Study on water control technology for thin layer bottom water drive reservoir in Luliang Oilfield

This paper investigates the water production characteristic for bottom water drive reservoir and water shut-off method for effective controlling water production.The experimental study was conducted to analyze the reservoir performance through different water shut-off methods.The best water shut-off method has been screened for effective conformance treatment,water control,improving oil recovery and decreasing water cut.The water shut-off method through polymer injection to form an isolated zone to block the water coning was selected.The operation procedure related to this method are also demonstrated in this paper.
