[0053] In order to better illustrate the technical effects of the present invention, the following specific embodiments are provided to illustrate the above technical process:

[0054] Embodiment 1: A simple drilling mouse hole device is composed of two parts, namely a mouse hole body 1 and a hole opening support 2.

[0055] 1. Mouse hole body 1

[0056] Its main function is to accommodate the drill tool 3 (drill collar, kelly). It can be processed from the common casing on the well site. Its diameter should be larger than the diameter of the largest drill tool 3, and its length should be longer than the length of the longest drill tool 3 on the well site. The bottom should be welded and sealed tightly to prevent dirt and other sundries from entering and blocking the water holes of the drill tool 3. The top of the hole body penetrates through the drill floor 4 and the bottom goes deep into the ground.

[0057] 2. Hole opening support 2

[0058] The function of the hole opening support 2 is to hold the drill tool 3 for convenient use at any time. Since the drill tools 3 have different lengths and thicknesses, some drill tools 3 (drill pipes 31) have couplings (the protruding parts at both ends), and some drill tools 3 do not have couplings (the whole is of the same thickness). If the drill tool 3 is directly placed into the hole, the long drill tool 3 protruding from the ground too much will hinder the construction, and the short drill tool 3 placed too deep into the mouse hole body 1 is not convenient to extract. The hole opening support 2 is to fix drill tools 3 of various lengths on the mouse hole opening for convenient placement and extraction.

[0059] Two types of baffles are machined on the hole opening support 2. The side baffle 25 mainly blocks the top of the drill tool 3 from obliquely exiting the hole opening, while the flat baffle 23 mainly holds the vertical shaft, drill collar and other drill tools 3 without couplings. The drill pipe 31 with a coupling can lower the flat baffle 23 and directly latch it onto the hole opening support 2.

[0060] The usage process of the present utility model includes the following steps:

[0061] First step: After the drilling rig is placed in place, several hole openings (also called mouse holes) will be punched near the wellhead according to actual needs. After the mouse holes are punched, the processed casing of the mouse hole body 1 is placed in the mouse hole, and the hole opening support 2 is installed at the hole opening of the mouse hole body 1.

[0062] Second step: During the drilling process, after a drill pipe 31 is drilled, the vertical shaft (with a swivel) is removed, and then another drill pipe 31 is added to continue the drilling process, which is called adding a joint. Since the vertical shaft is relatively long (generally about 11 meters for the vertical shaft of ZJ40), it is neither convenient nor safe to hang it on the derrick. At this time, the vertical shaft can be temporarily placed in the mouse hole body 1 (similar to placing chopsticks in a chopstick holder), and after adding the drill pipe 31, the vertical shaft can be installed on the drill pipe 31 to continue drilling.

[0063] Third step: During the drilling process, the subsequent drill pipes 31 to be used can be lifted and placed in more mouse hole bodies 1 and placed firmly according to the types of drill tools 3.

[0064] As described above, only the specific implementation manners of the present utility model are provided, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
