Abstract
A self-sealing packer is composed of a connection joint, a leather cup seat, a sealing leather cup, an inner tube and a lining. The lower part of the connection joint is connected with the upper part of the inner tube. The sealing leather cup is placed in the inner tube. The leather cup seat is arranged above the sealing leather cup and outside of the inner tube. The connection joint is provided with connection holes. The bugle mouth of the sealing leather cup is downward. The upper part is connected with the lower part of a first sided liquid input device, and the lower part is connected with the upper part of a second sided liquid input device. The sealing leather cup is against the inner wall of the lining, thus making liquid flow into the inner tube from the second sided liquid input device and flow out from connection holes of the connection joint to enter the first sided liquid input device, thus meeting the requirements f cylinder pile control flow patch of two sided oil input tools in serial connection.
Description
One, technical field
The utility model relates to the downhole packer that a kind of oil well is used, and is a kind of self-styled type packer.
Two, background technology
In oil field machinery oil, need to adopt packer control well liquid runner, make well liquid by the flow passage of designing requirement by extraction, present packer is generally mechanical packer or fluid pressure type packer, this packer of two types will apply an envelope power just can make packer set, make the weight seat envelope of tubing string, perhaps rises hydraulic base sealed in tubing string, and the flow string that has does not allow to adopt this dual mode seat envelope, as electric pump producing well.Because electric motor drive oil pump system is the side direction feed liquor, when electric pump producing well also had other side direction feed liquor instrument down, present packer just can not satisfy the requirement that series connection has the tubing string control runner of two kinds of side direction oil-feed instruments down.
Three, summary of the invention
The purpose of this utility model is a kind of self-styled type packer of design, does not need just can seal oil casing annular space to its operation, satisfies the requirement of particular oils well control system runner.
The purpose of this utility model is achieved in that by UNICOM's joint, leather cup seat, sealing cup, interior pipe, lining to be formed, UNICOM joint bottom connects with interior pipe top, sealing cup is sleeved on the interior pipe, the leather cup cover for seat is in the upper end of sealing cup, lining is placed in outside the interior pipe, and be in the sealing cup, on UNICOM's joint linked hole being arranged, the horn mouth of sealing cup is directed downwards.
The beneficial effects of the utility model are: sealing cup is close to internal surface of sleeve pipe, the horn mouth of sealing cup is directed downwards, liquid stream can not flow from the sealing cup lateral, liquid stream can only upwards be flowed out from the linked hole of UNICOM's joint from interior pipe inside again, can satisfy the requirement that the tubing string that two kinds of side direction oil-feed instruments are arranged under the series connection is controlled runner.
Four, description of drawings
Accompanying drawing is the utility model assembled view.
Five, the specific embodiment
As shown in the figure, form by UNICOM's joint 1, leather cup seat 3, sealing cup 4, interior pipe 5, lining 6, lower contact 8, UNICOM's joint 1 bottom connects with interior pipe 5 tops, manage on 5 in sealing cup 4 is sleeved on, leather cup seat 3 is enclosed within the upper end of sealing cup 4, manages outside 5 in lining 6 is placed in, and is in the sealing cup 4, linked hole 2 is arranged on UNICOM's joint 1, and the horn mouth 7 of sealing cup 4 is directed downwards.Interior pipe 5 bottoms connect with lower contact 8.UNICOM's joint 1 top is internal thread.
During use, UNICOM's joint 1 top connects with first side direction feeding device bottom, lower contact 8 bottoms connect with second side direction feeding device top, sealing cup 4 is close to internal surface of sleeve pipe, the horn mouth 7 of sealing cup 4 is directed downwards, liquid stream can not flow from the lateral of sealing cup 4, liquid stream can only be entered through interior pipe 5 inside from second side direction feeding device upwards to flow out from the linked hole 2 of UNICOM's joint 1 again, enter first side direction feeding device, thereby satisfy the requirement that series connection has the tubing string control runner of two kinds of side direction oil-feed instruments down.
Claims (3)
