Description

Technical Field

[0001] This utility model relates to the field of oil and gas drilling and production equipment technology, specifically to a solar ignition device. Background Technology

[0002] During oil drilling, when drilling reaches a high-pressure oil and gas layer, if the drilling fluid column pressure is lower than the layer pressure, the high-pressure oil and gas flow will invade the wellbore and gradually rise towards the wellhead, potentially causing a blowout or well kick. In this situation, drilling workers will shut off the blowout preventer and take appropriate measures such as throttling and venting. The directly vented natural gas needs to be ignited; otherwise, if it mixes with air in a certain proportion, it poses an explosion risk. Furthermore, the vented gas contains harmful gases such as H2S, which can endanger human lives. Currently, some gas wells are located in remote areas, making external power connections difficult or requiring long power cables. Using batteries also presents charging challenges, increasing the workload for workers. Additionally, existing ignition guns are not easy to control the flame direction during ignition, especially in harsh environments, resulting in a low ignition success rate. Utility Model Content

[0003] This invention aims to solve the problem that some existing ignition devices operate in special environments and are inconvenient to connect to external power sources, and proposes a solar-powered ignition device.

[0004] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows:

[0005] A solar-powered ignition device includes a control skid, an ignition gun, an oil tank, and an ignition gas source. The control skid includes a skid body, a solar panel on the top of the skid body, and a battery connected to the solar panel inside the skid body. The battery supplies power to the electrical components and ignition gun mounted on the skid body.

[0006] The ignition gun includes a burner head and an injector installed inside the casing. The burner head is connected and fixed to the casing. A conductive rod is installed above the casing. The ignition head, connected to the conductive rod, extends into the casing and is positioned above or in front of the nozzle of the injector.

[0008] Furthermore, the burner head has a bent structure, and the burner head is fixed to the casing by a rotating flange. The direction of flame jet during ignition can be changed by adjusting the installation position of the rotating flange.

[0009] Furthermore, the ignition head and the conductive rod are connected by an elbow.

[0010] Furthermore, a support base is provided on the outside of the casing.
