According to the method and the device, various process technical units are modularized, so that the requirement of no impact on a sewage system after simple treatment can be met, and higher-end requirements of discharging, zero emission and the like can also be met.
Description
Technical field
The utility model relates to oilfield chemical technology field, refers to especially a kind of fracturing outlet liquid treatment unit.
Background technology
Since entering 21st century, low-permeability oil gas reservoir just becomes one of most important field of exploratory development, data shows, low-permeability oil deposit has accounted for the more than 1/4th of oil gas proven reserve then, both domestic and external facts have proved " waterfrac treatment is the irreplaceable technology of present stage exploitation low-permeability oil gas reservoir ".In following shale gas performance history, fracturing technique is one of key factor of restriction shale gas exploitation equally.Fracturing technique application is wider, and the fracturing outlet liquid of generation is just more, and the processing of fracturing outlet liquid has become the yoke of restriction fracturing technique development.The quantity of domestic annual fracturing outlet liquid is in 2,000 ten thousand side left and right, because the different pressure breaks requirements of every mouthful of fractured well are different, some well pressure break scale is large, some well pressure break small scale, but the scale of the fracturing fluid recovery (backflow) liquid of looking into the future annual from the direction of newly-increased exploitation oil gas block and shale gas exploitation is by increasing, and this processing demands that also means fracturing fluid recovery (backflow) liquid is by increasing.
At present, domestic still do not have a kind of complete, the technical finesse fracturing outlet liquid that can Gong apply.
Summary of the invention
The purpose of this utility model is to propose a kind of sledge-borne type fracturing outlet liquid treatment unit, to solve by various Technologies are unit-modularized, both can meet simple process and reach the requirement of not impacting sink drainage, and also can meet the technical problem that more high-end outer row and zero release etc. require.
The utility model object is to realize by such technical scheme:
A treatment unit, is comprised of four basic technology unit, comprising: well head processing unit, pretreatment unit, film processing unit and evaporation process unit; Each unit becomes separately sledge, according to fracturing outlet liquid different in kind, and collocation packaging technology route.
Operating location with focus on the nearer situation in place, after processing, sewage can effectively reduce under the condition of the impact of joint station Sewage treatment systems, technique unit collocation type of attachment is: well head unit+pretreatment unit.
After processing, qualified water can be discharged on the spot, and after processing, dope need to be transported under the condition that focuses on place, and technique unit collocation type of attachment is: well head unit+pretreatment unit+film processing unit.
Technique unit collocation type of attachment is: well head unit+evaporation process unit.
According to zero emission requirement, technique unit collocation type of attachment is a kind of in following: well head unit+pretreatment unit+evaporation process unit, well head unit+pretreatment unit+film processing unit+evaporation process unit.
The utility model possesses and has following features:
One, technique is unit-modularized, according to coming fluidity matter and processing requirements different, and the technique unit of can arranging in pairs or groups flexibly, after processing, sewage both can enter system, also can arrange outward, or realize zero release.
Two, level of automation is high, adopts a whole set of PLC to control, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is that the utility model technique unit forms and general flow chart.
In figure, number: 1, equalizing tank 2, chemicals dosing plant 3, pretreatment unit 4, plate filter 5, membrane treatment appts 6, evaporating.
Embodiment
Fracturing outlet liquid treatment unit described in the utility model, is comprised of four basic technology unit, comprising: the well head processing unit, pretreatment unit, film processing unit and the evaporation process unit that at least comprise the equalizing tank composition of taking in fracturing outlet liquid; Each unit becomes separately sledge, according to fracturing outlet liquid different in kind, and collocation packaging technology route.Operating location with focus on the nearer situation in place, after processing, sewage can effectively reduce under the condition of the impact of joint station Sewage treatment systems, technique unit collocation type of attachment is: well head unit+pretreatment unit.After processing, qualified water can be discharged on the spot, and after processing, dope need to be transported under the condition that focuses on place, and technique unit collocation type of attachment is: well head unit+pretreatment unit+film processing unit.Technique unit collocation type of attachment is: well head unit+evaporation process unit.According to zero emission requirement, technique unit collocation type of attachment is a kind of in following: well head unit+pretreatment unit+evaporation process unit, well head unit+pretreatment unit+film processing unit+evaporation process unit.
First fracturing outlet liquid is cushioned in the interior adjusting of equalizing tank 1, after chemicals dosing plant 2 dosings, at pretreatment unit 3, carry out pre-treatment, pretreated sewage filters out solid impurity by plate filter 4, then enters SUPPER RO film processing system 5, and the water after processing meets reuse or arranges requirement outward.At the dense water of this generation, deliver to evaporation process 6, in this stage, water evaporates at evaporator room, at condensing chamber, is condensed into pure water, meets reuse or arranges requirement outward, and pollutent finally forms solid crystal thing, realizes zero release.
Below in conjunction with the Fig. 1 in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
Domestic certain oil field compression fracture returns discharge opeing and processes, and after requiring to process, sewage meets national sewage second-level emission standard, allows to produce certain dense water.
This Oil Field possesses well head unit (choke manifold, sand separator, three-phase test separator, torch, crude oil burner etc.), and design agents technique is divided into two basic technology unit: pretreatment unit, film processing unit, each unit becomes separately sledge.Operational path, for the fracturing outlet liquid first well head unit being come cushions in equalizing tank, is then pumped to one-level pretreatment stage by supplied materials, and pre-treatment comprises the technology such as coagulation, flocculation, filtration, in the time of necessary, adds preoxidation medicament to break glue.By this section, process, return discharge opeing and reach COD clearance 30～40%, remove the object of suspended substance and oil slick, through the sewage in this stage, can meet and enter sink drainage and original system is not impacted.Through pretreated, return discharge opeing and enter second segment SUPPER RO film processing system, in this section processing, most COD, salt are trapped, and form dense water; The water COD that sees through film drops to 120mg/L and meets below outer row requirement.The dense water producing in subordinate phase, transfers to owner to be sent to other places and focuses on after collection.
