摘　　要：引入井数替代比的概念求取在不同含水率条件下直井与水平井的替代系数,解决以往合理油水井数比计算方法只适用于直井井网的问题,建立了直井与水平井联合井网开发油藏的合理油水井数比计算方法,可对此类开发方式油藏的注采结构调整潜力进行分析。渤海A油田应用表明,该方法能很好地解决直井与水平井联合井网开发的油藏合理油水井数比计算问题,并分析注采结构调整后的提液潜力。The concept of well number substitution ratio was introduced to obtain the substitution coefficient of vertical well and horizontal well under different water content conditions, which solved the problem that previous rational oil and water well number ratio calculation method was only applicable to the vertical well. A reasonable number ratio calculation method of oil and water wells for developing oil reservoir in combined well pattern with vertical well and horizontal well was established. The potential of the adjustment of injection and production structure for this type of reservoir was analyzed. Its application in A oilfield of Bohai showed that this method well solved the problem of calculating the ratio of oil-water wells in vertical horizontal wells during combined well pattern development, and the potential of liquid recovery after adjustment of injection production structure was analyzed.
