초록 ▼

Apparatus for production of liquid from wells such as petroleum wells includes well pipe that extends from the surface downwardly to the level of liquid standing within the well. A string of production tubing is positioned within the well pipe with the annulus between the production tubing and well pipe defining gas supply means that is interconnected with a source of compressed gas. At the lower portion of the production tubing is located aspirator means having a gas injection element defining a gas jet passage which is in communication with the gas supply annulus. The gas injection element is oriented to direct an upwardly flowing jet of pressurized gas which is directed into the lower restricted portion of a venturi that extends upwardly from the aspirator means into the production tubing. The aspirator means also defines a liquid flow passage that is in communication with liquid standing within the well. The liquid flow passage means and the gas injection jet have confluence within the restricted portion of the venturi whereby the jet of compressed gas aspirates the liquid and transports the liquid to the surface for ultimate handling. The production system is capable of being employed for production of single wells or production of plural wells in parallel or serial manner. The production system is also usable in conjunction with a lubricant system for injecting lubricant into the gas that is injected into the well and a chemical injector system for injecting any suitable chemical means into the upper discharge portion of the production tubing.
