The Research of Layer System Adjustment Methods in DQY103 Block of the Low Permeability Reservoirs

Article Preview

Abstract:

In order to ease the contradiction between layers, layer system adjustment is applied in oilfield development and separated layer water flooding is realized better. This method is a major adjustment measure to improve development effects. DQY103 is a typical low-permeability oilfield and physical property is poor. Many problems are existed, such as apparent contradiction between layers, and poor development effects and so on. In this article, the physical property and thickness of barrier, injection profile, permeability contrast and remaining oil distribution are analyzed comprehensively. A reasonable method is also proposed. Much weakness which exists in the former methods is overcome. For example, factors are not comprehensive and accurately reflected. Poor thin layers are produced better. Invalid water injection and contradiction between layers are decreased. Development effects are improved eventually. It is a reference and guidance for other blocks which exists the same problem.
