The Detailed Reservoir Geological Research Of Block Jin 610

For there is no systematic study since Jin 610 has been put into the development, blocks existed some problems like unreasonable stratigraphic correlation and structure analysis, deposition rule, reservoir characteristics and the relationship between water and oil, which serious restricted the adjustment measures implemented late development, resulting in the gradual deterioration of the block development results, up to now halted.To reconstruct the underground system, restore block production capacity. By using the integrated application of drilling and completion, logging and development of dynamic data, stratigraphic correlation and division, fine structural interpretation, reservoir evaluation, heterogeneity description, logging the second interpretation, geological construction mold and other technical means, finished the stratigraphic division, fracture characteristics, structural morphology, deposition rule, reservoir characteristics and distribution of water and other in-depth study and interpretation by logging twice to re-establish an effective thickness of the criteria for the classification, determine the reserves calculation parameters, reserves were re-counted in Jin 610. Based on the establishment of a three-dimensional block reservoir parameters geological model, this paper visualized the structural characteristics block, reservoir properties and reservoir distribution.The results show that the Yulou and Xinglongtai oil reservoirof Jin 610 are divided into two groups and six zones, structural form is broken nose structure slope background, developmental five faults; coarse- silt sandstone reservoir lithology with pebbly, controlled by sedimentary facies and sand body distribution from north west to south east direction overall thinning, moderate clay content; reservoir properties of high porosity and permeability; room flat, strong heterogeneity, heterogeneity within the layer "medium-weak". Water distribution is mainly controlled by faults, the high parts of the oil concentrate development are composite bulk longitudinal characteristics, block low-water interaction between distinct parts. the upper floor of the reservoir is thin to medium(thick) interbedded bottom edge water reservoir, the lower reservoir Xinglongtai interbedded thin to medium edge and bottom water reservoir. Block crude nature of conventional heavy oil, formation water of the type of NaHCO3 type, temperature, pressure systems were normal temperature, pressure systems.
