摘　　要：为了扩大单井控制面积,提高储层动用程度,增加单井产量,在哈萨克斯坦R油田特低渗、难动用区块开展了水平井分段酸压的先导性试验。根据地质油藏、钻井、录井、测井等结果,确定了完井管柱结构及工具位置。为了提高段内均匀改造程度,使用了纤维暂堵转向工艺,并对施工压力、排量、所需水马力等参数进行了优化。微地震监测结果表明,每段都形成了独立的裂缝网络,达到了分段改造的目的。投产后取得了明显的增产效果,说明水平井多级分段酸压工艺对开发该油田致密薄层碳酸盐岩油气藏具有较好的应用前景。In order to increase single well controlling area,improve formation developed level and producing rate,a pilot test of multiple staged acid-fracturing was developed in R oilfield ultra low permeability block,Kazakhstan. Based on material of oil-field geology,oil reservoir,well drilling,mud logging,well logging and so on,well completion string component and instrument position are determined. For getting a more homogeneous stimulated profile,temporary plugging and diverting technology with fiber are applied and parameters such as treating pressure,pumping rate,horse power needed are optimized. Micro seismic results show that separate fracture network is formed in every section,which achieves the purpose of multiple staged acid-fracturing. After stimulated,this pilot well gets a satisfactory oil production,which means multiple staged acid-fracturing technology is suitable for this oilfield tight thin carbonate reservoir.
