Description
Technical Field
The invention belongs to the technical field of oilfield sewage treatment, and particularly relates to an air floatation synergistic oil-water separation treatment device.
Background
With the continuous deep development of various large oil fields, the water content of the oil well is continuously increased, and the development and station building mode in the early stage of low water content is not suitable for the high-water-content oil production mode. For the ultra-high water content oil field with the increase of the remote block oil field or the produced liquid year by year, the oil production sewage needs to be conveyed in a centralized way in a long distance, and the problems of high energy consumption, high treatment cost, incapability of guaranteeing water quality and the like exist. In order to overcome the limitations of the pre-diversion facilities of the existing gathering, transportation and output liquid treatment system, an in-situ diversion treatment device of an oil field with high efficiency, small occupied area and low investment is needed. At present, "in-situ water diversion and in-situ reinjection" has become a main means for improving economic benefit of high-water-content oil fields, and especially, a short-process treatment technology for pre-diversion of short, small and fine oil fields has become an urgent need for simplifying the process, saving investment and reducing energy consumption and running cost of the high-water-content oil fields.
The prior pre-water separation equipment mainly comprises a hydrocyclone, a cavity barrel separator, an inclined tube pre-water separator, a three-phase separator, a multifunctional crude oil treatment combination device, a full-gravity balance oil-gas-water treatment integrated device and an integrated pre-water separator. Most of the current pre-water devices involve only one or a few technologies, and the goals of in-situ water diversion, in-situ treatment and in-situ reinjection cannot be achieved by using the pre-water devices alone.
The operation technology is known to be mainly two, namely a three-phase separator and pressure oil remover technology and an integrated short-flow on-site water diversion technology, wherein the two on-site water diversion technologies can meet the field process requirements, but the integrated short-flow on-site water diversion technology mainly has the defects of complex process and high maintenance cost, and the three-phase separation and oil remover technology mainly has the defects of long flow and unstable water quality. Therefore, the water quality is required to be designed according to the space in the station and the water quality requirement.
At present, three-phase separator equipment is generally adopted for pre-diversion in domestic oil fields, the oil content index of the separated sewage is higher, and a conventional sewage treatment system is required to be constructed in a matched manner, wherein the typical process flow comprises 'high-water-content produced liquid, pre-diversion device, oil removal tank, settling tank, air floatation, buffer tank, lift pump, filter, fine filter and water outlet'. The sewage treatment process flow is complex, the integration and skid-mounted are not realized, the occupied area is large, the investment is high, the process simplification requirement cannot be met, and the separated sewage is basically conveyed to a joint station for treatment, so that the targets of on-site water diversion, on-site treatment and on-site reinjection cannot be realized. In order to overcome the limitation of the pre-diversion facilities of the existing gathering and transportation and produced fluid treatment system, an in-situ diversion treatment device of the oil field with high treatment efficiency, small occupied area and low investment is needed.
