Abstract: Buried Hill limestone oil and gas reservoirs are mostly storage sour gases such as hydrogen sulfide and carbon dioxide, which brought a lot of challenges to the safety operation of oil-testing,environmental protection and quality. For these problems, the process scheme, tubing material, supporting tools, kill fluid performance and ground testing process were studied, introduced a set of oil（gas）-testing technology for adaptatiing to the high content of sour gases limestone reservoir. The technology with a trip column completed processes of perforating, seeking natural capacity, acid fracturing and sealing layer, and meeted the requirements of a long trial exploitation. Field application shows the technology safe and reliable, reducing labor intensity and operational risk. The technology is a good reference for oil（gas）-testing of buried Hill limestone oil and gas reservoirs.
