Abstract
The utility model discloses a dense plugging type double channel suspension joint for an injection-production integration well, comprising a suspension joint body. The body is vertically provided with a main channel for suspending an oil pipe and a side channel for suspending an electric pump set. The upper end of the main channel is provided with an upper taper port, and the lower end is provided with a lower taper port, and the middle is provided with a variable diameter type inner sealing chamber. The lower end of the side channel is provided with a taper port, and the upper end of the side channel is bended by 90 DEG and is communicated with the variable diameter type inner sealing chamber. The axis of the lower taper port does not overlap with but is in parallel with the axis of the variable diameter type inner sealing chamber. A spacing step is formed at the connecting part between the upper end of the lower taper port and the lower end of the variable diameter type inner sealing chamber. The outer side of the body is also provided with an overcurrent cable trough. The joint has a reasonable size, and is capable of integrating injection and production in a large capacity in a cased well of 9-5/8in. The joint is provided with the sealing chamber and the spacing step, and thereby the locating and sealing of a sealing device can be realized. The operation of the on-site construction is simple and convenient. The joint is an integrated structure, ensuring mechanical strength and high-temperature and high-pressure work environment.
Description
Technical field
The utility model relates to the oil exploitation joint, specifically a kind of close slotting formula binary channels suspension joint for the same well production-injection well.
Background technology
In oil field development, in order to meet the requirement of the complicated technology technology such as test, demixing injection-production, usually to hang with two suspension joints the downhole production tubing strings such as test string, electric pump unit at sea.But current suspension joint comprehensive utilization ratio is not high, can not realizes the oil-extracting and water-injecting of same well or adopt the function of water water filling.
In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the close slotting formula binary channels suspension joint for the same well production-injection well of above-mentioned disappearance.
Summary of the invention
The purpose of this utility model is to provide a kind of close slotting formula binary channels suspension joint for the same well production-injection well, have simple to operate, latus rectum large, can realize that concentric double pipe adopts the characteristics of pouring functions.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, a kind of close slotting formula binary channels suspension joint for the same well production-injection well, comprise the suspension joint body, and described body vertically offers the main channel for hanging oil pipe and is used for hanging the wing passage of electric pump unit.
Upper end, described main channel is upper conical interface, and lower end is the inferior pyramidal interface, and centre is annular seal space in reducing type.
Cone-shaped interface is offered in described wing passage lower end, and upper end 90 degree turnings is communicated to annular seal space in reducing type.
Described inferior pyramidal interface axis does not overlap but is arranged in parallel with annular seal space axis in reducing type.
In described inferior pyramidal interface upper end and reducing type, connection, annular seal space lower end forms limited step.
The described body outside also was provided with cable channel.
Compared to prior art, the utlity model has following beneficial effect:
(1) this suspension joint Sizes can realize in the 9-5/8in cased well that large discharge capacity adopts the notes integrated function;
(2) in this suspension joint, an annular seal space and limited step are arranged, can realize being located and packing of sealing device, on-site construction operations is simple, convenient;
(3) this suspension joint is integrated and can guarantees mechanical strength and high-temperature high-pressure work environment.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of close slotting formula binary channels suspension joint for the same well production-injection well of the utility model;
The upward view that Fig. 2 is Fig. 1;
The structural representation that Fig. 3 is the insertion sealed joint.
In figure: 1, body; 2, upper conical interface; 3, inferior pyramidal interface; 4, wing passage; 5, annular seal space in reducing type; 6, cross cable channel.
The specific embodiment
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, yet accompanying drawing only provides the use of reference with explanation, not is used for the utility model is limited.
Shown in Fig. 1-3, a kind of close slotting formula binary channels suspension joint for the same well production-injection well, comprise suspension joint body 1, and described body 1 vertically offers the main channel for hanging oil pipe and is used for hanging the wing passage 4 of electric pump unit.The upper end, main channel is upper conical interface 2, and lower end is inferior pyramidal interface 3, and centre is annular seal space 5 in reducing type.The body outside also was provided with cable channel 6.
Cone-shaped interface is offered in the wing passage lower end, and upper end 90 degree turnings is communicated to annular seal space in reducing type.Inferior pyramidal interface axis does not overlap but is arranged in parallel with annular seal space axis in reducing type.In inferior pyramidal interface upper end and reducing type, connection, annular seal space lower end forms limited step.
During concrete implementation and operation, first connect lower end, main channel tubing string, then connect wing passage tubing string string (flange connection), cable and test line are by cable channel fixing, connect afterwards upper end, main channel tubing string, be lowered to down the interior tubing string string of band insertion type sealing device (accompanying drawing 3) after design attitude, by limited step, limit the tubing string depth of setting.
Both sides, the utility model lower end can hang the electric pump unit that 2-7/8in oil pipe and external diameter are 116mm simultaneously.The device top connection connects the 4in oil pipe, and an annular seal space is arranged in joint, can realize that external diameter is being located of 70mm sealing plug and packing.
Can realize the oil-extracting and water-injecting of same well or adopt the function of water water filling, improve like this comprehensive utilization ratio of same well.Be applicable to the 9-5/8in cased well, the device top connection connects the 4in oil pipe, and the above flow string of this joint can realize that concentric double pipe adopts pouring functions, and an annular seal space is arranged in joint, can realize being located and packing of sealing device.Compare with two suspension joints of routine, not only can realize basic two hanging functions, can also realize the two-way flow of Produced Liquid and injection liquid, and cable channel can be by electric-pump cable and liquid controling pipe line.
The foregoing is only preferred embodiment of the present utility model, non-in order to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
