Description

A kind of band stretches adjustable tubing hanger device

Technical field

The utility model relates to oil exploration equipment field, in particular to a kind of band stretches adjustable tubing hanger device.

Background technique

Tubing hanger device is an important component in production tree equipment, and common tubing hanger is to sit to hang over oil pipe four It prevents from falling into well on the step of logical internal diameter, the upper flange of oil pipe four-way is pushed down by jackscrew and prevented at the neck of tubing hanger It alters, tubing hanger lower end connected pipes, upper end, which is connected by oil pipe four-way with production tree, realizes christmas.If in the middle chance of exploitation To viscous crude or the regional christmas of cold, at this time just need artificially to arrive toward the high temperature and high pressure steam of 350 DEG C or so of injection in well Soften petroleum in the oil reservoir of the earth's crust, so that viscous crude is thinned out and be conducive to exploitation.So problem is also just come, and downhole temperature is so high, According to expanding with heat and contract with cold, temperature very Gao Shihui keeps oil pipe with altering in tubing hanger that equipment top is bad, and oil pipe is with oil when temperature reduces Pipe hanger decline can destroy the sealing on pipe hanger, and oil gas leakage is caused to lead to the major accidents such as explosion even blowout.Oil/gas well in the past Bottom hole temperature (BHT) is monitored in real time in production, and oil/gas well is closed according to bottom hole temperature (BHT) and stops christmas, then goes to intervene by people It replaces suitable oil pipe and tubing hanger and adjusts height up and down again, the material resources that not only wasted financial resources but also influence to produce, especially make under water Industry is even more difficulty.Obviously frequently replacement oil pipe four-way, oil pipe are also not allow, because bottom pressure is relatively high, band press operation Abnormally dangerous industry is unpractical in actual production.

Utility model content

Stretch adjustable tubing hanger device the purpose of the utility model is to provide a kind of band, no matter environment, bottom hole temperature (BHT) Just, oil pipe and tubing hanger can be freely up and down movable, more will not influence normal production without artificial intervention.

In order to achieve the goal above, the utility model is achieved through the following technical solutions:

A kind of band stretches adjustable tubing hanger device, its main feature is that, comprising:

Tube assembly is increased, the raising tube assembly includes that the first raising manages, increases pipe phase with first by connecting flange Second even increases pipe；

It is set to the boll-weevil hanger increased in tube assembly, the boll-weevil hanger can increase pipe and second liter first It moves up and down in senior executive；

The boll-weevil hanger lower end connects an oil pipe.

Seal assembly is equipped in the connecting flange internal diameter groove, for sealing boll-weevil hanger.

Described first increases pipe upper end and is equipped with the first upper flange, and described first, which increases pipe lower end, is equipped with the first laxative remedy Orchid, first upper flange are connected with connecting flange lower end.

Described second increases pipe lower end and is equipped with the second lower flange, second lower flange and connecting flange upper end phase Even.

Gasket ring, second lower flange and connecting flange are equipped between first upper flange and connecting flange lower end Gasket ring is equipped between upper end.

The tubing hanger device further include:

Voussoir is set in the first lower flange；

Jackscrew, one end are connected with voussoir, and the other end passes through the radial opening of the first lower flange, and is located at the first lower flange Outside.

The utility model compared with prior art, has the advantage that

No matter environment, bottom hole temperature (BHT) height, pressure height, whether Operating Pressure, toward the shaft bottom note nothings such as high temperature and high pressure steam Need closing well to stop production, oil pipe and tubing hanger can freely up and down normal production, not only improve efficiency, but also saved life Produce cost.

Detailed description of the invention

Fig. 1 is that a kind of band of the utility model stretches the structural schematic diagram of adjustable tubing hanger device；

Fig. 2 is the partial enlarged view of Fig. 1；

Fig. 3 be temperature rise when boll-weevil hanger with oil pipe increase pipe in structural schematic diagram；

Fig. 4 be temperature decline when boll-weevil hanger with oil pipe increase pipe in structural schematic diagram.

Specific embodiment

The utility model is done and is further explained by the way that a preferable specific embodiment is described in detail below in conjunction with attached drawing It states.

As shown in Figure 1, 2, a kind of band stretches adjustable tubing hanger device, comprising: increases tube assembly, the raising pipe Component include the first raising pipe 1, by connecting flange 8 with first raising pipe 1 be connected second raising pipe 2；It is set to raising pipe Boll-weevil hanger 3 in component, the boll-weevil hanger 3 can move up and down in the first raising pipe 1 and the second raising pipe 2, In a particular embodiment, boll-weevil hanger 3 is mandrel type boll-weevil hanger；The boll-weevil hanger lower end connects an oil pipe 7, on End is equipped with ACME screw thread, is connected by oil pipe four-way with production tree and realizes christmas.

Seal assembly is equipped in the connecting flange internal diameter groove, it is specifically, above-mentioned for sealing boll-weevil hanger Seal assembly is dustband 9, wear ring 10, T sealing 11, wear ring 12 and P sealing 13.

Described first increases pipe upper end and is equipped with the first upper flange, and described first, which increases pipe lower end, is equipped with the first laxative remedy Orchid, first upper flange are connected with connecting flange lower end.Described second increases pipe lower end and is equipped with the second lower flange, described The second lower flange be connected with connecting flange upper end, by bolt, nut 4 by method on the second lower flange, connecting flange and first Orchid is connected.

Gasket ring 15, second lower flange and connection method are equipped between first upper flange and connecting flange lower end Gasket ring 14 is equipped between blue upper end.
