Abstract
The utility model relates to a movable device for paraffin removal and washing of an oil well with a primary well fluid. The movable device adopts the technical scheme that a heating device (2) is arranged in a movable heating device (1), a primary well fluid guide pipe (3) is arranged at the upper part of one end of the heating device (2) and butted with a valve reserved on an oil pipe (10), a primary well fluid reinjection pipe (4) is arranged at the lower part of the other end of the heating device (2) and butted with a valve reserved on a casing pipe (9), a sucker rod (5) connected with an oil pumping unit (8) extends to the lower part inside the oil pipe (10) through the ground (6) and the casing pipe (9), and the casing pipe (9) extends into the strata (7). Through the adoption of the structure, the movable device reduces the downtime of paraffin removal, saves the consumption of energy and water resources, avoids the pollution to the oil layer, greatly increases the output of a single well, and is suitable for popularization and application.
Description
Technical field
The utility model relates to paraffin removal from oil well, washing technology field, is specifically related to a kind of original well liquid that uses to the mobile unit of oil well wax removal, well-flushing.
Background technology
In oil exploitation, run into the high oil well of the content of wax, the solid that often can congeal into occurs not fuel-displaced or card well phenomenon.What adopt now is to use outer thermal source, and hot water, steam or chemicals are injected into the down-hole, and wax is melted, and then the start discharge opeing, and discharge opeing will have the time about 3 days, has not only polluted oil reservoir, also has a strong impact on the crude oil production capacity.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, and the mobile unit of a kind of simple in structure, with low cost, use original well liquid of not needing discharge opeing to oil well wax removal, well-flushing is provided.
Its technical scheme is: comprise sucker rod, ground, stratum, oil pumper, oil pipe, portable firing equipment, heater, original well liquid ingress pipe, original well liquid re-injection pipe and sleeve pipe; Be provided with heater in the portable firing equipment, heater one end top is provided with the original well liquid ingress pipe and docks with reservation valve on the oil pipe, one end bottom is provided with original well liquid re-injection pipe and docks with reservation valve on the sleeve pipe, the sucker rod that oil pumper connects extends into the below, inside of oil pipe through ground and sleeve pipe, sleeve pipe stretches in the stratum, and portable firing equipment is installed in the compartment of automobile.
After adopting said structure, reduced wax removal downtime, saved the energy, water resources consumption, polluted reservoir has not increased substantially well yield, is fit to generally promote the use of.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
As shown in the figure, use original well liquid to the mobile unit of oil well wax removal, well-flushing, comprise sucker rod 5, ground 6, stratum 7, oil pumper 8, oil pipe 10, portable firing equipment 1, heater 2, original well liquid ingress pipe 3, original well liquid re-injection pipe 4 and sleeve pipe 9; Be provided with heater 2 in the portable firing equipment 1, heater 2 one end tops are provided with original well liquid ingress pipe 3 and dock with reservation valve on the oil pipe 10, one end bottom is provided with original well liquid re-injection pipe 4 and docks with reservation valve on the sleeve pipe 9, the sucker rod 5 that oil pumper 8 connects through ground 6 and sleeve pipe 9 extend into the below, inside of oil pipe 10, sleeve pipe 9 stretches in the stratum 7.
Portable firing equipment 1 is installed in the compartment of automobile, move near the well head, reserve valves from oil pipe 10 and pick out Yi Tiaolu, the liquid that this well is extracted out the heater 2 of flowing through is reserved valves at sleeve pipe 9 again and is docked current return circuit, make original well liquid body after the heating through the gap of sleeve pipe 9 and oil pipe 10, get back to undergroundly, the oil pipe 10 of heating wax deposition melts wax deposition and flows out with oil well liquid, oil pumper runs well, and liquid outlet quantity is recovered rated value.After finishing the wax removal operation, valve-off, production restoration is normal.
Claims (2)
1. use original well liquid to the mobile unit of oil well wax removal, well-flushing, comprise sucker rod (5), ground (6), stratum (7), oil pumper (8), oil pipe (10), it is characterized in that: also comprise portable firing equipment (1), heater (2), original well liquid ingress pipe (3), original well liquid re-injection pipe (4) and sleeve pipe (9); Be provided with heater (2) in the described portable firing equipment (1), described heater (2) one end tops are provided with original well liquid ingress pipe (3) and dock with the upper valve of reserving of oil pipe (10), one end bottom is provided with original well liquid re-injection pipe (4) and docks with the upper valve of reserving of sleeve pipe (9), (6) and sleeve pipe (9) extend into below the inside of oil pipe (10) sucker rod (5) that described oil pumper (8) connects through ground, and described sleeve pipe (9) stretches in the stratum (7).
