封隔器卡瓦损伤套管的模拟试验研究

摘要

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.%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。
