摘　　要：从理论上分析，油田进行小井眼定向井的开发将大大降低开发成本，其应用与推广将给油气资源的开发带来巨大的经济效益和社会效益。但是目前小井眼定向井钻井速度仍然很慢，制约了该项技术的推广发展。长庆油田分公司2008年计划实施“2吨区”（0．3×O0^3μm^2）工程，针对油田公司的开发方案开展油井小井眼钻井配套技术研究，并进行了3口井钻井试验。本文针对钻井情况进行了详细分析，分析了小井眼定向井的难点及原因，并提出了具体建议，对后续“2吨区”小井眼进一步试验具有重要意义。Theoretically, oilfield development with directional slimholes （wells with small diameters）will dramatically decrease the development cost. Application and popularization of directional slimholes in oilfield development may bring great economical and social benefits to development of oil and gas resourees. However, a directional slimhole is still of low drilling velocity to restrict development and promotion of this technology. “2-ton area” （0.3 millidarcy）project was intended to implement by PetroChina Changqing Oilfield Co. Research of supporting technologies was made for drilling oil slimhole directing at development solution of the Oilfield Company and drilling test was made on three wells. This articles in detail analyzes them according to drilling situation, analyzes difficuhies and causes of directional slimhole, provide specified recommendations, which is of great significance for further testing slimholes in future “2-ton are”.
