Description

The invention relates to oil and gas production in the direction of well repair and can be used to clean the hydraulic part of a water pump used as part of the special equipment of a mobile steam generator for carrying out technological operations to remove saturated steam of hydrate-paraffin deposits in tubing during oil and gas production.

During the above technological operations, in the hydraulic part of the water pump, which is part of the equipment of the mobile steam generator (PPU), some water may remain, which when operating the PPU in the open air during inter-shift storage at low temperatures (for example, in far north) can lead to thawing of the valve body.

At the same time, from CN 106286270 A, January 4, 2017, a device for cleaning the hydraulic part of the water pump of a mobile unit containing a water tank communicated through a shut-off element with a water pump hydraulic unit and installed on the vehicle chassis with a standard internal combustion engine compressor in series is known and a receiver, the latter being connected by a high pressure sleeve to a water supply line to said valve body having a shut-off valve for adjusting the compressed air supply.

A disadvantage of the known device is the complexity of its implementation, due to the need to disassemble the pipeline of the pumping unit for connection to an exhaust system.

The problem to which the claimed invention is directed, is to provide the ability to clean the hydraulic part of the water pump of a steam generator without disconnecting the installation from the consumer and further disassembling it.

The technical result is to simplify the process of cleaning the hydraulic part of the water pump used in the special equipment of a mobile steam generator from water residues.

The specified technical result is achieved through the use of the proposed device for cleaning the hydraulic part of the water pump of a mobile unit containing a water tank communicated through a shut-off element with a water pump hydraulic unit and mounted on a car chassis with a standard internal combustion engine compressor and receiver connected in series, the latter being connected by a sleeve high pressure with a water supply line to the said valve body having a shut-off valve for regulating the supply of compressed air, into which rum according to the invention, when using the device in a steam generator installation including a steam boiler, the latter is connected via a water pump with a water tank, the water pump has a valve in its lower part and at the outlet to the water supply line to the steam boiler, with taps for draining the water, and shut-off element and shut-off valve combined

Moreover, in special cases of the device, it is advisable to use PPU 1600/100 as a steam generator, and a 1.1 PT pump as a water pump.

The claimed invention is illustrated by a drawing, which shows a diagram of the proposed device that implements a method for removing compressed water from the hydraulic part of a water pump using compressed air, consisting of the following structural elements:

1 - water tank;

2 - water supply line from the water tank to the hydraulic unit of the water pump;

3 - valve body of the water pump;

4, 5 - taps for draining water;

6 - water supply line from the valve body of the water pump to the steam boiler;

7 - steam boiler;

8 - a standard internal combustion engine compressor;

9 - line of the pneumatic system of the vehicle chassis;

10 - receiver;

11 - receiver fitting;

12 - a sleeve of a high pressure;

13 - locking body (ball shut-off valve).

The chassis of the car is not conventionally shown.

To remove residual water from the hydraulic part of the water pump with compressed air to the nozzle 11 of the receiver 10, a high pressure sleeve 12 is mounted using a thread-nut connection to supply air to the pump. With the use of welding, a shut-off element 13 is welded into the water supply line 6 in the form of a ball shut-off valve, to which a high-pressure sleeve 12 is attached using a threaded connection. In the lower part of the valve body 3 mounted faucet 4 to drain the water. The second crane 5 for draining the water crashes into the water supply line 6 to the steam boiler 7 immediately after the hydroblock 3. It is preferable to use factory taps of the Ural automobile cooling system as drain taps 4, 5. These taps are sufficient to completely remove the remaining water.

Cleaning the hydraulic part of the water pump of a mobile steam generator is as follows.

After completion of the technological process for the removal of saturated hydrate-paraffin deposits in tubing during oil and gas production, the PPU driver opens taps 4, 5 to drain the water. Then it opens the locking element 13 in the form of a ball shut-off valve for supplying compressed air to the line 2. There is a purge of compressed air from the receiver 8 of the vehicle brake system to the hydraulic part of the water pump. The remaining water is completely removed from the valve body 3 through taps 4 and 5 with hoses outside the kung.

Thus, the compressed air from the receiver 7 of the circuit of the brake system of the car chassis, which is not used during the operation of the PPU installation, enters through the high-pressure hose 12 (hose) to the hydraulic unit 3 of the pump in order to remove residual water.

The use of the invention provides for the removal of compressed water residues from the hydraulic part of the water pump, which is part of the equipment of a mobile steam generator, used in carrying out technological operations to remove saturated hydrate-paraffin deposits in tubing during oil and gas production. This allows you to increase the overall reliability of the water pump, and also eliminates the likelihood of defrosting the valve body and improves the working conditions of the PPU driver, increasing the culture of production.
