Description

The field of technology.

The technical solution relates to the oil and gas industry, namely, devices for hydraulic testing and pressure testing of blowout equipment (preventers, a complex of sealing equipment, transition coils and other equipment with flange connections) in order to check for strength, tightness and performance.

The prior art.

Blowout control equipment refers to equipment of increased danger. Blowout control equipment is designed to seal wellheads for the purpose of safe work, preventing emissions and open fountains. Blowout control equipment must comply with safety requirements. In accordance with the safety requirements in the gas and oil industry, blowout equipment mounted at the wellhead during their drilling and operation and operating under the pressure of the downhole medium (various types of preventers, transitional coils, crosspieces, fountain fittings, pipe heads, etc.) before installation must be subjected to mandatory hydraulic tests (pressure testing) for strength and tightness by the action of excessive pressure of the working fluid, as well as performance and ge shutter tightness. In order to ensure operational efficiency and reliability, blowout control equipment is subjected to hydraulic tests and crimping, both during production, in the factory, before installation at the mouth, and periodically during operation, to confirm reliability and performance in the field. Data on the progress of hydraulic tests and crimping are necessary to assess the technical condition of the equipment, its reliability, safety, performance. For testing, there are test stations or stands for blowout control equipment designed to carry out work to assess the technical condition of equipment, assess buildings for strength, shutters of working bodies for tightness. Each product (preventer, coil, etc.) installed at the wellhead is subjected to tests, and without testing the products cannot be allowed to operate. Therefore, the registration, recording, preservation of parameters related to the testing of blowout equipment, such as pressure and temperature of the working fluid during the tests, are a prerequisite for the proper control of the technical condition of the equipment, its reliability, safety, performance. In the event of premature equipment failure, emergencies, the stored data on the progress of the tests allow you to analyze and identify the relationship between the behavior of the equipment during testing and during operation. This allows you to improve the equipment and increase its reliability and safety, to monitor the conduct of mandatory tests.

A well-known stand for testing oil and gas and blowout equipment for tightness and strength (source [1], patent RU 61778). The stand [1] includes a system for supplying fluid to the test object (preventer), which includes a pumping station and a high pressure hose (pipelines) for supplying fluid from the pumping station to the lower flange of blowout control equipment. The pump station contains a tank for the working fluid and a hand pump with a suction hose lowered into the tank. The tank is equipped with a lid and has a carry handle. The tank cap has a cut-out for the passage of the suction hose. The suction hose is equipped with a filter. A pressure gauge, a pressure fitting, to which a high pressure hose (pressure pipe), and a drain fitting are connected, are installed on the high-pressure chamber of the pump. A tap is fixed to the drain fitting through the gasket, to which a drain hose connected to the tank is connected.

The fluid supply system to the test object (test pump station) [1] does not allow electronic recording and storage of parameters (pressure and / or temperature) of the working fluid. The described analogue [1] is not adapted for interaction with an electronic computer (computer) and does not allow recording and storing in electronic form data on the crimping process with the ability to generate a diagram of the working fluid pressure-time with reference to a specific number and type of tested blowout preventer equipment (preventer , coils, etc.). In addition, the analogue [1] does not allow testing the shutoff bodies of blowout control equipment, hydraulic drives of preventer dies or slide plates. The system with a hand pump has low productivity and high labor costs for operation.

The known hydraulic system of the test bench for the strength of pipe fittings (source [2], patent RU 2228466). The hydraulic system contains an electric motor, a pump, a pressure and drain line, an adjustable safety valve between the pressure and drain lines (hydraulic lines), check valves, hydraulic valves, pressure recorders, a tank and a filter, an adjustable safety valve between the second pressure and drain lines and a valve between the pressure lines .

Station [2] does not allow electronic recording and storage of parameters (pressure, temperature) of the working fluid, does not allow recording and storing in a computer in electronic (digital) form the data on the crimping process with the ability to form a test fluid working pressure-time diagram with reference to specific number and type of blowout preventer (preventer, coil, etc.). In addition, the station [2] does not allow testing of hydraulic drives in order to fully verify the operability of a hydraulic preventer.

A known bench for crimping gas and oilfield equipment (source [3], patent RU 2190081). The stand for pressure testing of gas-oilfield equipment consists of a high-pressure pump unit, a line for pumping the working fluid. It has a control system, regulation and control of the pressure of the injected working fluid. The pressure of the working fluid in the pressure lines of the hydraulic system is controlled by five pressure gauges.

The stand [3] does not allow electronic recording and storage of parameters (pressure, temperature) of the working fluid, does not allow registering and storing in a computer in electronic form data on the crimping process with the ability to create a load-time diagram with reference to a specific number and type of blowout equipment . In addition, the stand does not allow the performance test of hydraulic drives of hydraulic preventers, including dual preventers.

Thus, from the prior art it follows that existing technical solutions do not allow electronic registration and storage of parameters (pressure, temperature) of the working fluid during the tests for strength, tightness and operability of blowout control equipment. Well-known test stations do not allow to save data on the test progress (time, pressure and temperature of the working fluid for pressure testing of the housing and testing of hydraulic actuators, valves) on computers in electronic form, which complicates their storage, processing, analysis and the possibility of extraction to confirm the success of testing a particular product .

Using a computer to process data on the value of the parameters of the working fluid during the tests allows more efficient full-fledged technical assessment of the performance, reliability and safety of blowout control equipment, including equipment equipped with hydraulic actuators of shut-off bodies (valves).

The claimed technical solution is aimed at improving the design of the testing stations to ensure registration, recording, storage, analysis of data on the progress of hydraulic tests of blowout control equipment, testing of hydraulic actuators, valves and crimping the case.

EFFECT: possibility of registering, storing and transmitting in electronic form data on the parameters of the working fluid obtained during equipment testing, on the strength of the housing, on the tightness of the shutter and on the operability of the hydraulic actuators of the shutoff bodies of blowout control equipment. Data is recorded, stored and transmitted with reference to a specific number and type of equipment using a computer (personal computer).

The technical result is achieved by the fact that the test station for blowout control equipment contains a hydraulic tank intended for filling with working fluid, hydraulic lines including pressure and return pipelines, a pump designed to supply working fluid under pressure from the tank to the pressure piping, connections for connecting hydraulic lines to blowout control equipment, the control panel on which the controls are mounted, a pressure gauge connected to the pressure pipe. It differs in that it contains hydraulic lines designed for hydraulic testing of hydraulic actuators and hydraulic lines for crimping blowout control equipment of different (different) working pressure, it contains an element that measures and converts the values of the measured parameters of the working fluid into an electrical output signal, intended for transmission to electronic a computer, which is an electronic autonomous digital pressure gauge-thermometer connected in hydraulic These lines are made in a compact metal container, on the top cover of which a control panel is located, on the control panel are mounted controls for the flow of working fluids and elements for controlling the parameters of working fluids for controlling hydraulic drives and crimping.

The hydraulic line for testing the performance of preventer hydraulic actuators is made with a working pressure of up to 25 MPa, the hydraulic line for pressure testing for testing the preventer housing for strength and the valves for tightness is made with a working pressure of working fluid of 70 MPa or 200 MPa.

The first hydraulic system is designed for hydraulic testing of double preventer hydraulic drives with a working pressure of hydraulic oil (first working fluid) up to 25 MPa. The second hydraulic system - the ultra-high pressure line is designed for crimping the preventer body with process water (second working fluid) with a pressure of up to 200 MPa. The second hydraulic system contains an element that measures and converts the values of the measured parameters of the working fluid into an electrical output signal, made in the form of an electronic autonomous digital pressure gauge-thermometer 32 which converts pressure and temperature into a proportional output voltage signal of electric current.

The ultra-high pressure hydraulic circuit for crimping (block B) is made with an adjustable range of working fluid pressure from 0 to 200 MPa. The hydraulic circuit for testing preventer hydraulic actuators (block B) contains a 4-line hydraulic system for simultaneous testing of 4 hydraulic actuators in order to fully check the operability of a dual preventer. The hydraulic circuit for testing preventer hydraulic drives (block B) has an adjustable working fluid working pressure range of up to 25 MPa. The hydraulic circuit for testing preventer hydraulic drives (block B) contains four high-pressure hoses 5 meters long for connecting to hydraulic drives connected to outputs 12. The station operates from a compressed air source K (Fig. 1) with a pressure of 0.4 to 1.2 MPa The source of compressed air can be a compressor with a working air supply pressure of 0.6 -1.2 MPa, or compressed air can be supplied from the factory line.

The station consists of two independent hydraulic systems: a hydraulic circuit for testing preventer hydraulic drives (block B of FIG. 1), which receives the energy of the first working fluid from a hydropneumatic pump 9 (FIG. 1); hydraulic circuit ultra-high pressure for crimping (block In figure 1), receiving the energy of the second working fluid from the hydropneumatic pump 28 high pressure (figure 1).

Hydropneumatic pumps 9 and 28 and hydraulic tanks 15 and 27 are located in a compact metal container (not shown), on the top cover of which a control panel (not shown) is located. The control panel contains controls for the flow of working fluids and control elements for the parameters of working fluids for controlling the hydraulic actuators of the preventer and pressure testing, including the handles 19 of the control valves 14, the handles of the shutoff valves (shut-off valve 11, ball valve 5, shut-off valve 21, shut-off valve 24), handle pressure regulator, pressure gauges 4,13,23,32.

Job Description for Example 1.

Preparation for work. Tank 15 is filled with the first working fluid - VMGZ oil. Tank 27 is filled with a second working fluid - water. The ultra-high pressure hydraulic circuit for crimping allows you to work with various working fluids: water, aqueous solutions, oils. The connector 33 of the pressure gauge-thermometer 32 is connected to a computer 34.

Before starting up, the station is connected to a source of compressed air K, for example an air compressor or to a stationary factory line of compressed air, the ball valve 1 is opened. High pressure hoses (RVD) are connected via a quick disconnect to the outputs 12 and to the preventer hydraulic drives according to the marking on the RVD: opening deaf dies, closing deaf dies; opening pipe dies, closing pipe dies. Connect ultra-high pressure hoses (RSVD) of 220 MPa for pressure testing, to output 22 and to the flange of the test bench.

Control and management bodies for controlling the flow of working fluids and control elements for controlling the parameters of working fluids for controlling hydraulic actuators for preventer and pressure testing, including handles 19 of directional control valves, handles of stop valves (shut-off valve 11, shut-off valve 21, shut-off valve 24), pressure regulator handle, pressure gauges 4 , 13,23,32 posted on the control panel.

The operating procedure of the station for high pressure crimping with data recording in electronic form.

Install and fix the preventer on the flange of the test bench. Fill the preventer with water and plug the upper flange of the preventer with a test plug with a sealing flange gasket. Connect the RSVD at 220MPa to output 22 and to the flange of the test bench. Fill the tank 27 with a second working fluid (water, a mixture of water and oil). Open the ball valve 29 for supplying a second working fluid from the tank 27 through the sanitary filter 30 to the hydropneumatic pump 28. Open the ball valve 1 for supplying compressed air to the air preparation unit (block A) with filter 2. Close the ball valve 5, open the shut-off valve 24 high pressure and open the ball valve 6 for supplying compressed air to the hydropneumatic pump 28 through the pneumatic pipe 31. After the supply of compressed air starts, the hydropneumatic pump 28 starts automatically. Close the shut-off valve 21.

To set the required pressure of the second working fluid, the pressure of the compressed air supply is adjusted by the pressure regulator 3 by the handle, the air pressure is controlled by the pressure gauge 4, the high pressure of the working fluid in the pressure test pipe 25 is controlled by the pressure gauge 23 and pressure gauge-thermometer 32 measuring and converting values measured parameters of the working fluid in the output electrical signal.

 The signal from the pressure gauge-thermometer 32 through the connector 33 is transmitted to a personal computer 34. An electronic stand-alone digital pressure gauge-thermometer 32 is connected to the pressure test line 25, which converts the pressure and temperature of the working fluid into a proportional output voltage signal of electric current. The manometer-thermometer 32 consists of a housing, a pressure and temperature sensor, and an electric board. The manometer-thermometer 32 works according to the internal program under the control of the built-in controller, which processes the information from the sensors, saves the parameters and measurement results in a long-term non-volatile memory. The measuring principle of the manometer-thermometer 32 is based on the conversion of the electrical resistances of the pressure transducer (pressure transducer) and the temperature transducer (temperature transducer-thermoresistance) into an electrical signal. Connect the manometer-thermometer 32, through the connector 33, to a computer 34 containing compatible software, and carry out electronic recording and preservation of the parameters (pressure and temperature) of the working fluid during crimping. The temperature pressure parameters are displayed on the computer screen in the form of diagrams.

To supply the test fluid with a pressure of 200 MPa, the compressed air pressure is set to 0.72 MPa (conversion coefficient in the hydropneumatic pump 28 of an ultrahigh pressure 280: 1).

The pressure regulator 3 smoothly raises the pressure in increments of 5 ... 10 MPa in accordance with the instructions disclosed in the method of crimping the preventer.

Upon reaching the required value of the test pressure, close the shutoff valve 24. After pressure testing the preventer to release pressure, open the shutoff valve 21. Close the ball valve 6 to turn off the hydropneumatic pump 28. Open the shutoff valve 24 high pressure to relieve the residual pressure of the second working fluid in the hydropneumatic pump 28.

Thus, they provide pressure testing of the housing by independently supplying a second working fluid to check the strength and tightness with the ability to record and save the working fluid parameters in electronic form.

The operating procedure of the station for testing hydraulic drives.

Fill the hydraulic tank 15 with hydraulic oil (VMGZ). Open ball valve 7 for supplying the first working fluid from tank 15 through oil filter 8 to the hydropneumatic pump 9. Open ball valve 1 for supplying compressed air to the air preparation unit (block A) with filter 2. Open ball valve 5 for supplying compressed air from air preparation unit (block A) to the hydropneumatic pump 9 through the pneumatic line 16, while the ball valve 6 is closed. After the supply of compressed air starts, the hydropneumatic pump 9 is automatically started. The shut-off valve is closed 11. To set the required pressure of the first working fluid, the compressed air supply pressure is adjusted by the pressure regulator 3 by the handle, the air pressure is controlled by a manometer 4, the pressure of the first working fluid in the pressure head is controlled the test pipeline 17 is produced by a pressure gauge 13. To supply the working fluid with a pressure of 21MPa, the value of the compressed air pressure is set to 0.84 MP a (conversion factor in a hydropneumatic pump 25: 1). After setting a predetermined working pressure by gauge 13, the station is considered ready for testing hydraulic drives.

To open the blind plates of the preventer, the lower handle 19 of the control valve 14 is moved to the “blind open” position, after which visual inspection of the opening of the blind plates on the preventer is carried out and the working pressure is set on the pressure gauge 13.

To close the blind dice of the preventer, the lower handle 19 of the control valve pos. 14 are transferred to the “blind closed” position, after which visual closure of the blind dies on the preventer is carried out and the working pressure is set on the pressure gauge 13.

Similarly, to open the tube dies of the preventer, the upper handle 19 of the control valve 14 is moved to the “pipe open” position, after which visual inspection of the opening of the tube dies on the preventer is performed and the working pressure is set on the pressure gauge 13.

To close the tube dies of the preventer, the upper handle 19 of the control valve 14 must be moved to the "pipe closes" position, then the visual control of the closing of the tube dies on the preventer is carried out and the working pressure is set on the pressure gauge 13.

Protection against exceeding the working pressure in the hydraulic control system (and, accordingly, in the preventer hydraulic actuators) is carried out by the safety valve 10, which is adjustable to a preset value. When the preventer hydraulic actuators are operating, the first working fluid is drained through the drain pipe 18 into the hydraulic tank 15.

After testing the hydraulic actuators for pressure relief, open the shutoff valve 11. Close the ball valve 5 to turn off the hydropneumatic pump 9. To completely release the pressure in the preventer hydraulic actuators, it is necessary (with the shutoff valve 11 open) to move the control valve 19 of the control valve 14 to all operating positions in turn.

This provides a test of the operability and reliability of blowout control hydraulic drives. It is possible to control the supply of the first working fluid with the given parameters to the preventer hydraulic drives.

The station allows for pressure testing of the case and operability testing of blowout control hydraulic drives by independently supplying two different working fluids to check the strength and tightness of the case and to check the working capacity and tightness of the hydraulic drives and to record and save the parameters of the working fluid of the crimping circuit in electronic form.
