Research On Reservoir Characteristics Of Xi137Area In Xifeng Oilfield

The reservoir in the study area controlled by lithology belongs to low permeability reservoir,strong heterogeneity.The following problems need to be further studied:sedimentary facies do not carried out the system of the study, the distribution of favorable sedimentary facies do not determine; the study of the diagenesis and the petrologic characteristics is weak; the reservoir physical properties and pore structure of the resercoir do not be understanded in-depth; fracture distribution characteristics need further studyAiming at the problem of strong reservoir least permeability and low extent research in Xifeng oilfield, with comprehensive applications of geology, coring, well-logging and core analytical datum, the paper carries out research on rock type, sedimentary faces, reservoir characteristics, fracture characteristics and reservoir comprehensive evaluation under the instruction of sedimentology, logging geology, development geology. Based on lithology, physical properties, micro-pore analyzing reservoir character, the paper evaluates reservoir comprehensively and predicts promising reservoir area, which provides scientific geological proof for establishment of development plan. It can be concluded that this paper summarizes a set of method of reservoir modeling and comprehensive evaluation about low permeability reservoir, and also provides research method and route for the same kind of reservoir.
