多臂井径测井仪主要用于测量套管内径变化，提供套管变径、壁厚、套管外径变化、椭圆变形及等效破坏载荷等评价资料。 - Abstract : anchor packer is one of the important downhole tools which areused in oil production and waterflood technical operation , such as layer waterflood , layer fracture or acidation , mechanical water block . after anchor is fixed in the simulated test unit , the invasion depth of the casing can be known with the help of the sensor around the casing wall , and then the failure degree is concluded . this is very important for the anchor packer design and site operation
文摘:在油田开发中封隔器是实施机械采油、分层注水、分层压裂或酸化、机械卡堵水等注采工艺作业的主要井下工具之一，封隔器上的卡瓦是保证工作可靠性的重要元件，把卡瓦安装在模拟试验装置中，通过在套管壁周围分布位移传感器，测得卡瓦锚定后切入套管壁深度，判断卡瓦对套管的损伤程度，这对封隔器的设计和现场使用具有十分重要的意义。 - The new unit adopts hollow sucker rod working with pump and as fluid passage instead of conventional sucker rod , and uses a new hanger to fix the one - piece barrel rod pump on the casing wall , improving the operation stability of the subsurface pump
针对这种情况，大港油田新世纪机械制造有限公司研制成功一种新型无油管采油装置，这种装置以空心抽油杆代替实心抽油杆带泵工作并兼作出油流道，还通过一种新型悬挂器将整筒抽油泵固定在套管壁上，提高了抽油泵的工作稳定性。
