摘要
新疆油田石南21井区随着开发调整的逐渐进行,油田逐渐暴露出各主力层水淹强度不均等问题,本文通过油田已开发老井的物性参数与束缚水饱和度建立关系,从而对新加密井的原始含油饱和度进行解释,并与新加密井目前的含油饱和度进行对比,定量的解释了加密区的水淹情况。并用本方法对新疆油田石南21井区2个试验区进行解释验证,结果可靠,适用性强,可为同类油田后期的进一步开发调整提供借鉴。
With the gradual developing adjustment of Shinan 21 well area in Xinjiang oilfield,the problem that the flooded strength of each main layer not equal was exposed.In this papper,through established the relationship between Physical parameters and irreducible water saturation of the developed old well,the original oil saturation of the new infill wells were explained,and compared with the current oil saturation of the new infill wells,quantitatively explained the flooding situation of infill area. And use this method verify the 2 testing areas of Shinan 21 well area in Xinjiang oilfield.The result was reliable and strongly applicable,which can provide reference for further development and adjustment of the similar oilfield.
