The principles and steps of falling objects and salvage

Dezhou Jingmei Petroleum Machinery company  is a downhole tools manufacturers .We produce high quality downhole tools.

Today we share the  principles should be followed in the methods and steps of falling objects and salvage.
1.Understand the basic situation of including the structure of the well, the cause of the litter and litter in the depth of underground and there is no deformation and sand burial, can play the lead mould or logging heuristic when necessary, the location and shape analysis of objects fall into a well.
2.Choose the right fishing tools or to design and make tools according to the condition of falling objects, we should consider the problem of falling objects and cards, calculate the maximum load that may be encountered in fishing, and choose the tools and equipments with enough strength.
3.The bar pipe should consider the use of hook and shoes, so as to facilitate the falling fish into the tool.
4.Rope litter will not fall like the bottom rod and tube type fall, but in the middle of scattered, shape is not fixed, and the depth of the fish morphological is not easy to grasp, it is easy to cause over fishing drill.
Therefore, when the tool is selected, the large head pressure plate (also called the limit plate) should be considered. The diameter of the press plate should be larger than the difference between the inner diameter of the casing and the diameter of the falling object.
5. You can judge whether to catch the falling object according to the change of the suspended weight, and the light weight falling object should judge whether to catch the falling object according to the characteristics of the tool or the change of the fishing depth.
6. When necessary, the auxiliary fishing treatment can be taken into consideration by the milling method.
