RU114719U1 - INSTALLATION FOR SIMULTANEOUSLY SEPARATE OPERATION OF WELLS - Google Patents

Abstract

Installation for simultaneous operation of well formations, including a long tubing string, a long string plug-in sucker-rod pump, a packer, liner and filter, a short tubing string installed at a depth above the upper productive formation, a parallel anchor installed on both tubing strings and above the upper productive formation, a short-string deep-well pump and a filter, characterized in that a self-contained deep-well device is fixed to the bottom of the long-string plug-in sucker rod pump on the rods, and the length of the rods is made to ensure the location of the deep self-contained device in the long string filter zone

Description

The utility model relates to the oil industry and may find application in simultaneous and separate operation of formations in a well.

A known installation for simultaneous and separate operation of two layers, including the main and additional drives, a packer installed between the upper and lower productive layers, the main communicating with the under-packer space of the well, and the additional communicating with the over-packer space of the well, lift pipes with rod pumps fixed at the wellhead with double-barrel fittings containing a flange with wellhead seals and two channels, equipped with holes for fastening to the wellhead, pipe holder The main elevator pipes, equipped with a thread, and the pipe holder of additional elevator pipes with upper and lower threads, made in the form of a hollow threaded sleeve, which is made with the possibility of tight fixation directly in the second channel of the flange, characterized in that the installation is equipped with a parallel armature mounted on both elevator pipes and made with the possibility of fixing them relative to each other, while the tube holder of the main elevator pipes of double-barreled reinforcement is made in the form of a thread of the first channel Lanza directly below the flange (Russian utility model patent №72720, publ. April 27, 2008).

Closest to the proposed utility model is a unit for simultaneously separate operation of two layers of the well, including a rocking machine, a column of lift pipes, a sucker rod pump, a packer and a liner, as well as an additional rocking machine and an additional short column of lift pipes installed to a depth above the upper productive formation, and a parallel anchor installed on both columns of elevator pipes and above the upper productive formation, while the short column of elevator pipes is equipped with an additional piece Ngovi pump. The sucker-rod and additional sucker-rod pumps are plug-in, with a mesh filter installed on each of them, equipped with a slider inside, with axial movement inside the filter due to differential pressure, which allows you to clean the filter mesh during operation (RF Patent Utility Model No. 65124 , publ. 07/27/2007 - prototype).

The disadvantages of the known installations is the inability to obtain information about the properties of the lower subpacker space.

The proposed utility model solves the problem of providing the ability to obtain information about the properties of the lower subpacker space.

The problem is solved in that in the installation for simultaneous and separate operation of the well strata, including a long column of elevator pipes, a plug-in sucker rod pump of a long column, a packer, a liner and a filter, a short column of elevator pipes installed to a depth above the upper reservoir, a parallel anchor installed on both columns of elevator pipes and above the upper reservoir, a short column deep pump and a filter, according to a utility model, to the bottom of a long rod plug-in sucker rod pump the deep autonomous device is fixed, and the length of the rods is made providing the location of the deep autonomous device in the filter zone of the long column.

Figure 1 presents the inventive installation for simultaneous-separate operation of the layers.

The installation includes a long column of elevator pipes 1, a plug-in sucker rod pump 2 of a long column 1, a packer 3 installed above the lower reservoir 4, a shank 5 and a filter 6, a short column of elevator pipes 7 installed to a depth above the upper reservoir 8, parallel anchor 9 installed on both columns of the elevator pipes 1 and 7, the sucker rod pump 10 of the short column 7 and the filter 11. To the bottom of the insertion pump 2 of the long column 1 on the rods 12 is mounted a deep-seated self-contained device 13, and the length of the rods 12 is made the deep autonomous device 13 is located in the filter zone 6 of the long column 1. The installation is located in the well 14. The pumps 2 and 10 are driven by rod columns 15 and 16. The depth device 13 is attached to the rods 12 and the rod 12 is attached to the bottom of the insert pump 2 through sub 17 and 18 respectively.

Installation works as follows.

Through the columns of the rods 15 and 16, the drive is transferred to the pumps 2 and 10, which supply the products of the productive formations 4 and 8 through the filters 6 and 11, the columns 1 and 7 to the wellhead 14. If necessary, take the readings of the downhole tool 13 and stop the production selection through a long column 1, using a string of rods 15 lift the insertion pump 2 from the well, and with it the rods 12 and the depth tool 13. At the mouth, read the readings of the device 13 and again lower the entire arrangement into the well 14. Using the proposed installation allows you to lift the depth device 13 with minimal interruptions in oil production, without lifting a short 7 and a long 1 column from a well 14.

The application of the proposed installation will make it possible to obtain information about the properties of the lower sub-packer space without unpacking and lifting from the well a short and long column of elevator pipes.
