摘　　要：为了改善油藏整体开发效果 ,决定在胡状集油田进行 SD化学驱油试验。文中主要介绍了 SD驱油体系及其矿场先导性试验。经过几年的现场试验 ,累积增油 1.5× 10 4t,投入产出比 1∶ 4.83。该技术的成功应用 ,为化学驱在“三高”油藏 (高温、高矿化度、高二价金属离子 )的应用提供了一定的宝贵经验。The buried depth of Huzhuangji oil reservoir is about 2 000 m, its temperature is about 70~90℃; the salinity of formation water is above 10×10\+4 mg/L; The concentration of Ca\+\{2+\} and Mg\+\{2+\} is 5 000~6 000 mg/L. After ten-year waterflooding development, the water content of the reservoir is above 85%,even 90% in some tracts. The test of SD oil displacement system is right to improve the mass development effictiveness. The accumulative oil prodution by this test is 1.5×10\+4t, the input-output ratio is 1:4.83. the successful application of this provides an useful expriences for development of 'three high' (high salinity, high temperater, high divalent metallic ion) reservoir.\;
