Description
Technical field:
The present invention relates to a kind of inverse circular sand washing adapter connector in rotary type of twin pipe that a kind of oil exploitation workover treatment is used.
Background technology:
In the workover treatment of domestic petroleum exploitation at present, the well head joint that sand washing is used is generally the high pressure movable elbow, and this elbow is a single tube, can only realize that the liquid list enters or single current goes out, and can not realize turnover simultaneously, and it can not satisfy the needs of two-stage tube sand washing process.Therefore, need a kind of a kind of inverse circular sand washing adapter connector in rotary type of twin pipe of using at low absorption well sand flushing of development, this joint is a kind of inner cycle channel that adopts two-tube foundation, makes the sand cleaning fluid sleeve pipe of not flowing through, and has so just stopped the sand cleaning fluid oil layer pollution oil reservoir ground that bleeds.The present invention has novelty and creativeness through patent retrieval referral centre of State Intellectual Property Office retrieval on June 12nd, 2007 (G071096).
Summary of the invention:
The purpose of this invention is to provide a kind of inverse circular sand washing adapter connector in rotary type of twin pipe, it is single tube that this joint has solved the high pressure movable elbow sand washing that exists in the prior art, can only the fluid single tube enters or single tube flows out the problem that passes in and out of can not realizing simultaneously.Inverse circular sand washing adapter connector in rotary type of twin pipe of the present invention is to adopt to import and export to be the rotatable two-stage tube joint of one, and cooperate whole tubing string of twin-stage and anti-circulation parallel pipe water jet pump to carry out the low-pressure absorption well sand flushing operation, form import and export and be the power circulation system of one.
The technical solution adopted for the present invention to solve the technical problems is: a kind of inverse circular sand washing adapter connector in rotary type of twin pipe, be made up of sand washing tube connector and union elbow, hold-down ring, gasket ring, thrust bearing, O RunddichtringO, special sealing ring, threeway conical shell, support housing: threeway conical shell one side is provided with oblique inlet opening, side is a closed shell in addition, in threeway conical shell upper and lower part, be respectively equipped with the preformed groove of thrust bearing, O RunddichtringO and special sealing ring; Thrust bearing, O RunddichtringO and special sealing ring are respectively charged in its preformed groove, on the thrust bearing preformed groove on threeway conical shell top, gasket ring and hold-down ring are housed, gasket ring and hold-down ring and support housing screwed connection, sand washing tube connector and union elbow and support housing screwed connection.Inverse circular sand washing adapter connector in rotary type of twin pipe when work: with this sand washing joint in union elbow place and hose screwed connection, connect two-tube under sand washing tube connector and the support housing: the twin-stage central tube directly is inserted in the sand washing tube connector, outer tube is by the housing screwed connection, the two-tube sand face place of visiting, pump truck is suppressed by hose liquid is entered from threeway conical shell joint, special sealing ring and O RunddichtringO have guaranteed the sealing in space up and down up and down, owing to block above the ring-like space, liquid can only dash downwards, go out sand setting, sand is dug, upwards returned out in the twin-stage central tube sand is returned ground, realize the purpose of sand washing.
The invention has the beneficial effects as follows that this sand washing joint can connect the twin-stage oil pipe, can realize rotatory sealing, carries out inverse circular sand washing adapter or well-flushing; This sand washing joint effectively is connected the ground dynamical system with well head, forms to import and export to be the power circulation system of one, and importing and exporting separately, forms two autonomous channels, is convenient to operation; It also has spinfunction, can guarantee to unload screw thread on the normal oil pipe.
Description of drawings:
Accompanying drawing is an overall structure schematic diagram of the present invention.
Among the figure 1, sand washing tube connector and union elbow, 2, hold-down ring, 3, gasket ring, 4, thrust bearing, 5, the O RunddichtringO, 6, special sealing ring, 7, the threeway conical shell, 8, support housing.
The specific embodiment:
In the accompanying drawings, a kind of inverse circular sand washing adapter connector in rotary type of twin pipe, form by sand washing tube connector and union elbow 1, hold-down ring 2, gasket ring 3, thrust bearing 4, O RunddichtringO 5, special sealing ring 6, threeway conical shell 7, support housing 8, threeway conical shell 7 one sides are provided with oblique inlet opening, side is a closed shell in addition, in threeway conical shell upper and lower part, be respectively equipped with the preformed groove of thrust bearing 4, O RunddichtringO 5 and special sealing ring 6; Thrust bearing 4, O RunddichtringO 5 and special sealing ring 6 are respectively charged in the preformed groove, gasket ring 3 and hold-down ring 2 are housed on thrust bearing 4 preformed grooves on threeway conical shell 7 tops, gasket ring 3 and hold-down ring 2 and support housing 8 screwed connections, sand washing tube connector and union elbow 1 and support housing 8 screwed connections.
