| 摘 要： | 低渗透油藏开发中,油水渗流时的启动压力现象普遍存在,在开发过程中必须依据油藏的油水启动压力梯度规律来确定合理的注采井距。将启动压力梯度规律与渗流理论相结合,确定了井距与动用储层渗透率下限的关系及井距与动用储量百分数的关系,从而有效指导井网加密调整工作,可为低渗透油田开发确定合理井网密度提供理论依据。

| Abstract: | In the development of low permeable oil field,threshold pressure phenomenon generally exists when oil and water filtrating,advisable injector producer distance must be defined according to threshold pressure gradient law of oil and water.Combing threshold pressure gradient law and filtrating theory,relationship between well spacing and permeability plugging of producing layer and relationship between well spacing and producing reserves percentage were defined,which can guide well pattern thickening modifyin... |
