THREE-COMPONENT WELL SEISMOMETER

机译:三分量测井仪

摘要

FIELD: three-component seismic measurements in wells by polarized method. SUBSTANCE: three-component seismometer ensures adequate conditions for linkage of each of its transducers with medium. Seismometer has body suspended with the aid of cable and provided with three sealed containers secured to body in one plane through every 120 deg with the aid of links. Containers accommodate seismotransducers of seismometer components. Mounted on body is power spring resting against slide connected by ties with containers at centers of their mass. Spring force spreads containers along links in radial direction. Suspended from slide with the use of flexible cable is load provided with means intended for securing it on well wall. Weight of load exceeds spring force. Loosening of cable with secured load results in pressing each of three containers to wall of well. Additional equalizing of conditions for linkage of seismometer components with medium is achieved by their grouping. EFFECT: improved accuracy in measurement of polarization and dynamic characteristics of seismic waves. 1 dwg
