The gathering and processing technology for CO2 flooding produced fluid is a key issue closely related to the technical feasibility for recovery enhancement by CO2. An optimization and transformation program for ground engineering for CO2 flooding pilot test in Yaoxi block of Yaoyintai oilfield has been developed based on analysis of properties of the produced fluid and associated gas, adaptability for the gathering system, existing system improvement and processing for associated gas. This paper suggested that to minimize engineering investment and improve economic benefit of the project, it is a priority to analyze the adaptability of existing systems and access the feasibility using existing facilities in CO2 flooding pilot test at existing oilfields.
