The invention discloses an automatic charging device of a foam discharging rod on a wellhead. The automatic charging device of the foam discharging rod on the wellhead comprises a connecting body (4), an upper end cover (17) and a lower end cover (1), wherein the connecting body (4) is provided with a charging through hole and a connecting shaft through hole, and the connecting shaft through hole is internally provided with a rotatable connecting shaft (2); the upper end cover (17) and the lower end cover (1) are respectively provided with through holes which correspond to the position of the charging through hole; an upper sealing disk (5) which can rotate with the connecting shaft (2) is clamped between the upper end cover (17) and the connecting body (4), and the upper sealing disk (5) is provided with an upper through hole; a lower sealing disk (3) which can rotate with the connecting shaft (2) is clamped between the lower end cover (1) and the connecting body (4), and the lower sealing disk (3) is provided with a lower through hole; and the upper through hole and the lower through hole are symmetrical relative to the connecting shaft (2) in a projection within a plane perpendicular to the connecting shaft (2). The automatic charging device disclosed by the invention can ensure that the foam discharging rod can be automatically charged into a well through structural design.
Description
technical field [0001] The invention relates to the technical field of wellhead foam rod filling technology, in particular to an automatic wellhead foam rod filling device. Background technique [0002] During the exploitation of natural gas, due to the high pressure of the geological formation, the water has been gasified under high pressure. When it is pumped out from the geological layer, the pressure gradually decreases, and the gaseous water is liquefied from the gaseous state to liquid water under the condition of reduced pressure. The discharge agent reacts to generate foam, which is discharged from the production wellhead. [0003] In the prior art, the method of manually delivering the foaming agent has been adopted, and the work is labor-intensive, especially in winter when the temperature is relatively cold, and the mining of natural gas is unstable and inefficient. In order to improve the efficiency of natural gas extraction, the stability of natural gas extrac...
