High-temperature direct-pushing lithologic density instrument
The utility model belongs to the technical field of logging instruments, and discloses a high-temperature direct-pushing lithologic density instrument which comprises a main body and a density probe, a containing groove matched with the density probe is formed in the main body, and a plate-shaped spring is further arranged in the containing groove. The device is characterized by also comprising a connecting arm reed and a pressing block, the connecting arm reed is S-shaped, and one end of the connecting arm reed is provided with a tooth groove and a long-strip-shaped hole. The pressing block is provided with a tooth groove and a bolt hole. According to the scheme, the problems that the attaching state of the probe and the well wall is not ideal and the well logging effect is poor due to the fact that a single supporting reed is insufficient in supporting force are effectively solved. According to the scheme, the connecting arm reed is of an S-shaped structure, the single side of the connecting arm reed is open, the connecting arm reed is fully attached to the connecting arm, and the supporting force is evenly released.
