The liquid hydrocarbon recovered from casingheadgas by adsorption, compression, or refrigeration. Casingheadgas is the gas recovered at the surface from an oil well.
This article presented the research on matching technology of casinghead and gas-producing wellhead for guaranteeing the safety of drilling and production test operation.
For improving need assembling the casinghead, the cutting casing pipe on project, we have designed the device of cutting casinghead to change unfavorable factors using acetylene gas to cut case.
