中文摘要:南扶273-平253井是大庆油田一口重点实验井，采用全过程欠平衡技术钻进，钻探目的层位是FI5油层。在全过程欠平衡钻井作业过程中，通过井下套管阀开关，保证井底始终处于欠平衡状态，成功地进行了欠平衡钻进、不压井起下钻等作业，有效地保护了储层。介绍了应用于该井的全过程欠平衡技术﹑井眼轨迹控制技术﹑设备选择以及现场出现过的问题和解决方法等。
中文关键词:水平井  欠平衡  钻井  井眼轨迹
 
Application of Whole Process Underbalanced Horizontal Well in Daqing Oil Field
Abstract:Nanfu 273-Ping 253 well is an important experimental well in Daqing oil field, which was drilled by whole process unbalanced technology with the target layer of F15 oil reservoir. Unbalanced state was kept at the bottom of the well by downhole casing shut-off valve in whole process unbalanced drilling operation, the oil reservoir was protected by unbalanced drilling and non-snubbing service. The paper introduced the whole process unbalanced technology, well trajectory control, equipment selection, the difficult problems in field and the countermeasures.
