[0001] This invention relates to the field of integrated logging technology for horizontal boreholes, and more specifically, to a pushing device suitable for cabled logging equipment in horizontal boreholes. The invention also relates to a pushing method for this pushing device suitable for cabled logging equipment in horizontal boreholes. Background Technology

[0002] For some challenging areas in geological exploration, such as areas where conventional surface shaft drilling and geophysical exploration cannot be carried out, or tunnel areas with relatively complex geological conditions, where advanced geological prediction for tunnels cannot meet the requirements for construction safety in terms of detection range and data accuracy, horizontal directional drilling combined with in-hole integrated logging technology can intuitively and accurately understand the geological conditions of rock strata, and precisely delineate the lithological changes and fracture zone distribution of the surrounding rock, which can assist geologists in completing precise geological exploration in challenging areas.

[0003] Due to the special construction conditions of horizontal drilling, conventional cabled logging equipment is difficult to safely and effectively push to the bottom of the hole to complete the comprehensive logging work.

[0004] Therefore, it is necessary to develop a device and method for pushing cable logging equipment to the bottom of a horizontal borehole, so that cable logging equipment can effectively complete comprehensive logging work in a horizontal borehole. Summary of the Invention

[0005] The primary objective of this invention is to overcome the shortcomings of the aforementioned background technology and to provide a pushing device suitable for cabled equipment in horizontal drilling.

[0006] A second objective of the present invention is to provide a pushing method for this pushing device suitable for cabled equipment in horizontal drilling.

[0007] To achieve the aforementioned first objective, the technical solution of the present invention is as follows: a pushing device suitable for cabled equipment for horizontal drilling, characterized in that it includes a pushing device base, a pushing device upper bracket located above the middle part of the pushing device base, a first connecting rope, and a second connecting rope.

[0008] The base of the pushing device has a reserved channel; one end of the first connecting rope is connected to the left end of the card seat on the pushing device, and the other end enters the reserved channel from the top of the left end of the pushing device base, extends out of the reserved channel from the middle of the pushing device base, and is connected to the spearhead.

[0009] A fixed pulley is provided inside the right end of the card holder of the pushing device, and the second connecting rope fixed pulley is matched accordingly.

[0010] The base of the pushing device is provided with a first support, and the left end of the card seat of the pushing device is provided with a second support. One end of the first rotating shaft is hinged to the first support and the other end is hinged to the second support.

[0011] In the above technical solution, a limiting hole is provided at the right end of the base of the pushing device, a limiting ring is provided in the middle of the spearhead, and the part between the right end of the spearhead and the limiting ring is located in the limiting hole.

[0012] In the above technical solution, a third support is provided on the base of the pushing device, the third support is located to the right of the first support, a fourth support is provided in the middle of the card seat on the pushing device, one end of the second rotating shaft is hinged to the third support, and the other end is hinged to the fourth support.

[0013] In the above technical solution, a first limiting block is provided on the top right side of the first support, and a second limiting block is provided on the top right side of the third support.

[0014] To achieve the second objective mentioned above, the technical solution of the present invention is as follows: a method for pushing a pushing device suitable for horizontal drilling cable-stayed equipment, characterized by comprising the following steps:

[0015] Step 1: The base of the pushing device and the card seat on the pushing device are tightly attached. The A end of the second connecting rope is left outside the opening of the horizontal borehole. The second connecting rope left outside the opening of the horizontal borehole is long enough. The B end of the second connecting rope is fixed to the front end of the drill rod of the drilling machine. The drill rod of the drilling machine contacts the left side of the base of the pushing device. The drill rod of the drilling machine slowly pushes the base of the pushing device to the bottom of the horizontal borehole.

[0016] Step 2: Pull the second connecting rope A end that is left outside the opening of the horizontal borehole, causing the upper bracket of the pushing device to rotate around the first and second rotating axes. The base of the pushing device and the upper bracket of the pushing device separate. Both the base of the pushing device and the upper bracket of the pushing device are tightly attached to the rock wall of the horizontal borehole. The base of the pushing device and the upper bracket of the pushing device are locked at the bottom of the horizontal borehole.

[0017] Step 3: Slowly move the drill rod out of the drilling rig. The base of the pushing device and the chuck on the pushing device remain at the bottom of the horizontal borehole. The B end of the second connecting rope moves out of the horizontal borehole with the drill rod and separates the B end of the second connecting rope from the front end of the drill rod. Since the second connecting rope left at the opening of the horizontal borehole is long enough, the A end of the second connecting rope is outside the opening of the horizontal borehole.

[0018] Step 4: Connect the cable logging equipment to end B of the second connecting rope, pull end A of the second connecting rope, and use the fixed pulley to drive the cable logging equipment into the horizontal borehole, thus completing the pushing of the cable logging equipment. The cable logging equipment completes the logging work in the horizontal borehole.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1) The invention is pushed to the bottom of the horizontal borehole using the drill rod of the drilling rig. The base of the pushing device and the card seat on the pushing device are snapped at the bottom of the borehole. The fixed pulley and the second connecting rope are used to effectively push the cable logging equipment in the horizontal borehole, which solves the problem that the cable logging equipment is difficult to push safely and effectively in the horizontal borehole. It can assist the cable logging equipment in completing the comprehensive logging work in the horizontal borehole.

[0021] 2) This invention has a simple structure, is easy to use, and has low cost. It plays an important role in promoting and has practical value in the comprehensive logging of horizontal boreholes with cable logging equipment. Attached Figure Description

Detailed Implementation

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but these descriptions are not intended to limit the invention and are merely illustrative. The advantages of the present invention will become clearer and easier to understand through this description.

[0026] Referring to the accompanying drawings, a pushing device suitable for cabled equipment in horizontal drilling is characterized by comprising a pushing device base 1, a pushing device upper bracket 2 located above the middle part of the pushing device base 1, a first connecting rope 3, and a second connecting rope 4.

[0027] The base 1 of the pushing device has a reserved channel 11; one end of the first connecting rope 3 is connected to the left end of the card seat 2 on the pushing device, and the other end enters the reserved channel 11 from the top of the left end of the pushing device base 1, extends out of the reserved channel 11 from the middle of the pushing device base 1, and is connected to the spearhead 12.

[0028] A fixed pulley 21 is provided inside the right end of the upper card seat 2 of the pushing device, and the second connecting rope 4 is matched with the fixed pulley 21.

[0029] The base 1 of the pushing device is provided with a first support 13, and the left end of the card seat 2 of the pushing device is provided with a second support 22. One end of the first rotating shaft 31 is hinged to the first support 13 and the other end is hinged to the second support 22.

[0030] The base 1 of the pushing device is provided with a limiting hole 14 at the right end, and the spearhead 12 is provided with a limiting ring 121 in the middle. The part between the right end of the spearhead 12 and the limiting ring 121 is located in the limiting hole 14.

[0031] The base 1 of the pushing device is provided with a third support 15, which is located to the right of the first support 13. The middle of the card seat 2 of the pushing device is provided with a fourth support 23. One end of the second rotating shaft 32 is hinged to the third support 15 and the other end is hinged to the fourth support 23.

[0032] A first limiting block 131 is provided on the top right side of the first support 13, and a second limiting block 151 is provided on the top right side of the third support 15.

[0033] Both the first connecting rope 3 and the second connecting rope 4 are made of steel wire or high-strength rope.

[0034] A method for pushing a pushing device suitable for cabled equipment in horizontal drilling includes the following steps:

[0035] Step 1: The base 1 of the pushing device and the upper bracket 2 of the pushing device are tightly attached. The A end of the second connecting rope 4 is left outside the opening of the horizontal borehole. The second connecting rope 4 left outside the opening of the horizontal borehole is long enough. The B end of the second connecting rope 4 is fixed to the front end of the drill rod of the drilling machine. The drill rod of the drilling machine contacts the left side of the base 1 of the pushing device. The drill rod of the drilling machine slowly pushes the base 1 of the pushing device to the bottom of the horizontal borehole.

[0036] Step 2: Pull the end of the second connecting rope 4A that is left outside the opening of the horizontal borehole, causing the upper bracket 2 of the pushing device to rotate around the first rotating shaft 31 and the second rotating shaft (32). The base 1 of the pushing device and the upper bracket 2 of the pushing device separate. The base (1) of the pushing device and the upper bracket 2 of the pushing device are tightly attached to the rock wall of the horizontal borehole. The base 1 of the pushing device and the upper bracket 2 of the pushing device are locked at the bottom of the horizontal borehole.

[0037] Step 3: Slowly move the drill rod out of the drilling rig. The base 1 of the pushing device and the chuck 2 of the pushing device remain at the bottom of the horizontal borehole. The B end of the second connecting rope 4 moves out of the horizontal borehole with the drill rod and separates the B end of the second connecting rope 4 from the front end of the drill rod. Since the second connecting rope left at the opening of the horizontal borehole is long enough, the A end of the second connecting rope 4 is outside the opening of the horizontal borehole.

[0038] Step 4: Connect the cable logging equipment to end B of the second connecting rope, pull end A of the second connecting rope, and use the fixed pulley 21 to make end B of the second connecting rope drive the cable logging equipment into the horizontal borehole, thus completing the pushing of the cable logging equipment. The cable logging equipment completes the logging work in the horizontal borehole.

[0039] Step 4: Connect the cable logging equipment to end B of the second connecting rope 4, pull end A of the second connecting rope 4, and use the fixed pulley 21 to drive the cable logging equipment into the horizontal borehole, thus completing the pushing of the cable logging equipment. The cable logging equipment completes the logging work in the horizontal borehole.

[0040] Step 5: Pull end A of the second connecting rope so that end B of the second connecting rope moves toward the retrieval spearhead 12, and the retrieval device at end B of the second connecting rope locks onto the retrieval spearhead 12.

[0041] Step 6: Pull end A of the second connecting rope, and end B of the second connecting rope will pull the retrieval head 12 to rotate. The retrieval head 12 will pull the left end of the upper bracket 2 of the pushing device through the first connecting rope 3, so that the base 1 of the pushing device and the upper bracket 2 of the pushing device are in close contact. Continue to pull end A of the second connecting rope to retrieve the cable logging equipment, the base 1 of the pushing device, and the upper bracket 2 of the pushing device.

[0042] In practical use, a retrieval device can also be connected to the drill rod of the drilling rig to send the drill rod to the bottom of the hole. The retrieval device locks the retrieval spearhead 12, and the drill rod pulls back the retrieval spearhead 12, so that the base 1 of the pushing device and the upper seat 2 of the pushing device can be used to recover the cable logging equipment, the base 1 of the pushing device and the upper seat 2 of the pushing device.

[0043] All other unspecified parts belong to the prior art.
