中原油田第一口薄产层侧钻水平井轨迹控制技术

The Well Track Control Technology of the Thin Productive Reservoir Directional Horizontal Drilling in Zhongyuan Oilfield

濮1-侧平239井是中原油田第一口筛管完井的139.7mm套管开窗侧钻水平井。结合该井的地质情况和井身质量要求,分析了井眼轨迹控制的难点,提出了控制方案,介绍了井眼轨迹控制的全过程。总结了薄产层侧钻水平井的经验教训,有一定的借鉴作用。

Pu1-239 well is the first 51/2″casing directional horizontal drilling in the Zhongyuan oilfield using the screen pipe completion. The Pu1-239 well drilled successfully shows that the casing directional horizontal drilling technology has made further progress in the Zhongyuan oilfield. Incorporating the well geology and borehole quality considerations, the author analyzes the difficulties of the well track control and gives a applicable control program. After the well path control process introduced in detail, the author summarizes the thin productive reservoir directional horizontal drilling construction experiences.
