HW60 0 1井是哈萨克斯坦国肯基亚克油田的第一口水平井 ,该井目的层是侏罗系砂砖组 ,属浅层超稠油。由于热采工艺要求抽油机有杆泵必须安装在Φ2 4 4mm技套内 ,并且距主力油层顶界小于 2 0m、水平段井斜 93.2°,能较大的提高抽油机的工作效率 ,而采用三靶水平井技术设计井眼轨迹可满足此要求。该井投产后日产原油产量是直井的 1 5倍 ,经济效果显著。本文介绍了该井钻井工艺的技术难点、采用的措施和轨迹控制技术。
The HW60 0 1 well is the first horizontal well in the Kenkiyak oilfield in Kazakhstan, where the target formation is Jurassic sand bricks and belongs to shallow super-heavy oil. As the thermal recovery process requires pumping rod pump must be installed in Φ2 4 4mm set, and from the top of the main reservoir is less than 20m, the horizontal section 93.2 ° inclination, can greatly improve the working efficiency of the pumping unit, The use of three target horizontal wellbore trajectory design to meet this requirement. The well put into operation Nissan crude oil production is 15 times the vertical well, the economic effect is remarkable. This paper introduces the technical difficulties, the adopted measures and the trajectory control technology of this well drilling technology.
