STUDY AND APPLICATION OF SD-1 DEEP PROFILE CONTROL AGENT

A kind of deep profile control agent was developed according to the problems exiting in field such as higher cost of general agent and shorter disposal radius. This kind of reality gel was formed using bigger molecular weight polypropylene acidamide as main material, put in many crosslinker, stabilizer and raterder. This paper mainly discusses the effect mechanism, affect factor and the technology using in fields. The paper also discusses the field test in Zhongchakou Oilfield and Erlian Oilfield. It was testified that this kind of gel agent has a longer crosslinking time, lower cost, longer disposal radius and simpler construct technology.
