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 Oilfield is located in the economically developed Yangtze River “Golden Triangle” area. The area has dense surface water networks, dense villages, high cost of drilling and land requisition, and high requirements for environmental protection. With the development of underground faults and small reservoirs, Jiangsu Oilfield is a complex small fault block Oilfield, development difficult. In recent years, due to the extensive application of horizontal well technology, the development of Jiangsu oilfield has been promoted. The basic geological characteristics of Jiangsu complex small fault block oilfield are expounded. The status of the test, research and application of horizontal well technology in Jiangsu oilfield is systematically introduced. Application of typical reservoir effect, put forward the application of horizontal well understanding and suggestions.
