摘　　要：江苏油田地处经济发达的长江"金三角"地区,该地区地面水网密布、村庄密集,钻井征地费用高、环保要求高;地下断层发育、油藏规模小,属我国东部复杂小断块油田,开发难度大。近年来,由于水平井技术的广泛应用,推动了江苏油田的发展,文章阐述了江苏复杂小断块油田的基本地质特点,系统介绍了水平井技术在江苏油田试验、研究和应用状况,分析了典型油藏应用效果,提出了对水平井应用的认识和建议。Jiangsu oilfields locate in economically developed Yangtze Golden Triangle areas and has variegated rivers and villages.This area also faces high cost for well drilling and land acquisition as well as environment requirement.Faults develop under the ground.The scale of oil deposit is small.This area is eastern complex fault block oilfields and difficult to exploit.In recent years horizontal well technology is applied widely,motivating the development of Jiangsu oilfields.The paper elaborates the basic geological features of Jiangsu complex fault block oilfields,systematically introduces the experiment, research and application situation in Jiangsu oilfields,analyzes the effect of typical oil reservoir,and brings about advifces of horizontal well application.
