Abstract
The utility model belongs to the technology field of cleaning and recovery in oil field operation, and particularly relates to an oil dirt resisting device for an operation well head. Conventional oil liquids recovered from a polluted oil pool is recovered by the aid of a sewage suction vehicle, the recovery period is long, the cost is high, and serious safety hidden trouble is left due to the polluted oil in the polluted oil pool in a long term. In order to overcome the above mentioned defects, the technical scheme adopted is: the oil dirty resisting device for an operation well head is characterized in that: the oil dirty resisting device comprises an oil connector, a pipe string, and an oil leakage backflow opening, the outlet of the oil collector and the well head are in a sealed connection, the axis position of the oil collector is provided with the pipe string, the pipe string is connected with the bottom of the oil collector; an oil pipe is disposed in the pipe string, the oil leakage backflow opening is disposed on the pipe string at the position of the bottom of the oil collector. The oil dirt resisting device in the utility model can conveniently and automatically recovering leak oil in operation process, and prevents pollution and safety hidden trouble caused by incapability of timely cleaning of well head due to oil leakage.
Description
Technical field
The utility model belongs to oil field operation leakage of oil technology for cleaning and recovering field, relates in particular to the grease proofing dirty device of a kind of operation well head.
Background technology
In the oil well operation; pump detection and workover is absolutely necessary; situation causes bleeder not opened but sediment is too much in regular meeting runs into disconnected bar, pump seizure or pump in pump detection and workover etc.; the oil pipe inner fluid can be mentioned when playing the production post in the lump at this moment; fluid when oil pipe proposition well head is turned on screw thread in the oil pipe will outflow; inconvenience is reclaimed, and the fluid of outflow not only causes certain pollution to well head and surrounding enviroment, and has brought huge potential safety hazard to construction.If the moisture height of fluid of outflow, can flow into contaminated-oil basin by oil guide groove smoothly, as low moisture or oil-water emulsion, then need the labor cleaning, and the fluid that reclaims contaminated-oil basin also needs to reclaim by suction-type sewer scavenger, return period is long and with high costs, and contaminated-oil basin has sump oil for a long time and has serious potential safety hazard.
Summary of the invention
The purpose of this utility model provides a kind of well head greasy dirt that can reclaim automatically and pollutes the grease proofing dirty device of operation well head of inconvenience cleaning to prevent well head.
To achieve these goals, the technical solution adopted in the utility model is:
The grease proofing dirty device of a kind of operation well head is characterized in that: comprise oil trap, and tubing string, the leakage of oil reflux opening, the outlet and the well head of described oil trap are tightly connected, and the axial location of oil trap is provided with tubing string, and tubing string is connected with the bottom of oil trap; Oil pipe is set in the tubing string, on the position tubing string of oil trap bottom, the leakage of oil reflux opening is set.
Above-mentioned leakage of oil reflux opening is set to 1-6,
Above-mentioned oil trap is arranged to infundibulate.
Compared with prior art, the utility model beneficial effect is as follows:
The utility model can reclaim the leakage of oil in the operation process easily automatically, prevent well head because pollution and the potential safety hazard that causes can not be in time cleared up in leakage of oil, not only reduce the labour intensity of operating worker, reduced pollution, can also reduce the generation probability of security incident greatly.
Description of drawings
Fig. 1 is the grease proofing dirty apparatus structure schematic diagram of operation well head,
Wherein, 1-oil trap, 2-tubing string, 3-oil pipe, the outlet of 4-oil trap, 5-leakage of oil reflux opening.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, the grease proofing dirty device of a kind of operation well head, it is characterized in that: comprise oil trap (1), tubing string (2), leakage of oil reflux opening (5), the outlet of described oil trap (4) is tightly connected with well head, and the axial location of oil trap (1) is provided with tubing string (2), and tubing string (2) is connected with the bottom of oil trap (1); Oil pipe (3) is set in the tubing string (2), on the position tubing string (2) of oil trap bottom leakage of oil reflux opening (5) is set, described leakage of oil reflux opening (5) is 1-6, and described oil trap (1) is an infundibulate.
Residual fluid can outflow in oil well operation process oil pipe 2, when perhaps bleeder is not opened in the pump detection and workover, oil pipe 2 inner fluids also can outflow when oil pipe 2 is turned on screw thread, this moment, oil spill in operation can flow into the oil trap 1 of the grease proofing device of operation well head, because on the tubing string 2 of oil trap 1 bottom position, leakage of oil reflux opening 5 is set, leakage of oil promptly passes back into oil well along leakage of oil reflux opening 5, can not dye, prevent well head because pollution and the potential safety hazard that causes can not be in time cleared up in leakage of oil in the wellhead stack contamination.
Leakage of oil reflux opening 5 is set to 1-6, and when oil trap 1 oil trap (1) is the easier inflow leakage of oil of an infundibulate reflux opening, organic efficiency is higher.
Claims (1)
1. grease proofing dirty device of operation well head, it is characterized in that: comprise oil trap (1), tubing string (2), leakage of oil reflux opening (5), the outlet of described oil trap (4) is tightly connected with well head, the axial location of oil trap (1) is provided with tubing string (2), and tubing string (2) is connected with the bottom of oil trap (1); Oil pipe (3) is set in the tubing string (2), on the position tubing string (2) of oil trap bottom, leakage of oil reflux opening (5) is set.
2. the grease proofing dirty device of operation well head according to claim 1 is characterized in that: described leakage of oil reflux opening (5) is 1-6.
3, the grease proofing dirty device of operation well head according to claim 1 and 2 is characterized in that: described oil trap (1) is an infundibulate.
