Study on the Wellhead Sampling Method for SAGD of Heavy Oil

Aiming at the existing problems of the SAGD sampling method, based on the sampling SAGD production liquid requirements, through the analysis of advantages and disadvantages of extraction pipeline sampler and DC cooling type sampler, the bypass pipeline sampler is finally designed which meets the requirements of SAGD sampling. The sampler is suitable for the water content of SAGD sampling, and provides some guidance for the development of SAGD matching technology.
