6.1 Test methods
6.1.1 Product performance tests should be carried out on a simulation test bench. Select high-strength and thick-walled casings with a maximum radial deformation of B~11mm as test casings. Fix the test casing on the base of the simulation test bench. Connect the eccentric roller shaper to the drill string of the test bench, slowly lower it with a drilling pressure of not less than 10~30kN and a speed of not less than 70r/min, and rotate it into the deformed casing for shaping. After the tool passes, lift the drill string and shape it repeatedly until the shaper can pass the deformed section relatively smoothly. After changing the roller combination size several times, the deformed casing reaches 96% of the original inner diameter after trimming. 6.1.2 After the test, disassemble and inspect, and all parts must not be cracked or damaged. 6.2 Inspection rules
6.2.1 The product must be inspected and qualified by the inspection department of the manufacturer, and the certificate of conformity must be issued before it can leave the factory. 6.2.2 The eccentric shaft after heat treatment must be inspected for hardness and non-destructive testing according to the requirements of Articles 5.6 and 5.7. 6.2.3 The roller after heat treatment must be inspected for hardness according to the requirements of Article 5.8. 6.2.4 The joint thread must be inspected item by item according to the requirements of Article 5.5. 6.2.5 If any of the following conditions exist, one set of the product shall be sampled for performance test and inspection: a. The product structure has been significantly changed, b. The product material and process have been significantly changed, c. The cumulative production batch has reached 100 sets or the production volume of each batch exceeds 30 sets. 6.2.6 The performance test shall be carried out in accordance with the method of Article 6.1.1. 7 Labeling, packaging, transportation and storage 7.1 The product shall be marked in accordance with the provisions of SY/Z6008. 7.2 The product shall be packaged in accordance with the provisions of SY5309 before leaving the factory. After the product is packaged, it shall be sprayed with the mark according to the provisions of different transportation such as car, ship and air transportation. a. Name and address of the receiving unit: b. Name and address of the manufacturer: c. Gross weight, net weight and packaging box dimensions (length × width × height). 7.3 The factory technical documents of the product include: a. Product certificate# b. Product instruction manual: 7.4 The product should be kept in a clean, dry and ventilated warehouse. Place it horizontally and do not drop, bump, squeeze or press it. 7.5 Under the condition that the user complies with the provisions in the product instruction manual, within 12 months from the date of delivery, if the eccentric roller shaper does not meet the manufacturing quality standards and affects normal use, the manufacturer shall repair and replace it free of charge. 3 Additional instructions ZB/T E92 012—89 This standard is proposed and managed by the National Technical Committee for Standardization of Petroleum Drilling Equipment and Tools.
