Abstract
The utility model discloses an electric pump oil-extracting pipe column with ground hydraulic control oil-pipe injection functions for a petroleum industry. Positive injection of various operating fluids into a shaft or a stratum can be performed through an oil pipe on an electric pump oil-extracting well, well-washing operation is performed, and an electric pump cable is protected. The pipe column comprises an electric pump oil-extracting portion, a subsurface safety valve and an annulus packer, a hydraulic control sliding sleeve is connected between the lower portion of the annulus packer and the electric pump oil-extracting portion, opening and closing of the hydraulic control sliding sleeve are controlled through a sliding sleeve hydraulic control pipeline, and the function of injecting the operating fluids into the well through the oil pipe is achieved. The electric pump oil-extracting pipe column can achieve the functions of stratum deblocking, chemical paraffin removal, well washing, shaft fault seeking and the like. Compared with a traditional pipe column, the electric pump oil-extracting pipe column can carry out large-displacement squeeze injection operation, reduces injection pressure, protects the cable, prolongs an overhaul cycle, and has remarkable economic benefit.
Description
Technical field
The utility model relates to the down-hole oil production tubing string of petroleum industry electric pump producing well; Particularly ground hydraulic is controlled the electric motor drive oil pump system tubing string of oil pipe function of injecting; Can just annotate various hydraulic fluids through oil pipe to pit shaft or stratum in that electric motor drive oil pump system is aboveground, carry out clean-out service, protection electric pump cable.
Background technology
The submersible electric pump DP technology is widely used in each elephant, is mechanical oil recovery a kind of DP technology technology, particularly offshore oilfield commonly used, and little because of the space, convenient management has unique advantage.The offshore oilfield submerged electric oil pump well is because the safety and environmental protection requirement need be lowered to storm valve and annular space packer; When emergency is arranged,, close the outlet valve on storm valve and the annular space packer through the liquid controling pipe line pressure release; Realize urgent closing well, guarantee marine Environmental Safety
.If carry out clean-out service, also be in the oil jacket annular space, to inject various hydraulic fluids through the outlet valve on the annular space packer.But the outlet valve latus rectum on the annular space packer is less, if inject liquid through outlet valve to the down-hole, can cause and inject difficulty, and cable is caused damage because the throttling reason causes down-hole pressure to raise.The cable of electric pump producing well costs an arm and a leg, and the cable fault meeting causes enormous economic loss, therefore, needs a kind of electric motor drive oil pump system tubing string with oil pipe function of injecting of exploitation, the protection cable.
Summary of the invention
The purpose of the utility model provides the electric motor drive oil pump system tubing string of ground hydraulic control oil pipe function of injecting; Can control at ground hydraulic, realize injecting the function of various hydraulic fluids, protection electric pump cable to the big discharge capacity in stratum through oil pipe; Working service is convenient, reduces production costs.
The purpose of the utility model is achieved in that the electric motor drive oil pump system tubing string of ground hydraulic control oil pipe function of injecting comprises electric motor drive oil pump system part, storm valve and annular space packer; Storm valve is connected with the ground hydraulic switch board with the packer liquid controling pipe line through the safety valve liquid controling pipe line respectively with the annular space packer, and storm valve, annular space packer partly are connected through oil pipe with electric motor drive oil pump system.Also be connected the hydraulic control sliding sleeve below the annular space packer with between the electric motor drive oil pump system part, and be connected with the ground hydraulic switch board through the sliding sleeve liquid controling pipe line.With the opening and closing of sliding sleeve liquid controling pipe line control hydraulic control sliding sleeve, realize in well, passing through the function that oil pipe injects hydraulic fluid.
Compared with prior art the utlity model has following useful effect: the utility model is through the opening and closing at Ground Control hydraulic control sliding sleeve; Realization is injected working solution continuously from the big discharge capacity of oil pipe; Avoided injecting fluid from annular space packer outlet valve; Because of the high pressure damage cable that throttling forms, protected cable effectively, reduced cost of production.Through injecting fluid from the big discharge capacity of oil pipe, make various underground work constructions, easy to operate like acidifying, de-plugging etc., the production capacity of efficient recovery oil well can be arranged.When also making things convenient for electric pump well to break down simultaneously, search analyzing failure cause, make the science countermeasure through injecting fluid to pit shaft.Utilize this electric motor drive oil pump system tubing string can realize removal of bridge formation, paraffin removing with chemical method, well-flushing, search functions such as borehole failure, compare, can carry out the operation of big discharge capacity squeeze note with traditional tubing string; Reduced injection pressure; The protection cable prolongs the time between overhauls(TBO), has tangible economic benefit.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing; The electric motor drive oil pump system tubing string of ground hydraulic control oil pipe function of injecting comprises electric motor drive oil pump system part, storm valve 1 and annular space packer 2; Storm valve 1 is connected with the ground hydraulic switch board with packer liquid controling pipe line 10 through safety valve liquid controling pipe line 9 respectively with annular space packer 2, and storm valve 1, annular space packer 2 partly are connected through oil pipe with electric motor drive oil pump system.Also be connected hydraulic control sliding sleeve 3 below the annular space packer 2 with between the electric motor drive oil pump system part, and be connected with the ground hydraulic switch board through sliding sleeve liquid controling pipe line 11.Hydraulic control sliding sleeve 3 comprises hydraulic cylinder, outer tube and interior pipe, is equipped with liquid flow hole on outer tube and the interior pipe, and interior pipe box is contained in the outer tube, and hydraulic cylinder is installed in the top of outer tube, and sliding sleeve liquid controling pipe line 11 is connected with hydraulic cylinder.
Oil well can inject fluid through the utility model in well, like de-plugging agent, flushing fluid etc.During the oil well ordinary production, hydraulic control sliding sleeve 3 is closed.In the time of need in well, injecting fluid, suppress through sliding sleeve liquid controling pipe line 11 on ground, make the hydraulic cylinder piston of hydraulic control sliding sleeve 3 promote in pipe move with outer tube on liquid flow hole overlap unlatching hydraulic control sliding sleeve 3.Fluid injects from oil pipe, through storm valve 1, gets into the tubing and casing annular space from hydraulic control sliding sleeve 3, thereby gets into oil reservoir.After injecting the construction completion, through 11 pressure releases of sliding sleeve liquid controling pipe line, the interior pipe of hydraulic control sliding sleeve 3 and the liquid flow hole on the outer tube are staggered, close hydraulic control sliding sleeve 3, also just closed the passage between oil pipe and the sleeve pipe, recover normal oil recovery state on ground.
