水平井水平段轨迹控制技术探讨

Discussion on the Trajectory Control Technology of Horizontal Section of Horizontal Well

水平井具有油层内穿行距离长、泄油面积大、单井产量高等优点,然而水平井轨迹控制却存在诸多难点,水平段轨迹精确控制就是其中之一。根据水平井水平段钻进的实际条件及现场的施工工况,总结出了水平段轨迹控制技术中的关键问题,分析了产生这些问题的原因,提出了相应的预防及解决的技术措施,期望对现场施工人员及科研工作者有所帮助。

Horizontal well has the advantages of long distance in oil,large drainage area,the large production of single well etc.However,horizontal well trajectory control has a lot of difficulty,horizontal section trajectory precision control is one of them.According to the drilling actual conditions and construction conditions of horizontal section in horizontal well,a level key issues is summed up in the trajectory control technology,analyzed the causes of these problems,put forward the corresponding prevention and solution measures.Hope these can help site construction personnel and scientific research workers.
