Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings, in which: Figure 1 The schematic diagram illustrates the structure of a conversion device for a pressure sensor according to the present invention; Figure 2 The illustration schematically shows a specific embodiment of a conversion device for a pressure sensor according to the present invention.

[0017] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0018] To make the technical solution and advantages of this utility model clearer, the exemplary embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0019] Currently, during the pressure testing of well control devices in the field, there are instances where the casing pressure sensor interface used for logging is incompatible with the reserved sensor interface of the choke manifold, or the casing pressure sensor is not installed properly or is incompatible. This can lead to risks such as casing pressure sensor clips falling off or flying out during the high-pressure testing of the well control device, as well as well control safety and equipment damage.

[0020] Based on these issues, the present invention will be further described below with reference to the accompanying drawings.

[0021] Figure 1 The schematic diagram shows the structure of the conversion device 100 for a pressure sensor according to the present invention.

[0022] like Figure 1 As shown, according to a first aspect of the present invention, a conversion device 100 for a pressure sensor is provided, mainly comprising a conversion body and a connector disposed on the conversion body. In the present invention, the connector includes at least one first connecting portion 21 and at least one second connecting portion 22, wherein the first connecting portion 21 can be used to connect to a throttling manifold interface (not shown), and the second connecting portion 22 can be used to connect to a pressure sensor (not shown).

[0023] The following is combined with Figure 1 The first embodiment of this utility model is introduced.

[0024] In such Figure 1 In the illustrated embodiment, the first connecting portion 21 and the second connecting portion 22 are located on two different planes in an orthogonal plane, and the first connecting portion 21 and the second connecting portion 22 are distributed in a non-coplanar manner, that is, the first connecting portion 21 and the second connecting portion 22 are not on the same coordinate axis. Therefore, this method allows for easier and faster matching with reserved pressure sensor interfaces or throttling manifold interfaces from different directions to achieve accurate connection, thereby solving the problem of improper installation.

[0025] In such Figure 1 In the illustrated embodiment, since the first connecting part 21 and the second connecting part 22 are distributed in a non-coplanar manner, it is easier to adjust the orientation of the casing pressure sensor to move it away from the direction of the worker, thereby further improving the safety of well operations.

[0026] In this invention, the first connecting part 21 is constructed as either an external thread or an internal thread, and the second connecting part 22 is also constructed as either an external thread or an internal thread. If it is an external thread, the thread is generally cylindrical and can be fixedly installed on the outer wall of the conversion body; if it is an internal thread, the thread is generally cylindrical and can be either fixedly installed on the outer wall of the conversion body or embedded inside the conversion body, depending on actual usage requirements.

[0027] Therefore, the fixed connection method using threaded connections can ensure the robustness between this device and the choke manifold interface and the casing pressure sensor. This can prevent the casing pressure sensor from falling off or flying away during the well control device pressure test, thus further ensuring the safety and effectiveness of the pressure test.

[0028] As is known in the art, the pressure sensor interface and the reserved sensor interface of the throttling manifold are usually fixed interfaces, meaning their size or model is fixed. Therefore, this device can be configured according to these fixed models to effectively solve the problem of mismatched thread types. Preferably, the fixed model interface of the pressure sensor interface is an M20*1.5 thread, while the fixed model interface of the reserved sensor interface of the throttling manifold (which is consistent with the throttling manifold interface mentioned in this document) is an NPT 1 / 2 thread.

[0029] Therefore, the first connecting part 21 in this invention is constructed with an NPT 1 / 2 thread, and the second connecting part 22 is constructed with an M20*1.5 thread. Simultaneously, the diameter of the first connecting part 21 is smaller than the diameter of the second connecting part 22. Thus, this device can be securely installed and matched with the choke manifold interface via the first connecting part 21, and securely installed and matched with the casing pressure sensor interface via the second connecting part 22. Therefore, during pressure testing, a strong connection can be formed between the choke manifold, the casing pressure sensor, and this device, thereby minimizing the risks of detachment, blowout, wellhead safety issues, and equipment damage.

[0030] In this utility model, such as Figure 1 As shown, the conversion device 100 for the pressure sensor also includes at least one plug 10. Preferably, the plug 10 is threaded. The plug 10 can be of several different sizes, thus enabling it to effectively match the first connection 21 and / or the second connection 22. Therefore, the plug 10 can effectively seal off any temporarily unused connections.

[0031] Because the casing pressure sensor interface (M20*1.5 thread) used for logging at the construction site cannot be properly matched with the reserved sensor interface (NPT 1 / 2 thread) of the choke manifold, this application provides a conversion device for the casing pressure sensor. This device can be individually matched with both the casing pressure sensor interface and the reserved sensor interface of the choke manifold, thereby enabling a stable connection between the casing pressure sensor and the choke manifold. This facilitates subsequent high-pressure testing and further ensures the safety of well control.

[0032] In this embodiment, the conversion body includes a first base 30 configured in an L-shape. A first connecting portion 21 is disposed on a side end of the first base 30. Notably, the first base 30 may have four side ends in different directions, and the first connecting portion 21 may be optionally mounted on at least one side end. For example, in Figure 1 In the embodiment shown, the first connecting part 21 is selected to be installed on the left side end of the first base 30.

[0033] In this embodiment, a first step 31 and a second step 32 with different heights are formed on the upper end surface of the first substrate 30, wherein the height of the first step 31 is greater than the height of the second step 32.

[0034] Preferably, the second connecting portion 22 is arranged longitudinally on the first step 31 and / or the second step 32. In other words, firstly, the second connecting portion 22 needs to be on a different coordinate axis from the first connecting portion 21; secondly, the second connecting portion 22 can be selectively installed on the first step 31 and / or the second step 32, for example as shown below. Figure 1 In the embodiment shown, the second connecting part 22 is installed on the first step 31, or the second connecting part 22 can be installed on the second step 32, or the second connecting part 22 can be installed on the first step 31 and the second step 32 respectively as needed.

[0035] Therefore, this method achieves the technical effect of simultaneously and stably connecting to the casing pressure sensor and the choke manifold, which helps with subsequent high-pressure testing and further ensures the safety of well control.

[0036] Figure 2 A specific embodiment of the conversion device for a pressure sensor according to the present invention is illustrated below. Figure 2 The second embodiment of this utility model is introduced.

[0037] In this embodiment, the conversion body includes a second base 40 configured in a columnar form. A first connecting portion 21 and a second connecting portion 22 are respectively disposed at both ends of the second base 40, and the first connecting portion 21 and the second connecting portion 22 are on the same axis.

[0038] Therefore, this method ensures that the throttling manifold interface connected to the first connection part 21 and the sleeve pressure sensor connected to the second connection part 22 are not in the same orientation (i.e., one facing upwards and the other downwards). Since the actual working pressure inside the joint may reach 0-110 MPa during operation, the orientation of the sleeve pressure sensor can be adjusted during installation to avoid personal injury.

[0039] Furthermore, since the first connecting part 21 and the second connecting part 22 can be individually matched with the casing pressure sensor interface and the reserved sensor interface of the choke manifold, the casing pressure sensor and the choke manifold can achieve a stable connection, which helps with subsequent high-pressure testing and further ensures the safety of well control.

[0040] In other embodiments of this utility model, the conversion body may also include a base structured into other structures, such as a T-shaped structure, a base-shaped structure, etc.

[0041] According to a second aspect of the present invention, a well control device is provided, comprising a conversion device as described above, a choke manifold connected to a first connection portion of the conversion device, and a casing pressure sensor connected to a second connection portion of the conversion device.

[0042] Compared with existing technologies, the advantages of this utility model are: This invention features a robust structure, moderate internal space, and ease of assembly and disassembly. The conversion device of this invention, through the first connecting part 21 and the second connecting part 22, can be individually matched with the casing pressure sensor interface and the reserved sensor interface of the choke manifold, respectively. This ensures a stable connection between the casing pressure sensor and the choke manifold, facilitating subsequent high-pressure testing. Therefore, it effectively prevents the casing pressure sensor from detaching or flying away during well control device pressure testing, further ensuring the safety and effectiveness of the pressure test.
