Skid-mounted modularized polymer-surfactant binary drive injection allocation device applicable to complex fault block oil field

Abstract

The invention discloses a skid-mounted modularized polymer-surfactant binary drive injection allocation device applicable to a complex fault block oil field and belongs to the technical field of tertiary oil recovery. According to the skid-mounted modularized polymer-surfactant binary drive injection allocation device applicable to the complex fault block oil field, a moveable produced water deeptreatment module, a moveable polymer dry powder dispersion module, a moveable auxiliary agent addition module, a moveable polymer mother liquid on-line aging module, a moveable feeding module, a moveable surfactant storage dilution and addition module and a moveable injection module are sequentially arranged at the liquid inlet end and the liquid outlet end of a first pipeline, a moveable power supply and distribution and automation control module is arranged at the liquid inlet end of the first pipeline, then power support and automatic control are provided for the modules, a standardized andmodularized polymer injection binary drive injection allocation device is established, industrial manufacturing and production can be achieved, the station construction period of a polymer injectionbinary drive injection allocation station is shortened, and convenience is brought to on-site management and repeated multi-time use.

Description

technical field [0001] The invention relates to the technical field of tertiary oil recovery, in particular to a skid-mounted modular polymeter binary flooding distribution device suitable for complex fault-block oil fields. Background technique [0002] Polymer surface binary flooding is an important technology in oil field tertiary oil recovery chemical flooding. By using the synergistic effect of the ability of polymer to expand the swept volume and the ability of surfactant to reduce interfacial tension, the oil recovery rate can be greatly enhanced. The purpose is to widely popularize and apply it in various oilfields. [0003] At present, there are two setting modes for the injection unit of the meter-based binary flooding: one is the fixed mode, which is used for specific blocks by installing the unit as a whole on the well site; the other is the fixed mode. The first is the skid-mounted model, and each component can be reused. When the specified block needs to use t...

AI Technical Summary

Problems solved by technology

[0005] The fixed mode in the existing assembly device of the combined meter dual drive can not be moved for repeated use, which occupies a large area and has high investment costs; the equipment integration degree of the skid-mounted mode is not high, and the area is also large, and it is difficult to build a station. The cycle is long and inconvenient to manage. For some complex fault-block oilfields, there are many types of reservoirs, small and scattered development blocks, complex ground conditions, many points and wide areas, etc., which are not suitable for injection with a large area device
