Study On The Injection Production Performance And Development Adjustment Of The Bottom Water Oil Reservoir

Reservoir with bottom water reservoir in China accounted for a substantial proportion of its abundant reserves.Except the end has many natural water reservoir outside,with access to the secondary exploitation of oil fields,more oil fields to develop the characteristics of continuous trend in the type of bottom water reservoir. Subject to S to the bottom water reservoir for the object,the use of petroleum geology and reservoir engineering methods,to carry out S oil field injection-production Dynamic comprehensive study,and then put forward that would effectively improve the effectiveness of oil field development countermeasures adjust.With the constant deepening of field development,S oilfield geological understanding of the changes,especially oil-bearing area,reservoir thickness and geological reserves are major changes.Test mining production showing a formation energy is weak,single-well production decline rapidly,moisture content tended to rise.Production aquifer wells a long time high, the output low,in the East Wing of the wells constructed higher moisture content.North oil field production time tired early oil production,and injection wells at less stratigraphic big deficit; the Southern District late start time,add water energy output is relatively stable.Combination of geological research results,in view of the current oil field development of the contradictions arising in the course of,in accordance with the "results-based geological studies, reservoir engineering theory as a guide,To a comprehensive analysis of reservoir performance, reservoir simulation,economic evaluation as a means to economic and rational deployment of the optimal field development program",the technical ideas, the use of petroleum geology and reservoir engineering methods,to carry out logging quadratic field S explained that the reservoir sensitivity,wettability and flow characteristics of sedimentary facies and seismic constraints Geological Modeling technology applied research;of the test oil,the effect of the test-mining evaluation and conclusion, on this basis,the injection-production wells Net adaptability,water effects and technology policy development boundaries to do further analysis and study,eventually form a reservoir to meet the current reality,operability than strong network of injection and production wells,through the implementation of the outcome, improve and optimize the oil field injection-production system,to supplement and maintain the formation energy,the main oil sands enhance body control the degree of water flooding and water-driven by reserves,improve the speed and oilfield oilfield finally adopted yield.
