Abstract

The present invention provides a wireless probe used for near-surface multi-parameter lithology detection. The wireless probe comprises sensors, a signal processing circuit and a computer control system which are connected orderly from front to back. The sensors comprise a three-parameter pore pressure sensor and a natural gamma sensor, the three-parameter pore pressure sensor is located in front of the natural gamma sensor, and the front end of the three-parameter pore pressure sensor is designed into a sharp cone shape. The wireless probe also comprises a pressure bearing shell, and the natural gamma sensor, the signal processing circuit and the computer control system which are connected orderly are arranged inside the pressure bearing shell simultaneously. The front end of the pressure bearing shell is in sealing connection with the back end of the three-parameter pore pressure sensor, a battery is also arranged inside the pressure bearing shell, and the sensors, the signal processing circuit and the computer control system are all connected with the battery. The wireless probe used for the near-surface multi-parameter lithology detection solves the problems that a detection device in the prior art is not high in automation degree and is not convenient to operate.

Description

technical field [0001] The invention relates to a surface lithology detection tool, in particular to a wireless probe for multi-parameter lithology detection near the surface. Background technique [0002] At present, in petroleum seismic exploration, there are mainly two methods for near-surface lithology detection: lithology coring and static detection. The basic method of static detection is to measure and record the formation information that the probe passes through during the process of pressing the probe rod through the method of cable connection. There are certain limitations in certain situations. For example, in areas with high water content, the disturbance of the coring machine makes the coring results unreliable; on the other hand, the high water content makes the result of dividing lithology based on stress difference far from the real situation. [0003] At the same time, the detection device used in the existing cable detection method has the disadvantages ...
