The invention discloses a rock sample extraction device and method for a logging tool. The device comprises an expending device, a rock sample grabbing device, a layout device, a rock sample detection device, a shell and a short section shell; the shell is installed inside the short section shell; the shell is provided with three branches which intersect at one place, the layout device is arranged inside the first branch, the expending device is installed on the layout device, the rock sample grabbing device is arranged inside the second branch, and the rock sample detection device is arranged on the third branch. Accordingly, detection is conducted by drilling rock samples from the interior of the wall of a well, and then the influence of drilling fluid disturbance on a test result is overcome; the rock sample grabbing device adopts slant design, and drilling cuttings are more likely to enter a rock sample detection chamber; the rock sample detection chamber also adopts the slant design, a detection window is located at the lowest portion of the rock sample detection chamber, and drilling cutting aggregation is convenient.
Description
technical field [0001] The invention belongs to the field of well logging, and is applied in the exploration and mining of coal, nonferrous metals and other mineral deposits, and in particular relates to a rock sample extraction device and a rock sample extraction method of a well logging tool. Background technique [0002] Well logging refers to the method of using special instruments and equipment to measure geophysical parameters along the wellbore, and to study mineral deposits and related engineering problems. Well logging is one of the important means to discover and evaluate underground resources. [0003] Although people can understand the relevant parameters of mineral deposits through well logging, many interference factors in well logging have always puzzled the relevant workers in this field. For example, in nuclear logging (especially in X-ray fluorescence logging), the drilling fluid will absorb the primary X-rays generated by the excitation source and the cha...
