Abstract

The invention discloses an oil pumping well casing gas controller which comprises a shell. The shell is a section of thick-wall pipe. A gas inlet is formed in the lower end of the shell. A baffle is arranged at the gas inlet. The baffle is mounted on the inner wall of the gas inlet through a hinge and matched with the gas inlet. A hole communicating with the gas inlet is formed in the side wall ofthe shell. A gas pressure sensor is arranged on the surface, making contact with the gas inlet, of the baffle. The gas pressure sensor is connected with a computer through a wireless network. When the gas pressure is greater than the connection pressure of the baffle, the baffle is opened, and gas enters the baffle and then is recycled; and when the gas pressure is decreased, the baffle is closed, and thus stopping is conducted. The oil pumping well casing gas controller is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to oil recovery technology, in particular to a casing gas controller for pumping wells. Background technique [0002] At present, the recovery and utilization of natural gas produced from the casing in the production process of oil pumping wells in various oil fields generally adopts the method of connecting the gas pipeline between the wellhead casing head and the oil pipeline; although this method can effectively recover natural gas, it increases the cost. Wellhead equipment also brings inconvenience to oil well maintenance and winter wellhead insulation. Contents of the invention [0003] In view of the above defects or deficiencies, the object of the present invention is to provide a casing gas controller for pumping wells. [0004] Technical scheme of the present invention is: [0005] It includes a casing, the casing is a section of thick-walled pipe, a gas inlet is opened on the lower end of the casing, a baffle is arra...
