Description

Technical Field

[0001] This utility model belongs to the field of single-well production venting operation, specifically relating to a single-well venting ignition device. Background Technology

[0002] Single-well venting is a critical operational step in natural gas production well opening, and employees frequently execute well venting commands according to production needs during daily operations. Current operating procedures require placing a flammable material at the vent and igniting it, then releasing the gas and igniting it before proceeding with the venting. However, due to the considerable distance between the vent and the edge of the blowout preventer, the following problems arise: First, the well site is uneven, making it difficult for employees to place fire sources, especially in winter when they are very likely to slip and fall. Second, the venting nozzle has a small diameter (DN50-80), which means there is not enough combustible material to release. After ignition, the fire source is easy to extinguish while personnel are evacuating to a safe distance, often requiring repeated operations. Third, the gas release operation is prone to producing too much gas, which can blow out combustible materials.

[0003] Therefore, during operation, the weather and the operator's skill level can affect the safety of the operator, posing significant safety risks. Utility Model Content

[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0019] It should be noted that in this utility model, the upper, lower, left, and right in the figure are regarded as the upper, lower, left, and right of the single-well blowout ignition device described in this specification.

[0020] Exemplary embodiments of the present invention are now described with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to fully and completely disclose the present invention and to fully convey its scope to those skilled in the art. The terminology used in the exemplary embodiments shown in the drawings is not intended to limit the present invention. In the drawings, the same units / elements are referred to by the same reference numerals.

[0021] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning.

[0022] This embodiment relates to a single-well venting ignition device, suitable for single-well venting outlets. Please refer to [link / reference]. Figure 1 The single-well blowout ignition device includes a housing 10, a battery boosting mechanism 20, and an ignition mechanism 30.

[0023] Specifically, the housing 10 has a hollow cavity, and the housing 10 can extend and retract to change its length.

[0024] like Figure 1As shown, the housing 10 is divided into a first end, a middle section, and a second end from bottom to top. The first end serves as a grip, also known as a handle, and is located at the bottom of the housing 10. The middle section consists of multiple telescopic rods that allow the housing 10 to extend and retract to change its length. The longest extension is 6 meters, and the shortest can be shortened to a convenient carrying length, such as 1 meter. The longest or shortest extension length can also be changed according to actual needs. The second end is located at the top of the housing 10.

[0025] It should be noted that the multi-stage telescopic pole in the middle section can be purchased commercially.

[0026] A spring wire 11 is installed in the middle section of the housing 10. The spring wire 11 serves as a conductor to connect the battery boosting mechanism 20 and the ignition mechanism 30. When the multi-stage telescopic rod in the middle section of the housing 10 is extended, the spring wire 11 extends accordingly; when the multi-stage telescopic rod in the middle section of the housing 10 is shortened, the spring wire 11 compresses accordingly. In other words, the spring wire 11 can change its state according to the extension and retraction of the housing 10 to ensure safe current transmission.

[0027] Continue reading Figure 1 The battery boosting mechanism 20 is installed inside the first end of the housing 10. To facilitate the installation of the battery boosting mechanism 20, the first end of the housing 10 can be a separate compartment, which can have a small hole for the spring wire 11 to pass through.

[0028] Please see Figure 2 The battery boosting mechanism 20 includes a battery box 21, a power switch 22, a charging interface 23, a boost converter 24, and a pulse switch 25. Specifically, the battery box 21 is used to install the battery. The negative terminal of the battery is connected to the power switch 22 via a wire, and the positive and negative terminals of the battery are connected to the charging interface 23 via wires. The charging interface 23 can charge the battery after an external power source is connected. The boost converter 24 is used to increase the voltage of the battery. The positive terminal of the battery is connected to the input terminal of the boost converter 24 via a wire, and the output terminal of the boost converter 24 and the power switch 22 are both connected to the ignition mechanism 30 via wires. The pulse switch 25 is connected in series on the wire between the boost converter 24 and the ignition mechanism 30.

[0029] In some embodiments, the boost pack 24 is used to boost the battery voltage from 3V to 10kV.

[0030] Before using the single-well venting ignition device, the power switch 22 needs to be turned off. Then, the multi-stage telescopic rod in the middle section of the housing 10 is pulled open and fixed one section at a time. Operator A holds the grip part of the housing 10 and places the ignition mechanism 30 1-2 cm away from the single-well venting port. The power switch 22 is turned on and the pulse switch 25 is pressed. The ignition mechanism 30 starts to discharge. At this time, operator B opens the valve, and the natural gas comes out of the venting port and is immediately ignited, starting the venting operation.

[0031] The retractable housing 10 allows the single-well blowout ignition device to be shortened and placed in a vehicle or other device for easy carrying when in standby mode. When needed, simply pull out the retractable section of the housing 10, and the operator only needs to press the power switch 22 and pulse switch 25 inside the battery booster mechanism 20, which can effectively prevent accidental operation and injury.

[0032] The ignition mechanism 30 is used to ignite natural gas from the single-well vent. The ignition mechanism 30 is installed at the second end of the housing 10, and the battery boosting mechanism 20 is connected to the ignition mechanism 30 via a wire. Specifically, the ignition mechanism 30 includes a bracket 31, an insulating ceramic sleeve 32, and an ignition electrode 33.

[0033] Please see Figure 3 The bracket 31 is installed at the second end of the housing 10, the insulating ceramic sleeve 32 is fixed to the bracket 31, the ignition electrode 33 has an ignition end and an end, the ignition end is used to discharge and ignite the natural gas at the single well vent, and the end is inserted into the insulating ceramic sleeve 32 and connected to the spring wire 11 through a wire.

[0034] Specifically, the two ends of the two ignition electrodes 33 are respectively connected to the spring wire 11 through wires, that is, there are two wires, and the two wires are connected to the spring wire 11 at the same time.

[0035] Figure 3 The image shows a pair of ignition electrodes 33, each equipped with a pair of insulating ceramic sleeves 32.

[0036] When ignition and discharge are required, open the multi-stage telescopic rod in the middle section of the housing 10, align the ignition electrode 33 with the ignition part (discharge port), turn on the power switch 22, hold the housing 10 steady, and click the pulse switch 25. The ignition electrode 33 will start to discharge to achieve arc ignition. With arc ignition, there is no need to worry about the fire source being blown out in windy weather.

[0037] In some embodiments, when the ignition mechanism 30 ignites the natural gas from the single well vent, the ignition end of the ignition electrode 33 is placed 1-2 cm away from the single well vent.

[0038] The single-well venting ignition device provided in this embodiment does not require the operator to place a fire source near the vent. The operator only needs to extend the housing 10 and align the ignition end of the ignition electrode 33 with the vent. The ignition electrode 33 uses an electric arc for ignition, so there is no need to worry about the fire source being blown out by windy weather.

[0039] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
