Abstract:
Aiming at the problems of low burying efficiency, poor coupling, high inclination and inconvenient portability of traditional geophone burying tools in soft soil layer environments during the layout process of wide-azimuth, widebandwidth and high-density seismic acquisition, this paper develops an integrated tool for soft soil layers. Based on the design concept of functional integration and modularization, the tool integrates a hoe, a hammer and guide cones for different types of geophones into one unit. The materials and structure are optimized according to the application environments and scenarios, achieving lightweight design and easy operation of the tool. Field applications in different work areas of the Sichuan Basin show that after using this tool, the average burying time per geophone is reduced from 72.33 seconds to 57.03 seconds, with the operation efficiency thereby improved by more than 21%. Meanwhile, it effectively enhances the coupling quality of geophone burying, reduces the burying inclination and lowers the labor intensity of operators. This tool provides an efficient, standardized and effective technical equipment for geophone burying in soft soil layers during high-density seismic acquisition, and has significant popularization and application value.
针对“两宽一高”高密度地震采集排列工序,传统检波器埋置工具在软土层埋置环境存在埋置检波器效率低、耦合度较差、倾斜度大和携带不便等问题,本文基于以上问题研发了一款软土层一体化专用工具。研究基于功能集成与模块化设计理念,将锄头、榔头及不同类型检波器的引锥集成为一体,根据使用环境及场景优化材料与结构,实现了工具的轻量化和便携化。在四川盆地不同工区软土层的现场应用表明,使用该工具后,单点检波器平均埋置时间从72.33秒降至57.03秒,作业效率提升逾21%,同时有效提升检波器埋置耦合质量,减少埋置倾斜度并降低操作人员劳动强度。该工具为高密度地震采集中、检波器在软土层的埋置作业,提供了高效、规范、实用的专用技术装备,具有显著推广应用价值。
