Description

technical field [0001] The invention relates to the technical field of seismic wave receiving devices, in particular to a three-segment plug-in double detector for easy maintenance. Background technique [0002] A geophone is a seismic wave receiving device used in petroleum seismic exploration. It is divided into land geophones and water geophones. Due to the different working principles of the two geophones, the properties of the received seismic waves are different. At present, in order to preserve the effective waves to the greatest extent and filter out the interference wave components that affect data interpretation, thereby improving the accuracy of seismic data interpretation and providing high-quality well positions for oil exploration, the hydrophone and land geophone are combined to form a dual geophone. Detector. [0003] In order to improve the airtightness of the product, the dual detector geophones currently on the market, the water inspection part, the land...
