基于压力恢复曲线的油井堵水决策技术
Decision-making technique of oil well water plugging based on pressure buildup curve
摘要
Abstract
The mathematical model and decision-making index (fPBD) of water shutoff can be established using the seepage mechanics theory and pressure buildup curve.The target wells were selected based on the fPBD value,water cut rising index,remaining oil saturation and water shutoff comprehensive decision value obtained by fuzzy evaluation method.Seven production wells in KD521 block were chosen.The results show thatfPBD is related to water permeability,which can be considered as the foundation of water shutoff decision-making.The decision method of selecting well is characterized by taking into account all the factors,data easy to be obtained,and precise decision.The results agree well with that of experienced well selection method.关键词
