Abstract
Description
Technical Field
[0001] This utility model relates to the field of geological surveying technology, specifically to an inclination mapping device. Background Technology
[0002] A formation dip logging tool is an instrument used inside a borehole to determine the strike, dip, and dip angle of rock formations; it is also called a formation attitude instrument and is often used in conjunction with a data analyzer. It consists of two parts: one part measures the dip angle and azimuth of the rock formation relative to the borehole; the other part measures the dip, azimuth, and borehole diameter of the borehole itself. The combined data can be used to determine the attitude of the rock formations. It is an instrument for determining the dip of rock formations relative to the borehole axis. It consists of four sets of electrodes located in the same plane (perpendicular to the borehole axis) at 120° angles to each other. Depending on the specific rock formation, micro-lateral logging curves or other logging curves can be recorded. Based on the interface depth determined from the three or four measured curves, and the borehole diameter data, the dip angle of the rock formation relative to the borehole can be obtained. The measurement principles of electrode azimuth, borehole dip angle, and borehole diameter are similar to those of general well inclination gauges and well diameter gauges.
[0003] Current formation dip logging tools are often used in conjunction with pull ropes. The pull rope is tied to a pull ring to lower the tool into the borehole. The pull ring is fixed to a connecting sleeve, which is usually threaded onto the tool's housing or bolted on. Another example is the mining borehole depth and dip angle measuring device disclosed in application number 202223160447.4. A protractor is fixedly connected to the left side of the clamp, and a connecting rope is fixedly connected to the clamp. A plumb bob is connected to the bottom of the connecting rope. The protractor and plumb bob together can quickly and accurately detect the borehole's dip angle. However, its installation and measurement process is time-consuming and labor-intensive, reducing the assembly efficiency of the formation dip logging tool. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a dip angle mapping device, which aims to improve the current dip angle mapping devices that are often used in conjunction with pull ropes, making the installation and measurement process time-consuming and labor-intensive, thus reducing the assembly efficiency of formation dip angle logging tools.

[0007] The locking mechanism is installed on the fixing sleeve, and the locking mechanism is configured to restrict and fix the fixing sleeve to the plug.
[0008] Preferably, the plug is a combination of a frustum and a column.
[0009] Preferably, a metal braided sleeve is also included, which is fixedly fitted onto the pull rope.
[0010] Preferably, the locking mechanism includes a locking block, a spring, and a guide rod. The locking block is slidably disposed on the fixed sleeve. One end of the guide rod is fixed to the outer wall of the locking block and slides through the fixed sleeve.

[0022] Example 1: A preferred embodiment of this utility model provides an inclination mapping device, including a formation inclination logging tool 110, a plug 120, a fixing sleeve 130, a ring 140, a pull rope 150, and a locking mechanism 170. The lower end of the plug 120 is fixed to the upper surface of the housing of the formation inclination logging tool 110. The fixing sleeve 130 is sleeved on the plug 120. The ring 140 is installed between the fixing sleeve 130 and the pull rope 150. The plug 120 is a combination of a frustum and a column. It also includes a metal braided sleeve 160, which is fixedly sleeved on the pull rope 150. The metal braided sleeve 160 is used to protect the pull rope 150 and effectively prevent the pull rope 150 from being worn out. The formation inclination logging tool 110 is a four-arm formation inclination logging tool.
[0023] Example 2: A preferred embodiment of this utility model provides an inclination surveying device, which differs from the above embodiments only in that:
[0024] The locking mechanism 170 is installed on the fixed sleeve 130. The locking mechanism 170 restricts and fixes the fixed sleeve 130 to the plug 120. The locking mechanism 170 includes a locking block 171, a spring 173, and a guide rod 174. The locking block 171 is slidably disposed on the fixed sleeve 130. One end of the guide rod 174 is fixed to the outer wall of the locking block 171 and slides through the fixed sleeve 130. One end of the spring 173 is fixed to the outer wall of the locking block 171 and the other end of the spring 173 is fixed inside the fixed sleeve 130. The guide rod 174 passes through the spring 173. A through hole 172 is provided on the fixed sleeve 130. Both the guide rod 174 and the locking block 171 are slidably disposed on the through hole 172. One end of the spring 173 is fixed inside the through hole 172.
[0025] Example 3: A preferred embodiment of the present invention provides an inclination surveying device, which differs from the above embodiment only in that it further includes a pull block 175, which is fixed on the other end of the guide rod 174. The pull block 175 facilitates the pulling of the guide rod 174.
[0026] In use, the fixing sleeve 130 is fitted onto the plug 120, and the fixing sleeve 130 is pressed down. The plug 120 compresses the locking block 171, causing the locking block 171 to enter the through hole 172. When the upper end of the plug 120 contacts the inner wall of the fixing sleeve 130, the locking block 171 protrudes out of the through hole 172 under the reaction force of the spring 173, locking the plug 120. This allows the fixing sleeve 130 to be quickly assembled onto the housing of the formation dip logging tool 110. When it is necessary to remove the fixing sleeve 130, the pull block 175 is pulled, causing the locking block 171 to fully enter the through hole 172. Within 72 seconds, the fixing sleeve 130 can be pulled out to separate the fixing sleeve 130 and the plug 120. Then, holding the pull rope 150, the formation dip logging instrument 110 is lowered into the borehole. The formation dip logging instrument 110 can map the dip angle of the rock formation. The metal braided sleeve 160 prevents the pull rope 150 from being worn off, improving the safety of the formation dip logging instrument 110. This rock formation dip mapping device uses the locking mechanism 170 to quickly assemble the fixing sleeve 130 and the plug 120, saving time and effort and improving the assembly efficiency of the formation dip logging instrument 110.
[0027] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
