【摘要】 在查阅了大量的静态资料和开发动态资料，详细了解南二、三区西部开发区不同井网的油层地质沉积特征和区块开发状况。在此基础之上，本文主要针对分层注水井压力落差试井的数据受由续流量所引起的水嘴损失和井筒储存效应的双重影响，直接用常规解释方法解释误差较大，不能利用早期资料对每一层进行单独解释的情况，研究了南二三区西部分层注水井压力落差试井的分层动态参数解释方法，根据水嘴损失并运用了恢复期续流段压力校正方法，并通过对比分析，得出不同地层条件下的续流量递减规律，进而得到水嘴后的分层压力降落曲线数据。通过对分层注水井压力落差试井数据进行校正，最终得到一条相关系数最高的直线段，利用常规试井解释方法解释地层压力等动态参数。通过与分层测压资料进行对比分析，验证了该方法能够消除了水嘴损失和部分井筒储存的影响，得到能够满足工程要求的分注井的分层动态参数。并给出了该方法在南二三区高台子油层高压区治理的应用实例。更多还原

【Abstract】 According to the reservoir static data and developing dynamic data, knows the oil lay geologic deposit characters of the different layout of the well pattern in the west of south 2-3 zone and the developing stastus of the zone.Primarily,because the pressure fall well test data of layered water injection well is affected by the loss of flow plug, The effect of well bore storage are both created by the continuous flow.The common interpretation methods can create more error.So we can not use the early period data to interpret every layered water injection well pressure fall well test on south 2-3 zone. On the basis of flow plug loss and use the pressure corrective method on the continuous flow of resume period.By contrast and analysis,draw the conclusion that under the different strate conditions the continuous volume of flow is degressive. And get the data of layered pressure fall curve behind the flow plug. By the correction of pressure fall well test data of layered water injection well at last we get a straight line in which the relative coefficient is the highest, we can use conventional well tset interpretation methods to interpret dynamic parameters such as strata pressure. Analysis and compare with layered test-pressure data.we can prove that this method can eliminate the loss of flow plug and partly effect of the wellbore storage, can get the layered dynamic parameters of the layered water injection well that satisfied the demand of the engineering.and we give out the application examples using this method to interpret the excessive high pressur area of south 2,3 zone Gaotaizi oil layer.更多还原
