Fine Reservoir Description Of Region Mutou Oil 101 Well

With 30 years of development, Mutou oil 101 well has entered three high extraction stage, the local complex fault, oil and more are of non-serious injection of the contradictions in the development process have become increasingly prominent, serious constraints block benign Kaifa , mainly through the research, and further reveal the timber 101 remaining oil distribution Well, clearly the potential direction and fully tap the potential reservoir, to improve the effect of block development, make new wood oil production plant on a long-term stable production..This area of 101 wells for the work area, use of modern fine reservoir description technology theory and method, high-resolution sequence stratigraphy principles, according to the "standard level control phasor control cycle based on such methods when the comparison" to other stratigraphic correlation time, establish a fine reservoir stratigraphic framework, the original 12 small layer of sand was divided into 16 single in the base level cycle framework, the establishment of the reservoir heterogeneity and the correlation between base-level cycles ; in previous studies based on the theory of modern deposition by core observation, Background and deposition of sediment carried out of reservoir sedimentary facies, that the area is primarily fluvial sedimentary facies mainly underwater distributary channel, abandoned channel, crevasse channel and crevasse splay, natural levees, was identified deposition unit single sand facies distribution rules. Use of cores, flakes, particle size, properties and other conventional methods to evaluate the reservoir analysis. Interpretation of logging carried out twice. Analysis of 101 wells to develop the areas of wood characteristics, application deposits, logging and seismic inversion attributes the establishment of a small layer of deterministic model The establishment of a prototype model of the reservoir, the preferred method of stochastic reservoir modeling stochastic simulation, a reservoir model and carry out reservoir simulation. The remaining oil distribution on the well conducted study, tapping the potential Fangan proposed measures, to improve the well area 101, the development of wood Xiao Guo, two slow decline Ming Xian, formation Yali steady recovery, water cut rising rates are Youxiaokongzhi, to achieve savings Cai Ping Heng, to the "control of water stable oil" purposes.This paper studies that detailed reservoir description has entered the high water cut remaining oil in old oil fields and an important means to enhance oil recovery, as detailed reservoir characterization with the stages corresponding to different stages of the research aims, tasks and major The study is different from the corresponding information on the extent and accuracy have also different, it is necessary for the specific conditions of study, select the appropriate methods, techniques and software.
