2drive oil recovery ground to inject supporting flow process in-site installation and adopt traditional mode always, the station fixed CO in field is installed
2storage tank, plunger type injection pump, canned motor pump, add magnetic heater, measuring instrument and electric power equipment.CO
2storage tank is connected flow process because of distance with canned motor pump and canned motor pump with plunger type injection pump, and elbow is many, and throttle point causes liquid CO more
2tank is gone out to before entering canned motor pump and liquid CO from storage tank
2liquid CO is there is when canned motor pump out enters plunger type injection pump
2gasification phenomenon, causes centrifugal canned motor pump and plunger type injection pump normally to run.Fixed CO simultaneously
2gas-injection station, field device flow process of standing is all fixing, migrates to other a bite well note CO at needs
2time, field device and the technological process demolition work amount of standing is large, and existing processing pipe network flow process cannot directly apply to another field, station substantially, and need again pipe arrangement to install, field device of stand migration complex procedures is heavy, and expense is paid higher.
Utility model content
The purpose of this utility model is to provide a kind of skid-mounted type CO being applicable to applying working condition
2injection device, overcomes the liquid CO that above-mentioned prior art exists
2easy gasification, field device of standing migration complex procedures is heavy, the defect that expense expenditure is higher.
The technical solution of the utility model is achieved in the following ways: the utility model is by CO
2storage tank and sled block on install canned motor pump, low temperature plunger displacement pump, mass flowmenter, electromagnetic heater, power set composition, import and the return line of canned motor pump are connected to CO
2storage tank, shielding delivery side of pump is connected by pipeline with the import of low temperature plunger displacement pump, and low temperature plunger delivery side of pump is through threeway, and the return line of low temperature plunger displacement pump of leading up to is connected to CO
2storage tank, another road, as injection pipeline, is injected on pipeline and is provided with mass flowmenter and electromagnetic heater; Power set comprise frequency-variable controller and temperature controller, and wherein frequency-variable controller is connected with low temperature plunger displacement pump, and temperature controller is connected with electromagnetic heater.
The beneficial effects of the utility model are that process layout is reasonable, and equipment room is apart from short, and flowage structure is succinct, without throttle point, effectively avoids CO
2go out tank easily to gasify and cause pump group fallback problem, improve work efficiency, by field, station environmental constraints, and plant investment is few, takes up an area few, easy for installation, and easily migration, running cost are low, are convenient to large-scale promotion.
