A skid-mounted depressurizing system includes a main process module, a mechanical control system, a thermodynamic balance system and an intelligent control system. The main process module includes multiple main process pipelines, each of the multiple main process pipelines is provided with a pressure reducing valve set. During depressurization, process medium enters at least one of the multiple main process pipelines, the mechanical control system outputs a torque according to the control instruction of the intelligent control system to control each valve of the multiple main process pipelines to perform an action switch and an opening degree adjustment, the thermodynamic balance system is configured to provide the medium of different properties to the multiple main process pipelines according to the control instruction of the intelligent control system to control temperature, pressure, cleanliness degree and/or sealing degree of the main process module.

The invention discloses an omnidirectional vector seismic data processing method and apparatus, a computer readable storage medium and a device, applied to an omnidirectional vector geophone. Wherein the method comprises: collecting omnidirectional vector seismic data of the omnidirectional vector geophone, and performing a pre-processing operation on the omnidirectional vector seismic data; performing pressure and shear waves separation operation on the omnidirectional vector seismic data after the data is subject to the pre-processing operation, to obtain pressure wave data and shear wave data; sequentially performing space vector calculation, a wave field recovery operation and an imaging operation on the pressure wave data and the shear wave data, and then performing modeling to obtain a pressure wave velocity model and a shear wave velocity model. The invention solves the problem of the existing seismic exploration technology that cannot measure and process divergence data and curl data of seismic wave field, so as to improve construction, lithology, fluid exploration accuracy and reliability and promote seismic exploration to be developed from structural exploration to lithology exploration and fluid exploration.
