Description
Technical Field
The utility model belongs to the technical field of oil drilling engineering, specifically a well drilling rat hole drilling rod card solid device.
Background
At present, in the construction of a drilling tool for petroleum drilling or well completion and throwing, because the length of a drill rod is different from the length (height) of the drill rod placed in a rat hole, generally, when a single drill rod is drilled and drilled, the single drill rod is placed in the rat hole, then the single drill rod is exposed out of the height of a coupling at the top end of the rat hole, a square drill rod is connected with the single drill rod in a buckling mode, a hydraulic tong is used for tightening, and the single drill rod is lifted away from the rat hole. However, in the process of drilling or well completion and throwing the drilling tool, the drilling tool is detached from the wellhead and then placed in the rat hole, the upper end of the drill rod body is tied with a hoisting belt, the rat hole is lifted by a pneumatic winch, and the drill rod is thrown on the ground. Because the length of a single drill rod is different from that of the drill rod placed in the rat hole after the single drill rod is placed in the rat hole, the length of the single drill rod is smaller than the height of the drill rod placed in the rat hole, the single drill rod is suspended on the rat hole, and an elevator for suspending the single drill rod cannot be opened. The original technology and method are that a section of metal cylinder which is approximately consistent with the inner diameter of the rat hole and has a certain height is placed in the rat hole to make up the difference between the length of the drill rod and the length (height) of the drill rod placed in the rat hole, so that the elevator for hanging a single drill rod is higher than the top end of the rat hole by a certain height, a certain distance gap is formed between the elevator and the top end of the rat hole, the elevator for hanging the drill rod is placed to a proper position, the single drill rod falls down on the cylinder in the rat hole, and the elevator is opened.
The metal cylinder is placed in the rat hole, a steel wire rope is connected to the metal cylinder, the metal cylinder is placed at the bottom in the rat hole, the steel wire rope is fixed at a certain position on the surface of a drilling platform, the metal cylinder is extruded in the rat hole due to the fact that the weight of a single drill rod in the rat hole is pressed down and mud in the single drill rod, or the connected steel wire rope is extruded and broken by the single drill rod, the metal cylinder is difficult to take out after the single drill rod is thrown, and the metal cylinder is often taken out by adopting a gas cutting method. Because the metal cylinder who places has certain approximate height, and every length of drilling rod is different, and the height that single drilling rod exposes can't be adjusted to single drilling rod short-term, leads to sometimes that the elevator can't open. The height of a single drill pipe in the mousehole cannot be adjusted so as to adapt to the problem that the elevator is opened by all the drill pipes. Thus, the prior art cannot solve the above problems well.
