摘要
根据多年来修正研究的低渗油藏油水两相非线性渗流理论方法,以长庆油田安塞王窑中西部长6特低渗注水油藏B井区为例,利用现有的试井资料的分析研究,成功地进行了油水井渗透率平面变化特征,以及渗透率、表皮系数、地层压力随时间动态变化特征的定性、定量分析。该方法和结果已用于低渗孔隙-裂缝型注水油藏,以及定性分析井间连通情况、分析注采平衡、判断渗流特性,为合理选择注水时机、强度提供依据。
Under condition of the revising study of non-linear flow in porous media theory and method with two-phase of oil and water for low permeability reservoir,and taking examples of Changqing oilfield Ansai Chang6 special low permeability water flood reservoir using Wangyao middle west chang6 low permeability,by use of the present well testing material,permeability plain change characteristic of oil and water well,and qualitative and quantitative analysis of the dynamic change of the permeability,skin factor,stratum pressure with time characteristic are conducted successfully.This method and result can be used in low permeability pore-fracture-style water flood reservoir,and qualitative analysis well-to-well connection situation,analysis water flood production balance,judging flow in porous media characteristic,and for reasonable select water flood opportunity,strength provide basis.
