Method for improving the spatial sampling of vertical movement of the fields of seismic waves on the free surface of the earth by the use of sensors of horizontal rotational movement and vertical movement

摘要

Method for improving the spatial sampling of vertical movement of the fields of seismic waves on the free surface of the earth for sensor use horizontal rotational movement and vertical movement. This method proposes the spatial sampling of a field of seismic waves on the free surface of the earth the physical layout of the sensors.The sensors are vertical and particles on the surface of the earth and a horizontal component of the earth's surface. The conditions of tension and fields of waves on the free surface of the earth known to allow the sensor element the rotational movement to the horizontal cross-section of the gradient field of waves of vertical movement of the particles.These data of horizontal gradient and vertical movement of the particles are used in the sampling of an orderly and inclination to achieve improved spatial sampling of the field transverse waves of vertical movement of the particles. The method has a wide range of applications in seismic surveys in the exploration and production of oil and gas.
