中原油田水平井技术应用及发展方向

Application and Development of Horizontal Well Technology in Zhongyuan Oilfield

通过分析国内外水平井技术发展状况及目前技术水平,结合中原油田油藏结构和地层特点,着重分析了中原油田运用水平井技术的高难度性、复杂性和高风险性。通过介绍中原油田水平井的设计和施工实践,阐述了水平井技术在中原油田的适应性和工艺特殊性,描述了中原油田高难度水平井钻井、完井工艺技术,水平井施工设备配套技术,井眼轨迹控制技术,钻井液技术,井下安全钻井工艺技术等方面的成功和不足,并结合中原油田油藏结构特性,地质复杂特点及现场施工经验教训,给出了中原油田水平井技术施工和技术发展的措施和建议,希望为中原油田水平井技术发展提供借鉴。

Through the analysis to the developing status of technology and the present level of horizontal drilling in domestic and overseas, this paper analysis the difficulties and complexities and high risks of horizontal drilling technique using in Zhongyuan Oilfield. With introducing horizontal hole plan and practice, the authors describe the adoption and special of the technique in Zhongyuan Oilfield and give some helpful ideas, such as in drilling, completion, hole trace controlling, mud system and down hole safety.
