一种化学驱分注井新型电动测调压力调节装置
摘要：
本发明属于油田采油工程三采采油领域，是一种化学驱分注井用新型电动测调压力调节装置。它是针对重复投捞，测试劳动强度较大、工作效率较低等问题而设计的，它由调节杆1、弹簧2、“O”型密封圈3、滑动外套4、主体外套5、堵头6、调节元件7、挡杆8、防脱底堵9及下接头10组成；其中将调节杆1通过螺纹的方式与滑动外套4连接，挡杆8从调节元件7的中心孔穿过，本发明主要应用在化学驱分注井的测调中，具有结构简单、重量轻、使用方便、可降低施工强度、测调效率高等优点。
摘要（英）：

The invention belongs to the field of triple oil recovery in oil production engineering in oil fields, discloses a novel electric pressure measuring and regulating device for a chemical flooding injection well, and aims to solve the problems of repeated recovery, high testing labor intensity, low working efficiency and the like. The novel electric pressure measuring and regulating device consists of a regulating rod 1, a spring 2, an O-shaped sealing ring 3, a sliding outer sleeve 4, a main body outer sleeve 5, a plug 6, a regulating element 7, a blocking rod 8, an anti-drop bottom plug 9 and a lower joint 10, wherein the regulating rod 1 is connected with the sliding outer sleeve 4 in a thread mode; and the blocking rod 8 penetrates through the central hole of the regulating element 7. The novel electric pressure measuring and regulating device is mainly applied to measuring and regulating the chemical flooding injection well, and has the advantages of reducing the construction strength, along with simple structure, light weight, convenience in use, high measuring and regulating efficiency and the like.
