"Hydrodynamic" Drives Benefit Oil
The third oil production plant of Dagang Oilfield strengthens fine water injection, uses "hydrodynamic" to drive benefit oil, and effectively controls the output decline. At present, the daily oil production of water injection development in the third oil production plant is rising steadily, and the development index continues to improve.
The third oil production plant gives full play to the advantages of water injection development, and makes intensive cultivation in water injection development deployment, quality mode, quality management and process regulation, so as to ensure good water injection, sufficient water injection and effective water injection. For water flooding reservoir homogeneity, the same reservoir development effect difference, technical personnel to strengthen basic research, promote water injection work to achieve "five changes", namely by the comprehensive water injection to optimize the water injection, from multilayer water injection to effective layer injection, from a single medium water injection to combination medium injection, from straight well to flat combination injection and production, from synchronous injection to asynchronous injection.
The third oil production plant built a dynamic automatic warning software platform for water injection in Wangguantun Oilfield, and took measures such as asynchronous injection and injection, coupled water injection, rotation control in different directions, and correlation and interactive deployment, which reduced the natural decline rate of extremely high water-bearing reservoirs such as Guan 3 and Guan 80. Three oil production plant for different reservoir characteristics, according to the mainstream line, the mainstream line distribution, strengthen the direction, deformation under the seepage network, precise subdivision, well network, water injection dynamic deployment, variable strength water injection, injection-production ratio optimization, point weak surface strong water injection combination, reduce the natural decline rate of reservoir.
