摘　　要：川口油田属典型的低压、低渗、低产油藏,纵向上表现为多套小层叠合,开发过程中油井层间压差矛盾较为突出,层间干扰大,严重影响油田的开发效果。为此,试验应用了分层采油技术,并取得了提液增油的效果,表明分层采油技术在该区具有较好的适应性,能解决各层动用程度不均的问题,有效缓解多层油藏开采时的层间矛盾,对油田高效开发发挥积极作用。Chuankou Oilfield is typical of low formation pressure,low permeability,and minor production.There are multiple sets of small lamination existing longitudinally,It shows that interlayer interference was serious and had a serious impact on the Oilfield exploiting.Therefore,the separate layer production technology was tested in Chuankou Oilfield,the fluid production increasing significantly indicated that the separate layer production technology had preferable flexibility in this area.The technology could not only solve the problem of motion level in non-uniform of each layer but also remit the interlayer contradiction during the exploiting of the multi-layer reservoir,which had positive effect on high efficiency developing of the oilfield.
