Gas Lift Chamber Purge and Vent valve and Pump Systems |
摘要 |
The present invention is directed to producing fluid from an oil or gas well by means of a combination intermittently filled down hole chamber accumulation device and a connected upper continuous gas lift flow system, separated by an inline one-way reverse flow check valve. A two-way purge and vent valve controls the distribution of high pressure gas. The two-way valve first injects high pressure gas into the chamber accumulation device to displace the fluid from the chamber into the continuous flow conduit. The two-way valve then vents the residual high pressure gas from the chamber into a separate low pressure conduit to the surface. The valve also provides high pressure gas to the continuous flow conduit to assist in the production of the fluid.
