Study Of Reservoir Description For High Density Well Pattern In West Of Central Saertu

As the development of oil-field,the west of central area in Saertu oil field entering highly water-cut stage?It is particularly important to research the remaining oil distribution regularities.In order to ensure production supply,measures for tapping potentials of the remaining oil must be determined.There are many key factors which affect the block's oil-gas accumulation,oil-water distribution,deliverability and reserves,such as wide area,well spacing of compact and high density,various types of sand body,rapidly changed reservoir development and so on.For these reasons,by using the method of mono-sandbody identification and classify,typical sand-body microfacies analysis and separate mode of deposition,to research.Then the block have be formed,which is profitable to establish dense well pattern's geological database.Therefore,detailed comparison is very basic and important work to the west of central area.Theory of fluvial deposit and high-resolution sequence stratigraphy was used in this research.Furthermore proposed a fluvial facies comparative method,which “surfaces association under the standard layer control based on Enclosed skeleton section area,the guidance is depositional model-contemporaneous fault model,priority approaching and partition closure step by step,genesis moving boundary in the end.” According to previous research results and the reveal of Planar sedimentary microfacies of dense well spacing area's 150 depositional time units,Pu,Sa,Gao reservoir of the west of central area are the northern provenance.By using geological model and numerical simulation of reservoir,the paper… In this paper,mainly through the establishment of and adopt reservoir numerical simulation method,the block's development indexes is forecasted and the distribution rule of remaining oil are analyzed,finally confirmed tap the latent power object are main reservoir layer S2 and P?.After predict the reservoir development indices of the west of central area of Saertu oil field and contrast four kinds of development plan,finally the development of the reservoir optimization scheme is presented,which reservoir with the method of polymer flooding will reach high recovery degree.
