Abstract
Disclosed is a well mouth oil gas recovery device of a producing well. The well mouth oil gas recovery device is composed of a lubricating oil cylinder and an oil gas recovery pump. The upper end of the lubricating oil cylinder is connected with the lower end of a pumping unit mule head actuating arm in a pin joint mode. The lower end of the lubricating oil cylinder is connected with the upper end of a piston rod of the oil gas recovery pump. The lower end of a cylinder body of the oil gas recovery pump is hinged on a base seat of a pumping unit. A lubricating oil outlet of the lower portion of the lubricating oil cylinder is connected with a lubricating oil inlet of the upper portion of the oil gas recovery pump through a hose. An oil gas inlet of the oil gas recovery pump is connected with an oil gas outlet of a well mouth of the producing well through a one-way valve I and a pipeline. An oil gas outlet of the oil gas recovery pump is connected with an outer conveying pipeline through a one-way valve II and a pipeline. Recovery efficiency can be improved by twice by adopting the working principle of single cylinder two-way air inflow and air outflow. A continuous lubrication device is added to the well mouth oil gas recovery device so that a piston and the piston rod can be lubricated continuously and sufficiently, and long-term continuous work of devices is ensured.
