Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to an upward and downward impact type rebound jam-releasing device. Background Art

[0002] In the geological drilling production process, it is inevitable to encounter unpredictable drilling drill stuck accidents, which require a large investment of manpower and material resources, especially the investment in the process tools for unstuck drilling. The existing general conventional process tools are drilling fluid adjustment unstuck drilling, inverted unstuck drilling, and shock short joint unstuck drilling. When operating, different specifications of drilling tools need to be used in conjunction, and often multiple different models need to be equipped. The principle of accident handling is efficiency, convenience and speed.

[0003] Although the above general process tools are relatively widely used, they also have many shortcomings:

[0004] 1) The jar sub needs to be equipped with different types of reducers and buckles according to different drilling tool specifications. It needs to be lowered to the position closest to the stuck point, which cannot achieve the goal of a tool with multiple uses and can be used immediately after installation.

[0005] 2) Generally, the drilling tools in the accident well cannot be completely reversed to release the jam, resulting in waste of drilling tools and affecting the drilling trajectory. It is necessary to repurchase some drilling tools and adjust the construction trajectory, thereby increasing construction costs.

[0006] 3) General drilling fluid sticking removal is highly targeted and is mostly used for situations such as hole shrinkage and sticking, but it is not very effective for situations such as point sticking and sand bridges. Utility Model Content

[0059] In order to better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0060] Example 1, as Figure 1 As shown, an upward and downward rebound jam release device includes:

[0061] The impact component 3 of the upward and downward impact rebound jam-releasing device of the present invention can be made of materials such as scrap steel plates. A pneumatic winch (supporting equipment for construction drilling rigs) is used to pull the gravity object 2 to a certain height, and the free fall (impact force) generated acts on the impact component 3.

The purpose is to make the gravity object 2, the drill rod 1 and the impact assembly 3 work better and maximize their efficiency.

[0063] After one working cycle, the stuck drill rod 1 is moved and the lifting height is increased by 2 to 5 cm, and the cycle is repeated until the jam is released.
