The clustering analysis about casing damage and sidewall collapse in six and seven area of Tahe oilfield

摘要

By censusing and Sorting the current datas of casing damage and sidewall collapse wells over six and seven area of Tahe oilfield, analyzed all kinds of influence factors and technical countermeasures. Downhole liquid level height is the breakthrough point when considering the stress state of casing and sidewall. And calculate critical level value of casing damage and sidewall collapse. Along with the deep pumping technology of Tahe oilfield development, it's necessary for Real-time monitoring well liquid level height to guarantee the working level cannot achieve critical height.
