Development And Application Of Fast-Assembling Polymer Injection Device

In recent years, with the development of land oil reservoirs, many oil field, both domestic and international, entered into their mid and later stage. Representing more and more difficulties of development, these oil field can hardly maintain their past oil production, the traditional development type has reached a limit. Under this background, with the application of tertiary oil recovery injection devices, their function of enhanced oil recovery is becoming increasingly remarkable. Polymer flooding is an advanced and widespread tertiary oil recovery technology, but there are some problems in it. For this reason the thesis is carried out researchBeginning with the narration of domestic and international tertiary oil recovery development, this thesis introduces the function and compositions of each component of tertiary oil recovery polymer injection device. By studying the performance and parameter, obtain a series of design, technology selection, operation and control theories. Devise a set of connecting method and control program which can able to make each module not only work efficiently but also cooperate well. For future tertiary oil recovery projects provide theoretical basis that contain design, technology selection, installation, automatic control and so on.Finally, this thesis demonstrate the feasibility of increasing production by introducing well operation of several polymer injection stations in Dagang Oilfield,.
