Abstract
The utility model relates to a completion pipe string of an electric pump production well in oil industry, in particular to a sand prevention completion pipe string of the electric submersible pump. The sand prevention completion pipe string of electric submersible pump comprises an electric pump oil production system, electric pump units connected with each other from top to bottom in sequence, a check valve and an oil discharger. The lower portion of the electric pump units is connected with a sand prevention device. The sand prevention device comprises a circular screen pipe, a kerf screen pipe and a riffling pipe connected with each other from top to bottom in sequence. Outer surfaces of the circular screen pipe and the kerf screen pipe are provided with packers, and an inner chamber is provided with funnel-shaped filter screen. Compared with the prior art, due to the fact that oil flow has to pass multistage filtering before entering the electric units, the sand prevention completion pipe string of the electric submersible pump has the advantages of avoiding large particles of sand entering the electric pump units, prolonging service life of the electric pump units, reducing sand prevention cost in operation and production cost.
Description
Technical field
The utility model relates to the completion tubular column of petroleum industry electric pump producing well, particularly a kind of submersible electric pump sand control completion tubing string
Background technique
The submersible electric pump oil production technology is widely used in each elephant, is mechanical oil recovery a kind of oil production technology technology commonly used, and common electric pump pipe column does not have sand control, sand-blocking function, but electric pump is comparatively responsive for sand output well.If formation sand production is slight, carry out separately sand control construction, then the activity duration long, the expense height; If sand control is not then lacked the working life of electric pump unit.Therefore, for the electric pump producing well that slightly shakes out, need a kind of electric pump well-completion pipe column with sand-blocking function of exploitation.
Summary of the invention
The utility model purpose provides a kind of reasonable in design, easy to operate, submersible electric pump sand control completion tubing string with sand-blocking function.
The purpose of this utility model realizes by following scheme: comprise the electric motor drive oil pump system system, it comprises electric pump unit, one-way valve and the oil drainer that connects successively from bottom to top; The below of described electric pump unit connects sand control installation, and described sand control installation comprises circular hole screen casing, cutting seam sieve tube and the sand sediment pipe that connects successively by oil pipe from top to bottom; Outer surface of tube wall is provided with packet between described circular hole screen casing and the cutting seam sieve tube, inner chamber is provided with the funnel-like filter screen.
Such scheme also comprises:
Described sand sediment pipe is comprised of the plug of body and bottom thereof.
Described packet is cup packer.
Compared with prior art the utlity model has following useful effect: the utility model is by being connected to the sand control installation of bottom, can make oil stream before entering the electric pump unit, must pass through multistage filtering, avoid the large particle sand to enter the electric pump unit, prolonged the working life of electric pump unit, sand control expense in the time of can reducing operation reduces production costs.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to Fig. 1, a kind of submersible electric pump sand control completion tubing string comprises the electric motor drive oil pump system system, and it comprises electric pump unit 3, one-way valve 2 and the oil drainer 1 that connects successively from bottom to top; Electric pump unit 3 is connected with ground power supply by cable 10, and its below connects sand control installation, and sand control installation comprises circular hole screen casing 4, cutting seam sieve tube 7 and the sand sediment pipe 8 that connects successively by oil pipe from top to bottom, and sand sediment pipe 8 is comprised of the plug 9 of body and bottom thereof; Outer surface of tube wall is provided with cup packer 5 between circular hole screen casing 4 and the cutting seam sieve tube 7, inner chamber is provided with funnel-like filter screen 6.Cup packer 5 packings the annular space of oil pipe and sleeve pipe, make the oil stream from oil reservoir through just entering electric pump unit 3 after cutting seam sieve tube 7, funnel-like filter screen 6 and 4 filtrations of circular hole screen casing, stop entering of large particle reservoir sand by filtration.Oil stream flows out from screen casing 4, enter oil pipe and casing annulus after, by 3 pumping of electric pump unit and process one-way valve 2 and oil drainer 1, be lifted to well head.The sand fallout that is filtered by funnel-like filter screen 6 prevents that accumulation is too much stopped up cutting seam sieve tube 7 and funnel-like filter screen 6 in the oil pipe to sand sediment pipe 8.
Claims (3)
