RU98780U1 - HOLE SEALER WITH PIPE HOLDER - Google Patents

Abstract

 1. Wellhead sealant with a pipe holder, comprising a hollow cylindrical body with a lower flange, in the axial channel of which a support flange is made, which is a support for installing an elastic sealing element, and at least one ring, which is a sliding bearing, a nut screwed into the corresponding thread made in the axial channel of the housing, with the possibility of pressing the nut of the sealing element to compensate for its wear, characterized in that a hollow pipe holder with second inside thread to the tubing, wherein the fixed tube holder cap screwed onto the housing at the top sealer. ! 2. The sealant according to claim 1, characterized in that on the outer surface in the upper part of the pipe holder of the sealant a thread is made for installing a flange or connecting to other wellhead equipment.

Description

The utility model can be applied in the oil and gas industry, and relate to devices designed to seal the wellhead during their development and repair, including during hydraulic fracturing, to ensure safe operations, prevent emissions, and protect the environment Wednesday.

A wellhead sealer device is known (RF Patent for Utility Model No. 86229 MPK ЕВВ 33/06 published on August 27, 2009) for sealing a wellhead during geophysical work on a well, comprising a cylindrical body in which annular sealing elements, a pressure ring, which is a pressure ring, are a nut, spacer sleeves having an inner bore forming a support flange serving as a support for the elastic cuff.

A disadvantage of the known device is the design complexity, the lack of a function in the device for fixing and holding the tubing, which requires the use of an additional device with the functions of the tubing holder.

A wellhead sealer device is known (RF Patent for Utility Model No. 89167 MPK ЕВВ 33/03 publ. November 27, 2009), comprising a hollow cylindrical body with upper and lower flanges, in the axial channel of which a sealing element is installed, and a compression nut for fixing the sealing element.

A disadvantage of the known device is the lack of a function for fixing and holding the tubing (tubing), which in the case of using the known device requires the use of an additional device with the functions of the tubing tubing.

The objective of the invention is to expand the functionality of the wellhead sealant.

The technical result that can be achieved using the inventive utility model is to expand the functionality of the device.

To achieve the technical result, a wellhead sealant with a pipe holder is proposed, comprising a hollow cylindrical body with a lower flange, in the axial channel of which a support shoulder is made, which is a support for the sealing elastic element, and at least one ring, which is a sliding bearing, a nut screwed into the corresponding thread made in the axial channel of the housing, with the possibility of pressing the nut of the sealing element to compensate for its wear. In the upper part, a hollow pipe holder with a thread made inside for tubing is installed. The pipe holder is fixed by a cap screwed onto the housing at the top of the sealant.

The proposed solution allows the device during work to hold the tubing while sealing the wellhead.

The utility model is illustrated by drawings, where:

Figure 1 shows a longitudinal section of a wellhead sealant with a pipe holder;

Figure 2 shows the wellhead sealant when working with the tubing;

The wellhead sealant consists of a hollow cylindrical body 1 with a through axial channel 2, inside of which a sealing element 3 is mounted, resting on the shoulder 4. Two rings 5, which are a sliding bearing, are installed above the sealing element. The sealing element is pressed with a nut 6 to seal the element in the housing of the sealant. A hollow pipe holder 7 with an internal thread for tubing 8. The pipe holder is fixed to the sealant body by a cap 9, which is screwed onto the threaded part 10 of the housing. A thread 11 is made on the outer surface in the upper part of the sealant to install a flange 12, or to connect with other wellhead equipment.

The device operates as follows:

The sealant is installed with the bottom flange at the wellhead, then the installation is made through the sealing element of the tubing by screwing the pipe holder onto the threaded section of the corresponding pipe, after which the pipe holder is installed in the upper part of the sealant, fixed with a cover. The pipe holder provides a stationary state of the tubing during work, and the sealing element seals the wellhead.

Claims (2)

1. Wellhead sealant with a pipe holder, comprising a hollow cylindrical body with a lower flange, in the axial channel of which a support flange is made, which is a support for installing an elastic sealing element, and at least one ring, which is a sliding bearing, a nut screwed into the corresponding thread made in the axial channel of the housing, with the possibility of pressing the nut of the sealing element to compensate for its wear, characterized in that a hollow pipe holder with second inside thread to the tubing, wherein the fixed tube holder cap screwed onto the housing at the top sealer. 2. The sealant according to claim 1, characterized in that on the outer surface in the upper part of the pipe holder of the sealant a thread is made for installing a flange or connecting to other wellhead equipment.
