High temperature type
3.1.2 According to the circulation direction of the drilling fluid in the salvage device during drilling, it is divided into three types, as shown in Table 2. Table 2 Classification of salvage devices (according to the circulation direction of drilling fluid in the salvage device) Type
Reverse circulation type
Forward circulation type
Non-circulation type

4.6 The magnet and the pole core should be fixed reliably without loosening or displacement. 5 Test method
5.1 If the materials of the joint and the barrel need to be tested for mechanical properties, they should be tested in accordance with the relevant provisions of GB/T228. 5.2 The thread of the drill pipe joint shall be inspected with a thread gauge in accordance with the provisions of GB/T4749. The thread of the oil pipe joint shall be inspected with a thread gauge in accordance with the provisions of GB/T9253.2.
5.3 Normal temperature suction test:
5.3.1 The test shall be carried out with a tensile test equipment, and the reading error of the test instrument shall not exceed 2%. Each suction test shall ensure that the suction time of the salvage device and the armature is 4 to 5 minutes.
5.3.2 The material of the armature used in the test is 45 carbon steel and the shape is cylindrical. The outer diameter of the cylinder is the maximum outer diameter of the salvage, and the thickness is 50mm
5.3.3 When the armature test surface is completely adsorbed by the salvage, pull the armature away from the salvage along the axis direction. The measured tensile force value is the suction value at normal temperature.
5.4 High temperature suction test:
5.4.1 Heat the ordinary salvage to 120℃±5℃, and heat the high temperature salvage to 250℃+5℃, and keep warm for 2h. 5.4.2 Test again according to the methods of 5.3.1, 5.3.2, and 5.3.3. The measured tensile force value should meet the suction value specified in Table 3. 6 Inspection rules
