Description

The utility model relates to the fountain fittings of deep-sea fluid production, in particular to the improvement of the module layout system, fluid management and the improvement of maintenance systems and the simplification of the assembly of fountain fittings, ensuring the unification, modularity and reduction of the laboriousness of manufacturing and production of the works on its assembly and operation.

Fountain fittings are installed on the wellhead to provide services for producing well fluids. Fountain valves provide fluid flow control with the help of valves installed in it, chokes, various sensors and piping systems. Also, fountain valves provide preventive and repair work of the wellhead.

Known fountain fittings (utility model patent No. 188422, class F16K 3/00, publ. 04/11/2019), containing a branched pipe system with a Central barrel housing, which is attached to the wellhead, including a flow line branch with sequentially located valves . This valve has no direct connection with the underwater control module.

In the world practice of building fountain fittings, the modularity of structures has become the main trend, and the functional units, which most often go out of working condition, have been assembled into extractable modules. It should be noted that in the world there are several manufacturers of underwater mining equipment. These are FMC Kongsberg Subsea AS, Aker Solutions, GE Vetco Gray, Cameron. GE Vetco Gray is a leading company in the concept of fountain fixtures.

Traditionally, GE Vetco Gray divides the fountain assembly into three main modules, which include the upper module, the lower module and the throttle bridge module. In one embodiment, the implementation of the upper module of the fountain valve comprises a pipe head of the fountain valve, and the lower module of the fountain valve contains a guidance system and means for connecting the pipelines to the infield infrastructure, and the throttle bridge module contains a throttle and a measuring bridge that connects all three components. Each fountain valve module is functionally improved to unify the technological processes of fluid control, preventive and repair work.

The closest in technical essence to the claimed technical solution is a fountain according to the patent of GE Vetco Gray for the invention RU No. 2505664 C2, publ. 01/27/2014, where all the functional components of the fountain fittings are assembled into structural modules:

- fountain fittings and frame (FA and frame);

- choke module (CMM);

- software control module (PMU), where the PMU ensures the coordinated operation of all components by the FA module.

The technical problem is the creation of a modular design of fountain fittings, which could be used in deep-water production of well fluids with increased uptime.

The technical result is to increase the uptime of the well.

The problem is solved, and the technical result is achieved by the fact that in the modular node of the fountain valves containing the basic module "Fountain valves and frame", "Fitting module" and "Underwater control module", the module "Fountain valves and frame" is equipped with a removable submodule of the base "Underwater control module ”, and in the“ Choke module ”there are two submodules of paired throttling lines, which are equipped with the ability to switch using a remotely controlled telecontrol uninhabited underwater vehicle, while Each submodule has a duplicated system of sand removal sensors. The base of the “Underwater control module” and the removable submodule of the base of the “Underwater control module” can be equipped with an interface flushing device.

In FIG. 1 shows a General view of the FA modular assembly, where:

1 - module containing a FA with strapping and frame (FA with a frame);

2 - choke module (CMM);

3 - underwater control module (PMU).

In FIG. 2 shows a General view of the FA module and the frame, where:

4 - frame;

5 - coupling;

6 - valve block;

7 - PMU casing;

8 - CMM interface;

9 - control panel for TNPA (remote-controlled uninhabited underwater vehicle);

10 - control interface of the slide gate valve of the flow line;

11 - throttle valve for the injection line of chemicals;

12 - panel BRS (quick disconnect hydraulic connectors);

13 - flow line pipeline;

14 - catcher;

30 - washing system interfaces PMU

31 - interface of the washing system.

In FIG. Figures 3 and 4 show the submodule of the base of the PMU with a duplicated system of FA interfaces with a frame and PMU, where:

15 - interface for contact with the FA with the frame;

16 - interface for contact with PMU;

17 - housing submodule base.

In FIG. 5 presents PMU, where:

18 - interface for contact with the FA with the frame;

19 - housing PMU;

20 - TNPA interfaces

In FIG. 6 presents CMM, where:

21 - frame ШМ;

22 - duplicated throttle;

23 - interface coupling;

24 - throttle control interfaces;

25 - gate valve 1 inch;

26 - sand emission sensors;

27 - throttle MEG (mono ethylene glycol liquid for the prevention of waxing processes);

28 - interface switching duplicate systems;

29 - shock absorbers.

The modular assembly of the fountain valves works as follows:

The base submodule PMU 17 is initially installed on the standard interface under the PMU 3 on the FA with frame 1, which performs all the functions of the base of the PMU. The need for submodule 17 is justified by the fact that during operation of FA 1, the contact area is silted and when the PMU 17 is removed for preventive or repair work, there is a possibility of possible failure of some connectors 15, which can be determined when the PMU 17 is installed in its regular place. Then, it will not be necessary to extract the entire FA, but only to remove the submodule of the PMU 17 base, which will save working technological time for FA maintenance and well operation means.

Before installing PMU 17 on the base interface of the PMU, a technological operation of washing the interface connectors is performed using the interface washing system 30, which has a hydraulic actuator, a high pressure pump and a hose with a spray tip. The device washer control system 30 operates in two modes: automatic and emergency using TNPA. In automatic mode, the washing of interfaces occurs by changing the direction and place of the release of water flows under high pressure and temperature within 120 ... 150 ° C, which eliminates the appearance of shadowy not washed portions of the interface contacts behind the protruding interface elements.

Paired throttling lines 22 are provided in the CMM, which operate sequentially after switching the interfaces 24 in the event of a failure of the working line, which are also equipped with sand removal sensor systems 26, which reduces technological downtime for replacing the removed cartridges, as these operations are performed in parallel with other .

Duplication of functional critical components in fountain valves will reduce downtime and increase the period of uninterrupted operation of the well.
