The main parameter of the quality of the injected reservoir water, which has an impact on reducing injectivity of injection wells, is the concentration (content) of oil and solidparticles (SP). In conditions of high load of well production preparation objects is not always possible to achieve these requirements. On Majachnye field of workshop oil and gas №5 there are certain problems. In addition, in the field there are well clusters, producing high water cut products. It increases the economic costs of transportation and preparation ofoil emulsion. In this regard, the issues of improvement of produced water quality for injection, the reducing the load of in-field training facilities and the reduction of transportation costs and the destruction of oilemulsion becomes more urgent. This paper presents a solution - Cluster technology of preparation and injection of produced water from wells into the reservoir using a pipe phase divider.
Materials and methods
Process data from the field, the published data, analysis.
Results
According to the results of scientific and technical analysis of the proposed technology with the use of pipe phase divider expedient and economically feasible. The result of the technology is to reduce transport costs and product preparation costs, as well as in the repair of pipelines.
Сonclusions
1. In order to achieve water quality according to the enterprise standard for injection into the reservoir pressure maintenance system (oil content - 28 mg / l, solid content -19 mg / l) taken in the design characteristics of the pipe phase divider can be considered satisfactory.
2. Potential 74% plant capacity exceeds the total intake capacity of injection wells of the Mayachniy field that determines the headroom for wells planned to be converted into injector wells.
