Abstract

A device for installing downhole equipment, comprising a housing, a spring, a sealing assembly, characterized in that it is equipped with a spring-loaded movable cylinder that is mounted on the grip-stop rod, and a movable protective and sealing ring located between the spring-loaded movable cylinder and the grip-stop rod.

Description

DEVICE FOR INSTALLING UNDISTRIBUTION EQUIPMENT. E 21 V 43/00 E 21 V 3V06

for installation of downhole equipment, it is used for oil and gas © Combat industry and is intended for fixing downhole equipment in a well.

A device for installing downhole equipment in a well is known, comprising a housing, a fishing neck, a spring-loaded plunger, a latch and a sealing assembly, fixing elements and a sleeve that is mounted on the fishing neck by means of shear elements, while the locking elements are mounted to interact with the fishing neck and sleeve / see Auto.SS.CCC i 968§46 B Bulletin No. 39, 1982 /.

The disadvantage of this device is the difficulty in manufacturing the structure. In addition, the small number of shear elements makes the structure one-time use. After lowering the device into the squeezer and putting it into working position, such a structure is unsuitable for second use. © shear elements and insert a new one, and then remove the construction of the device; П © Such works increase the period of well repair.

The closest in technical essence is the design of a gripping device containing a housing, a gripping rod and a valve system / cm, Ibragimov G, 3,, Khiaamutdinov N, I # Snrav @ chn1v a guide for the use of chemicals in oil production. M ,, NedraM983, c . /.

valves, where mechanical impurities, products of fracture of the skeleton of the productive formation, coming together with the production of the well, get, As a result, lifting of the downhole equipment and washing of the nodes, and often their replacement, are required. The frequency of repairs of intraqualine equipment is increasing, which means the Mescpe installation period of the well is decreasing.

The purpose of the proposed utility model is to increase the reliability of the operation of the unit, simplify its design, and prevent mechanical impurities from entering the rubbing surfaces of the downhole equipment units

This goal is achieved in that the device is equipped with a spring-loaded movable cylinder, which is mounted on a gripping rod, and a movable protective-sealing ring located between the spring-loaded movable cylinder and the gripping-resistant rod.

In Fig. 1, a device for installing downhole equipment in an inoperative position, and in Fig. 2 in a working position.

The device consists of a housing 1, a gripping thrust rod 2, the lower part of which moves a spring-loaded figured cylinder 9 with a protective-sealing ring 4, a collet gripper 5, fastening | the upper rod b, and is nested inside the pump-compressor pipes 7,

The device operates as follows,

The catch-stop rod 2 is attached to the housing I and, together with the spring-loaded figured cylinder 3, is lowered into the squeegee together with the pump plunger on the pump-compressor pipes 7. The housing of the catch-stop rod 2 is the niche rod I, The extended part of the spring-loaded figure cylinder 3, where protective sealing

cylinder, while squeezing the protective-sealing ring 4 in the lowest position. The protrusions of the collet gripper 5, having taken a lower position in the narrowed part of the gripping-thrust rod © of the rod 2, will assume a working position, the fixation of which is provided by the upper part of the spring-loaded figured cylinder 3,

The protective-sealing ring 4 protects the clutch grip of the collet gripper 5 in the narrowed part of the gripping-thrust rod 2. In addition, the mechanical sealing element 4 QT prevents the space above the plunger in the upper part of the rod-type deep-well pump.

The proposed design of the device for installation of downhole equipment is characterized by simplicity, aimed at increasing the overhaul period of oil wells equipped with rod deep grooves. This means an increase in the period of operation of the well, hydrocarbon production, and a reduction in overhaul costs. In addition, when working with a deep installation, alternating dynamic loads occur that adversely affect the threaded connections of the rods. This design has the ability to work equally equally under tension and creep.
