Description

Multi-functional sump oil sewage recycling and processing device

Technical field: the utility model relates to the device of the profit of a kind of ground sump oil sewage that can receive and recycle the oilfield downhole operation working-yard and the ejection of well inner sleeve.

Background technology: sump oil and sewage that oilfield downhole operation produces flow to ground, serious pollution the environment of operation, influence operating personnel's works better, polluted soil on every side simultaneously again.There is the shortcoming of function singleness in existing sump oil waste disposal plant.

The utility model content: the utility model provides a kind of multi-functional sump oil sewage recycling and processing device, and it has solved sump oil and sewage pollution problem of environment that oilfield downhole operation produces.Multi-functional sump oil sewage recycling and processing device of the present utility model includes water-and-oil separator, the recovery pump 1 of income ground sewage, absorb the feed line 2 of oil well casing ejection profit, entrance gate 3, tubing string is carried out the test pump 4 of pressure testing with the water in the water-and-oil separator, with the re-injection pump 6 of the produced-water reinjection in the water-and-oil separator to the production main line, what the water outlet that reclaims pump 1 connected water-and-oil separator once removes grease chamber 5, entrance gate 3 is arranged on the feed line 2, the inner of feed line 2 is arranged on once and removes in the grease chamber 5, and test pump 4 is arranged on a side of the fine filtering chamber 13 of water-and-oil separator.The principle of work of this multi-functional sump oil sewage recycling and processing device is: in the sump oil sewage income auto levelizer that well head sprays and spoils over out when at first borehole operation being constructed: income method one is with self-sealing blowout preventer control oil jacket annular space, with the blowout of down-hole switch control tubing string, like this, the profit of sleeve pipe ejection can directly enter water-and-oil separator by feed line 2 during rountrip; Method two is that the sump oil sewage that flows to ground when spraying and spoiling over ground and wax removal is guided to low-lying place, takes in the water-and-oil separator with reclaiming pump 1.Secondly, sump oil sewage in the well income auto levelizer is carried out separating treatment, get rid of water quality up to standard, reclaim crude oil: watch-keeping cubicle, strainer chamber, current-sharing chamber, secondary that oily(waste)water enters in the water-and-oil separator successively remove grease chamber, smart filter chamber; Close discharge control valve, liquid level constantly rises, and oily(waste)water removes in the grease chamber in one-level, and through the catalyst action breakdown of emulsion, heavy under water, oil rises, poly-again breast; Oily(waste)water removes the grease chamber through strainer chamber, current-sharing chamber, secondary is removed part crude oil, under pressure, separate the oil of removing and flow to one-level except that the grease chamber, removed, flow to oil groove or pack other containers into by oil removal machine by the thrust-augmenting nozzle that strainer chamber and secondary remove the top, grease chamber; The remaining water that contains small part oil enters smart filter chamber, by filtrates such as gacs, removes sulfide, phenol, oil in water emulsion, and the oil base in this moment sewage originally is removed, and opens the water quality that the discharge control valve discharging removes and reaches national farmland two class emission standards.The 3rd, for oil well, the sump oil produced-water reinjection can be produced main line, do not need sewage is handled, the gate of closing control chamber after depositing certain sump oil sewage in the device, pumps into the oil well main line with re-injection pump 6 with sump oil sewage.The 4th, the test pump that utilize to be equipped with can carry out pressure testing, discharges, and beats to give up etc., can keep a certain amount of treated water in the device, and 4 pairs of tubing strings of available test pump carry out pressure testing, and release is beaten and given up, even suppresses pipe etc.Install to serve as in addition and connect oil tank and tank, convenient production, raising work efficiency.Multi-functional sump oil sewage recycling and processing device of the present utility model integrates various functions, the sump oil sewage of ejection and reclaim the sump oil sewage that falls earthward in can received well, with the sump oil produced-water reinjection production trunk line in the oil well, can carry out separating treatment to the sump oil sewage in the well again, make water quality reach the farmland emission standard; Can the instead of part water tanker, can suppress the tubing string pressure testing again, and be furnished with lagging facility.It has thoroughly solved sump oil and sewage pollution problem of environment that oilfield downhole operation produces, and has the advantage of complete function.
