Description

Technical Field

[0001] The utility model relates to the technical field of reaming devices, in particular to an expansion-type while-drilling reaming device. Background Art

[0002] As oil and gas drilling and completion develop towards extended reach wells and expansion tube completion, the drilling conditions are becoming more and more complex. Hole expansion while drilling technology is a very effective means to deal with complex conditions such as wellbore shrinkage. By expanding the wellbore diameter, the casing annulus gap is increased, which is beneficial to the insertion of casing and expansion tube, increasing the thickness of cement sheath, and improving the cementing quality of the target layer.

[0003] At present, the most commonly used drilling reamer is an arm-type reamer, that is, the blade is similar to the human arm to expand the turning radius, and the blade is connected to the body by a pin shaft, so it is inconvenient for personnel to adjust the reamer plate. To this end, we propose an expansion drilling reamer. Utility Model Content

[0005] The technical solution adopted by the utility model to solve its technical problems is an expansion type drilling reaming device, comprising a cylinder and a vertical rod, an adjusting mechanism is installed at the rod wall of the vertical rod, and the adjusting mechanism is composed of a horizontal plate, a threaded rod A, a threaded sleeve A, a connecting plate, a threaded rod B, a threaded sleeve B, an reaming plate and a slot body. A group of symmetrical horizontal plates are welded at the rod wall of the vertical rod, a group of symmetrical threaded rods A are plugged and connected at the plate wall of the horizontal plate, a group of the threaded rods A are threadedly connected at the rod wall with a group of symmetrical threaded sleeves A, a group of the threaded rods A are welded at the rod wall with a connecting plate, a reaming plate is installed at the plate wall of the connecting plate, a group of symmetrical threaded rods B are welded at the rod wall of the vertical rod, a slot body is opened at the plate wall of the connecting plate, and the threaded rod B runs through the slot body, and a group of the threaded rods B are threadedly connected at the rod wall with a group of symmetrical threaded sleeves B.

[0006] By adopting the above technical scheme, when adjusting the spacing between the reaming plates, since the adjusting mechanism is installed at the rod wall of the vertical rod, the adjusting mechanism is composed of a horizontal plate, a threaded rod A, a threaded sleeve A, a connecting plate, a threaded rod B, a threaded sleeve B, an reaming plate and a groove body. After a person rotates the connecting plate to make the threaded rod A rotate between the horizontal plates, since the threaded sleeve A is threadedly connected at the rod wall of the threaded rod A, the threaded sleeve A is twisted so that the threaded sleeve A squeezes the horizontal plate to fix the threaded rod A. Since a groove body is provided at the plate wall of the connecting plate, the threaded rod B passes through the groove body. After the person loosens the threaded sleeve B, the threaded rod B moves in the groove body. After the person twists the threaded sleeve B, the threaded sleeve B squeezes the connecting plate to fix the connecting plate. Since the reaming plate is installed at the plate wall of the connecting plate, it is convenient for the person to adjust the spacing between the reaming plates.

[0007] Specifically, it also includes a clamping mechanism, and the clamping mechanism is installed on the cylinder wall of the cylinder.

[0008] By adopting the above technical solution, the cylinder body can be conveniently connected to the outside through the clamping mechanism.

[0009] Specifically, the clamping mechanism is composed of a screw rod, a clamping plate and a tooth groove. A group of symmetrical screw rods are threadedly connected to the cylinder wall of the cylinder body. The other end of the screw rods is connected to a clamping plate through a bearing. The clamping plate has a tooth groove on its plate wall.

[0010] By adopting the above technical scheme, when the cylinder is connected to the outside, since a clamping mechanism is installed on the wall of the cylinder, after the personnel inserts the external rotating shaft into the cylinder, the external rotating shaft is located between the clamping plates. Since a group of symmetrical screw rods are threadedly connected to the wall of the cylinder, the other end of the screw rods is connected to the clamping plates through bearings. Therefore, after the personnel twists the screw rods, the screw rods push the clamping plates to move. Since a tooth groove is provided on the wall of the clamping plates, the rotating shaft is clamped and fixed by the clamping plates, thereby facilitating the connection of the cylinder with the external rotating shaft.

[0011] Specifically, the clamping plate is located on the inner wall of the cylinder.

[0012] By adopting the above technical solution, the clamping plate can be conveniently clamped and fixed to the external rotating shaft.

[0013] Specifically, a vertical rod is welded at the bottom of the cylinder.

[0014] By adopting the above technical solution, it is convenient to fix the vertical rod.
