Abstract
The present invention discloses a rock sample extraction device, which comprises a downhole plate and a plurality of sampling components uniformly arranged on the downhole plate, wherein the sampling components are used for sampling rock samples in well areas with different depths, and each sampling component is used for sampling at the upper and lower ends of the same well area; each sampling component comprises anisotropic extraction cylinders arranged on the downhole plate and a power member arranged between the anisotropic extraction cylinders, and the power member drives the anisotropic extraction cylinders to perform telescopic movement in opposite directions, so that the anisotropic extraction cylinders can perform sampling operation when extending outwards.
