The invention discloses an ultra-deep micro-logging electric spark source wellhead damping lifting device which comprises a frame body, a spring damper and a fixed pulley. The spring shock absorber is longitudinally installed on the frame body, and the fixed pulley is installed at the lower end of the spring shock absorber. The frame body is a tripod, a base is arranged at the lower end of each foot of the tripod, and an air bag damper is installed at the bottom of each base. A top cover is arranged at the top end of the tripod, and an installation center hole used for installing a spring shock absorber is formed in the center of the top cover. According to the invention, the excitation probe can accurately reach the designed depth by using the lifting and self-locking functions of the hand-cranking capstan, explosion shaking is eliminated by using the top cover damping spring and the base damping air bag, and the interference of pseudo seismic waves on useful signals is reduced.
本发明公开了一种超深微测井电火花震源井口减震升降装置,包括架体,还包括弹簧减震器、定滑轮;所述弹簧减震器纵向安装在架体上,所述定滑轮安装在弹簧减震器的下端。所述架体为三脚架,所述三脚架的每个脚的下端为底座,底座底部安装有气囊减震器。所述三脚架顶端为顶盖,所述顶盖中心设置用于安装弹簧减震器的安装中心孔。本发明利用手摇绞盘的升降和自锁功能使激发探头能精确到达设计深度,利用顶盖减震弹簧和底座减震气囊消除爆炸抖动,减少伪地震波对有用信号的干扰。
