摘　　要：北努拉里油田位于哈萨克斯坦南图尔盖盆地,是一个典型低渗透油藏。该油藏岩性致密、孔喉细小、渗流阻力大,油层跨度大。通过对多尚组J_2ds油藏开发方式论证,认为压裂方式效果最好;J_2ds_3和J_2ds_4层先合层生产,择机上返J_2ds_(1+2)可取得较好开发效果;油田多采用反九点法注水井网,综合确定合理井距为210m小井距开发效果好。North Nuarly oilfield located in South Turgay Basin in Kazakhstan,is a typical low permeability reservoir. The reservoir has features of tight lithology,tiny pore throat,high filtration resistance and formation of large span. Through the analysis of reservoir development in Doshand J_2 ds,it is considered that fracturing is a bestway. The production of J_2ds_3 and J_2ds_4 at first and then J_2ds_(1+2) can get better development effect;it is used the inverted nine-spot well pattern in the oilfield and the well spacing for 210 m can get good development effect.
