The utility model relates to a fixed cement vibration device for a geological drilling completion casing. After the open hole completion is drilled, the vibration device is connected in series at the bottom of the casing string. In the process of cementing, the cement slurry is injected into the casing to replace the drilling fluid, because the first step of radial water hammer vibration and diffraction of the diffraction integrator are generated by the swirling impact of the cement slurry of the hydrocyclone, which drives the eccentric impeller rotator to rotate Before and after the sub rotation, the pressure pulse is generated in the second step longitudinal force, which flows through the second step diffraction integrator to accelerate the cement slurry. Through the venturi tube injection and absorption effect, periodic pressure changes are formed in different flow cross-section areas. Through the jet flow device and rectifier, the third step vibration force is generated. The superposition of the three steps fluid vibration continuously drives the casing string to vibrate irregularly from the bottom to the top, making the cement slurry In order to achieve the purpose of cement dense cementation between the open hole well wall and the annular space of the casing, it is necessary to continuously vibrate and compact the space between the open hole well wall and the annular space of the casing, eliminate the static shear force of the cement slurry, improve the coupling between the cement slurry and the casing and the well wall.

一种地质钻探完井套管固定水泥振动装置
本技术涉及一种地质钻探完井套管固定水泥振动装置,尤其是针对地质钻探完井裸眼井壁与套管环型空间固定水泥完井振动井下工具装置。
技术介绍
我国每年地质钻探近2万口各类油、气、液等井,钻探裸眼完成后,将套管固定在裸眼井壁,使套管形成从井底到地面成为唯一通道。主要是通过地面井口从套管内将水泥浆循环到裸眼井壁与套管环型空间,将套管用水泥浆固定在裸眼完钻的井壁上,在水泥浆循环过程中,无法将产生的水泥浆气泡彻底消除,固井水泥凝固后,容易在裸眼井壁与套管环型空间,形成气泡夹层,影响固井质量。对采油、采气、采液等后续井下施工生产过程中,偶然有油、气、水及伴生有害液体和气体,通过井壁与套管环型空间的气泡夹层上行到地面。不仅影响采油、采气、采液开发生产和后续封堵井下作业施工增加费用等问题,还会影响到环境污染、易燃易爆等安全问题。
