随着油气井测试技术的不断发展,在钻井过程中进行中途测试(DST)越来越为人们所重视,成为获取地层流动及流体组份等信息的重要手段之一。试油螺杆泵与常规的DST管柱相配合,可以十分方便地在自喷或非自喷井上进行常规的中途测试及试油作业,具有测试管柱简单、施工方便、测试数据直观可靠等优点。 With the continuous development of oil and gas well test technology, the midway test (DST) in the drilling process is paid more and more attention, which becomes one of the important means to get the information of formation flow and fluid composition. Test oil screw pump and conventional DST column match, you can easily in the spray or non-self-injection wells for routine midway test and test oil operations, with a simple test string, construction convenience, intuitive and reliable test data, etc. .
