The invention relates to a coiled tubing tubular column hydraulic breakage device. A plurality of hole channels are formed in the lower end of an upper tubular column, adjacent two lines of hole channels formed in an interlacing mode and a ball is arranged in each hole channel; concave holes are formed in the inner wall of a lower contact, the upper tubular column inserts into the lower contact and each hole channel of the upper tubular column corresponds to each concave hole of the lower contact in a one-to-one mode; the lower end of a chuck is connected with a supporting piston in a threading mode and the chunk and the supporting piston are located in the cavity formed by the upper tubular column and the lower contact; the chuck communicates with the supporting piston by respective center passageway; chuck jaws are arranged on the upper portion of the chuck, a clamping shoulder is formed at the upper end of each chuck jaw correspondingly and chunk jaws are clamped on a boss of the upper tubular column by the clamping shoulder; a piston shoulder of the supporting piston is clamped at the lower end opening of the upper tubular column; sliding grooves are formed in the external wallof the supporting piston and a pit is formed in each sliding groove correspondingly; when the piston shoulder moves to a circular bead of the upper tubular column, the pits of the sliding grooves correspond to hole channels of the upper tubular column in a one-to-one mode. A repeating shaking shock can be borne and is prevented from separating prematurely and the chuck is not out of operation prematurely.

The invention discloses a cutting device for corrugated paper with a fixed cutting distance, convenient adjustment and protection function, which comprises a push plate and a support table, the push plate is slidably installed on the upper part of one end of the support table, and the inside of the push plate is opened with a A card slot is placed, and a moving card slot is opened through the middle of one end of the support table close to the push plate. The middle part of the end is fixedly connected with a connecting plate, an adjustment device is installed under the support platform, a cutting protection device is installed above the adjustment device, and a limiting plate is installed in the adjustment device. The device can quickly cut corrugated paper in the process of use, and the cutting distance of the cut corrugated paper is the same, which ensures the same specification of the cut corrugated paper, and can protect the operator during use, and the use and adjustment are convenient and quick.

The invention discloses a well testing steel wire releasing tool which comprises a salvage head, a mandrel, an outer spring, a transposition pin, an upper torque ring, a rotary nut, an outer cylinder,a lower torque ring, an inner spring and a duckbill. The well testing steel wire releasing tool is connected into a well testing tool string and lowered into a well with all tools simultaneously, when the tool is clamped and cannot be unclamped through other unclamping tools, a well testing steel wire can be gently lifted and lowered up and down, when the number of lifting and lowering times reaches a certain numerical value, downhole tool releasing is achieved, all the tools above the well testing steel wire releasing tool can be safely lifted to the ground, the construction loss is reducedto the largest limit, and well testing steel wire fatigue caused by multiple-time shock can also be avoided.

The invention discloses a TPR shoe surface modification technology. The modification technology comprises the following steps of (1) a TPR shoe surface processing step, in which a TPR specific processing agent is employed to clean the external surface of the shoe and soften the external surface, and the shoe external surface is dried for 10 to 20 minutes, (2) a priming paint spraying step, in which a paint spraying device is employed to spray priming paint to the TPR shoe to form a flat priming paint plane on the external of the TPR shoe, and then the shoe sprayed with the priming paint is dried by 10 to 20 minutes at the temperature of 60 to 70 DEG C, (3) a metal spraying step, in which a spraying device is employed to spray an imitating metal layer on the priming paint, and then the imitating metal layer is dried for 5 to 10 minutes at the temperature of 60 to 70 DEG C, and (4) a spraying device is employed to spray a layer of surface paint on the external surface of the imitating metal layer and then the shoe is dried.
