the main content of reservior description. So refined reservior description is task and integrated multidisciplinary reserch is the way.In this article we aimed at the typical block of the east of B3D, to process refined water flooding reservior discription. Visual remaining oil distribution charts are built and danymic analysis is done combined with danymic and static materials. We reserch the original reservs of sedimentary unit and iner-part of it and the degree of producing. We also descibe the distribution of remaining oil after the injection-production adjustment. That may be reference for similar adjustment behind and meanwhile, that also become a pre-direction for the adjustment of other water flooding blocks in Sabei developing area.In the period of actrual work, during the process of building model, we acurately combine the fault points and fault surfaces. Ater arithmatic optimizing towards top suifaces, the token degree of the faults are detailed. We also optimize the arithmatic of the well point property dispertion and the arithmatic of between-well value inserion. According to the distribution properties of all the sedimentary units, to set the variation function, to optimize model and raise the precision of property model. In the process of numeric simulation, based on the actual condition, we optimize the raletive permeability curve, the permeability and saturation and so on. With the method of well group red supplement adjustment and well group presure maintaining, to proceed history matching and then finish the simulation for all the sedimentary units. With these methods, the simulation acuracy is raised.
