In view of the characteristics which has deep zones, low abundance, thin layer, ultra-low permeabil-ity , less reservoirs encountered by single well, and low daily production in the Third section of the Shahejie Forma-tion of Full2 Block. The deviated well technology was studied and application in exploration and development, by the analysis of the economy and technology difficulties. Field application shows that the deviated well technology both applies to Full2 Block reservoir and may have reference value to the ultra-low permeability reservoir for eco-nomic benefit development.%针对富112块沙三下段深层、低丰度、薄层、特低渗致密砂岩油藏的单井钻遇油层少、日产油能力低、难经济动用的特点,从技术和经济两方面入手,开展了利用斜井技术开发特低渗透油藏的试验研究,取得了较好的勘探开发效果.实践证明,斜井技术不仅解决了富112块沙三下段油藏的开发难题,而且对实现特低渗透油藏效益开发具有重要的参考价值.
