System of oil field development with maintaining reservoir pressure

Abstract

The principles of maintaining reservoir pressure by different methods of water-flooding operation, including dispersed injection water-flooding system are considered. The technology dispersed injection water-flooding system and principles 4, 5, 7 and 9-spot dispersed injection systems are described. Attention is paid to the advantages and disadvantages of existing dispersed injection water-flooding system. Based on the analysis of technical and techno-economic performance of different water-flooding it may be concluded that the oil fields of the middle carboniferous shall be developed using dispersed injection water-flooding system. When dispersed injection water-flooding system should be considered particularly effective use of the method of labeled substances - indicators - when each is surrounded by producing wells injection. The appearance of water in production wells in this case can be attributed to its approach from any of the neighboring injection wells. If injection surfactant solution of surfactant water flooding is advisable to rather dense grid of holes. Application of surfactant solution in the system of water-flooding in multi-layers with complex inhomogeneous structure of the reservoir has a relatively low technical and economic efficiency. Most coverage is achieved with the reservoir system dispersed injection water-flooding system. As a result, the obtained distribution function elements in size were used to determine the quantity of oil, depending on the density of the grid holes.
