Problems solved by technology

However, the efficiency of threaded connection is low, and frequent disassembly and assembly for a long time will cause certain damage to the thread, which is prone to random buckling and thread loosening, leading to tripping; Under the interaction of bending load and bending load, slipping is easy to occur; secondly, if the thread material is stainless steel, the thread surface will be deformed or damaged during the operation of making and unloading, and it is extremely easy to cause sticking and burning, resulting in inability to disassemble, etc.

Embodiment 1

[0026] The safe and quick connection method of Embodiment 1 of the present invention is applied to a weighted rod, wherein the weighted rod is used to provide the weight required for operation, so that the tool string can fall against the pressure acting on its section and the resistance of the packing box; Rods are the most common type and are manufactured from solid round steel.

[0027] The common weighted rod is integrally formed with the male and female joints and the weighted rod; the two ends of the common weighted rod are respectively provided with male and female joints to ensure the safe and reliable connection between the weighted rod and the tool string. The combination of the slider and the spring is movably inserted into the pin along the radial direction of the slider, and then the pin and the slider are locked and fixed by screws.

[0028] The ordinary weighted rod in Example 1 of the present invention adopts the above-mentioned safe and quick connection method...

Embodiment 2

[0030] The safe and fast connection method of Embodiment 2 of the present invention is applied to chain jars; among them, many steel wires and wire ropes are used for downhole tool strings, and it is often necessary to cut off pins during the fishing process of downhole devices, or Very strong strength is needed when salvaging the downhole device, and it is far from enough to only rely on the pulling force of steel wire or steel wire rope, and it can only be completed by the shock force of the jar. The chain jar is a kind of jar, which is also called a mechanical jar. It uses the instantaneous gravity of the connecting rod to transmit the effective jarring force through the lifting and lowering of the steel wire on the ground. The design of its main and auxiliary chains is based on a Telescopic opening chain effect; the chain jar has a simple structure and can shock up and down, and is the most commonly used jar.

[0031]The main chain of the chain jar is integrally formed wit...

Abstract

The invention relates to a safe fast connecting mode and a safe fast connector. The safe fast connecting mode is specifically as follows: respectively integrally forming male and female connectors with respectively corresponding products and assembling and connecting the male and female connectors in the connecting mode of rotating and matching a clamping block and a clamping slot. The safe fast connector comprises a male connector, a female connector, a sliding block, a pin and a fastening bolt, wherein the male connector comprises a base part and a male connector joint; the clamping block is arranged on the male connector joint; a male connector assembling hole is formed in the female connector; a sliding block storing hole is formed in the tail end of the male connector assembling hole; a spring storing cavity is formed in the tail end of the sliding block storing hole; the clamping slot is formed in an inner hole wall of the male connector assembling hole; a spring is arranged at one end of the sliding block; the male connector joint is connected with the other end of the sliding block; a pin hole matched with the pin is also formed in the sliding block. The connecting mode provided by the invention has the advantages of smart and reasonable design, simple detaching, convenience, high efficiency and capability of effectively avoiding various failure modes of thread connection. The connector provided by the invention has the advantages of reasonable design, fast and convenient in detaching, safe and reliable connection and long service life.

Description

technical field [0001] The invention relates to a quick connection technology between a steel wire and a cable operation tool during well completion downhole testing, in particular to a safe quick connection method and a safe quick joint. Background technique [0002] At present, in the process of well completion and downhole testing, the commonly used connection method between the steel wire and the cable operation tool is threaded connection. Because the thread has the advantages of various forms, easy assembly and detachability, it is widely used in the field of machinery manufacturing. . However, the efficiency of threaded connection is low, and frequent disassembly and assembly for a long time will cause certain damage to the thread, which is prone to random buckling and thread loosening, resulting in tripping; Under the interaction of bending load and bending load, slipping is easy to occur; secondly, if the thread material is stainless steel, the thread surface will ...
