Description

The utility model relates to the oil and gas industry, namely for the remote ignition of hydrocarbon gases on flare lines of gas, gas condensate and oil bushes.

A device for burning oil gases [RU 96123631, published 02.20.1999] containing a supply gas pipeline with a valve, a device for igniting oil gases and a torch burner, is equipped with a combustion chamber, regulated by a source of longitudinal electric field with a field strength of at least 0.5-1 kV / cm and a device for applying a longitudinal electric field to the flame torch at a distance greater than the size of the flame sufficient to prevent electric breakdown of the source of the electric field through the torch of combusted oil the basics and is supplemented by a source of a rotating transverse electric field, and electrodes supplying these longitudinal and transverse electric fields to the combustion zone, the source of the longitudinal field being connected between the burner and the longitudinal electrode placed at a distance above the flame of oil gases, the rotating electric field device contains a three-phase high-voltage adjustable a frequency converter with an output phase voltage of at least 10 kV, and three heat-resistant electrodes located in the combustion zone, more specifically in cross section plane to the torch and outside the torch, with a spatial shift of 120 °, to which the high-voltage outputs of the three-phase frequency converter are connected. As the ignition device, the central electrode itself with a needle ring at the lower end, placed in the ignition mode of oil gas, at a minimum distance from the gas-air burner, was used, and the governing body of the mechanism of movement of the central electrode in the mode of electric ignition of gas is connected to the mode optimizer via a flame detector and a sensor secondary current of a high voltage converter.

A known tip of the flare unit [RU 2344345, published January 20, 2009], comprising a flare tip, a standby burner, a standby burner ignition chamber, an electric igniter and ignition electrodes of an electric igniter, according to the invention, an electric ignitor is located between the torch tip and the standby burner so that the axes the torch tip, the electric igniter and the pilot burner are located in the same plane, and the spark gap of the electric igniter is located in the said plane above the lower intersection point of the continuation of the forming cones of the flare tip diffusers and the standby burner, while the spark gap is located within the spray cones of the flare tip and the standby burner, and the axis of the electric igniter is located between the axes of the tip of the flare tip and the standby burner.

Known horizontal flare unit (AGG), designed to burn gas with the presence of fluid from the wells of the loops, containing a unit for reducing and preparing fuel gas for the pilot and standby burners, a set of cables to the burner device (cable for a thermocouple flame control and cable for the spark plug); torch control unit, including models with automatic control systems based on a modern controller with the ability to control from the automatic control system. The installation is mobile, with a small mass of blocks, can serve a large number of wells and with an autonomous ignition system (with a battery ignition unit) - for wells and clusters without power supply [http://tyumenniigiprogaz.gazprom.ru].

However, all known devices have several disadvantages: high metal consumption, expensive installation work (since the systems are stationary); Electricity 220 V is required for ignition. For a standby burner, it is necessary to prepare natural gas (drained and without mechanical impurities, that is, it is necessary to additionally prepare gas on a cluster of gas wells) or use a propane-butane mixture (connect a propane cylinder), given that it is necessary to install on each cluster of wells (on one field in 35-40 bushes), then the cost of equipment and metal consumption increases sharply and requires additional costs for equipment maintenance.

The technical problem associated with the use of the proposed device is aimed at improving the safety of the process of burning hydrocarbon gas on flare lines of gas, gas condensate and oil pockets at, as well as in the process of cleaning the bottom-hole zone of wells (after well repair and drilling), eliminating hydrated and liquid plugs and eliminate the possibility of methane entering the atmosphere during research on gas and gas condensate wells.

The technical result consists in expanding the range of devices for remote ignition of hydrocarbon gases in a flare.

The technical result is achieved by the fact that the device for remote ignition of hydrocarbon gases on a torch contains a quick-detachable mount in the form of a clamp with ignition electrodes connected to a system of start buttons and an ignition start block.

The utility model is illustrated by a detailed description and illustrations, which depict:

FIG. 1 - shows a mobile device for remote ignition of hydrocarbon gases in a flare: 1 - start button (enable / disable); 2 - ignition start block; 3 - ignition electrodes; 4 - connecting cable (220; 24; 12 V); 5 - high voltage protected cable; 6 - clamp for attaching the electrodes to the flare line (pipeline); 7 - flare line (pipeline).

The essence of the utility model is not limited to the description below.

Implementation of a utility model.

The device consists (Fig. 1) of a quick-detachable fastening in the form of a clamp 6 for attaching to the flare line 7 (pipeline), ignition electrodes 3, a system of start buttons 1, ignition start unit 2 (Fig. 2), a set of connecting cables: cable 4 ( 220; 24; 12 V), high-voltage shielded cable 5.

A mobile device for the remote ignition of hydrocarbon gases works as follows.

The device is mounted on the flare line 7 of the wellbore using a quick-detachable fastening in the form of a clamp 6 with ignition electrodes 3 (Fig. 1). The connecting cable 4 is connected to the 220 V electric network and hydrocarbon gas is supplied through the flare line 7. The system is turned on by the start button 1, the electric current is supplied through the connecting cable 4 to the ignition start unit 2 (Fig. 2), where it is converted to high voltage pulses. Next, the pulse through the connecting high-voltage cable 5 is supplied to the ignition electrodes 3, where an electric arc arises, which ignites / ignites the hydrocarbon gas.
