Inflatable active packer
The inflatable active packer comprises a cylindrical inner steel pile, the inner steel pile is coaxially sleeved with a sleeve, the inner diameter of the sleeve is larger than the outer diameter of the inner steel pile, the length of the sleeve is not larger than that of the inner steel pile, a guide block is fixedly connected to the position, close to the end of the sleeve, of the inner wall of the sleeve, the inner wall of the sleeve abuts against a high-strength clamping layer, and a rubber capsule is fixedly connected to the middle of the high-strength clamping layer. The two ends of the high-strength clamping layer are fixedly connected with the sleeve through a pressing device, an inflation air nozzle mounting hole is formed in the middle of the high-strength clamping layer, the sleeve is provided with a through hole which is coaxial with the inflation air nozzle mounting hole and has the same diameter with the inflation air nozzle mounting hole, and an inflation air nozzle is clamped in the inflation air nozzle mounting hole and penetrates through the sleeve and the high-strength clamping layer to be inserted into the rubber capsule. The inflatable active packer is ingenious in structural design, simple in working principle and easy to operate, can provide supporting force larger than the gravity of cement paste, improves the sealing performance and is more beneficial to application in deep sea.
本发明公开了气胀式主动封隔器，包括呈筒状的内钢桩，内钢桩同轴套接有套筒，套筒内径大于内钢桩外径，套筒长度不大于内钢桩长度，套筒内壁且靠近套筒端部固接有导向块，套筒内壁抵接有高强卡位层，高强卡位层中部固接有橡胶胶囊，高强卡位层两端通过压紧装置和套筒固接，高强卡位层中部开有充气气嘴安装孔，套筒开有与充气气嘴安装孔同轴且直径相同的通孔，充气气嘴安装孔内卡接有充气气嘴，充气气嘴贯穿套筒和高强卡位层插入橡胶胶囊内部。本发明结构设计巧妙，工作原理简单，易操作，该气胀式主动封隔器可提供大于水泥浆自身重力的支撑力，提高密封性能，更有利于在深海进行应用。
