Problems solved by technology

[0003] At present, the rope core drilling method is often used for geological data collection. In the process of geological data collection, it is necessary to put the experimental detection instrument into the detection hole at a certain depth (such as 1500 meters to 2000 meters) for several days. Uninterrupted detection, to obtain relevant experimental data, the exploration hole stored by the experimental instrument is generally smaller than the outer diameter of the exploration hole of the conventional wireline core drilling tool, so several sets of drilling tools are often used in the operation, thus, virtually increasing the drilling time The transportation difficulty of the tool increases the input of manpower and material resources, and increases the cost of geological data collection

Embodiment 1

[0077] A drilling tool for geological data acquisition, comprising an outer pipe assembly 100, a first inner pipe assembly 200 and a second inner pipe assembly 300, the second inner pipe assembly 300 and the first inner pipe assembly 200 can be mutually Replacement connections are made in the outer tube assembly 100 . figure 1 It is a schematic diagram of the assembly of the outer tube assembly and the first inner tube assembly of the geological data acquisition drilling tool described in this application.

[0078] The outer tube assembly 100 includes a bullet stop 2, a bullet chamber 5, a seat ring 7, an outer tube 23 and a lower drill bit 22. The bullet stop 2 is arranged on the upper end of the outer tube assembly 100, and its lower part is sequentially arranged There is an ejection chamber 5, a seat ring 7, an outer pipe 23 and a lower drill bit 22, and the adjacent parts are connected by taper threads; the ejection chamber 5 is set as one section or two continuous section...

Embodiment 2

[0108] Based on the drilling tool described in Embodiment 1, the application also discloses a method for using the geological data acquisition drilling tool, its flow chart, as Figure 10 As shown, it specifically includes the following steps:

[0109] S1, assemble the first inner pipe assembly 200 and arrange it inside the outer pipe assembly 100 to form the first drilling tool, start the first drilling tool to drill the first exploration hole 27 with a predetermined depth, and use the overshot to move the first drilling tool Tool and core lifting;

[0110] Specifically, first assemble the outer pipe assembly 100 and the first inner pipe assembly 200 respectively, install the first inner pipe assembly 200 inside the outer pipe assembly 100 to form the first drilling tool; start the drilling tool to construct the first exploration hole 27, such as Figure 11 As shown, after the construction is completed, use the overshot to lift the first drilling tool and the core.

Abstract

The invention discloses a geological data acquiring drill and a using method thereof. The geological data acquiring drill comprises an outer pipe assembly, a first inner pipe assembly and a second inner pipe assembly, the first inner pipe assembly comprises a first fishing spearhead, a first recycling pipe, first bouncing clamping tongs, a first bouncing clamping frame, a first hanging ring, a first inner pipe, a first clamping spring and a first clamping spring base; a water pressure adjusting device is arranged at the lower portion corresponding to the first bouncing clamping frame to adaptto hole drilling work under different geological conditions; the second inner pipe assembly is arranged inside the outer pipe assembly and is provided with three sets of second elastic clamping sheets, the second inner pipe assembly rotates along with the outer pipe assembly, and a lower portion connecting head above the second inner pipe assembly cooperates with the outer pipe to guarantee the precision of hole drilling. By acquiring data through the geological data acquiring drill, through only one outer pipe assembly and two inner pipe assemblies, the number of drills is reduced, the difficulty of drill transportation is lowered, the investment of labor and financial resources is reduced, the construction efficiency is improved, and the data acquiring cost is lowered.

Description

technical field [0001] The invention relates to a drilling tool for geological data acquisition and a using method thereof. Background technique [0002] Wireline core drilling is an advanced drilling method that can directly obtain core without lifting the drill. Compared with ordinary drilling methods, it has the advantages of good geological effect, high production efficiency and low drilling cost; at the same time, it is widely used because of its simple structure, complete performance, durability and convenient maintenance. [0003] At present, the rope core drilling method is often used for geological data collection. In the process of geological data collection, it is necessary to put the experimental detection instrument into the detection hole at a certain depth (such as 1500 meters to 2000 meters) for several days. Uninterrupted detection, to obtain relevant experimental data, the exploration hole stored by the experimental instrument is generally smaller than the...
