The invention relates to a device for introducing a solid foam-generating substance into the natural gas wells. According to the invention, the device represents a tight enclosure mounted on the flow head and comprises two ball or plug straightway valves (1 and 2) with a diameter of 2'' for various pressures, depending on the nominal pressure of the flow head, a section (8) of extraction pipe with a diameter of 2'' and a length which is at least equal with the length of the solid foam-generating stick mounted between the two valves (1 and 2), a reducing coupling (9) intended for passing from the diameter of 2'' of the device to the nominal diameter of the flow head, a flange (10) for mounting the device onto the flow head, a 2'' plug (7) for securing the device and the flow head when the device is not in use and a 1 /2'' blow valve (6) mounted on the plug (7), where the solid foam-generating substances are introduced into the natural gas wells by closing a valve (5), opening the valve (6), detaching the plug (7), opening the valve (1), introducing the solid foam-generating substance, closing the valve (1), opening the valve (2), waiting for 2 min in order to allow the solid foam-generating substance to fall into the gas well, closing the valve (2), opening the valve (5), mounting the plug (7) and closing the valve (6). |
