Drilling Tool Inspection 
Onshore Oil Drilling and 
Non-Destructive Testing for 
Material Testing 
In the production and manufacturing process of drilling tools, drilling and production equipment facilities and other related products, supervision and management are carried out from two aspects: the effectiveness of the quality system and the compliance of testing and product quality, to ensure that product quality and testing quality are given top priority
1. Customized supervision plan, forming project normative documents, and strictly implementing them during the supervision process
2. Qualication, manufacturing process, schedule, quality control documents, HSE system document review
3. On site personnel allocation, equipment status, organizational structure, number of in production equipment, and other inspection, ling, and risk assessment
4. During the production process, raw material and manufacturing capability management, product subcontracting management, manufacturing process management, non conformance management in manufacturing, setting up supervision control points and supervision methods, nished product acceptance and shipping management, HSE management, etc. are carried out
Covers inspection of drill strings, drilling tools, completion tools, and logging tools. Specic inspection techniques include ultrasonic testing of pipe body weld zones, magnetic particle testing of tool joints, electromagnetic testing of pipe bodies, and dimensional measurement and data recording.
Provides maintenance services for drill strings, drilling tools, completion tools, and logging tools, including operations such as tool joint thread machining.
Covers the engineering, procurement, construction, and commissioning (EPCC) of API-standard maintenance workshops, including design, fabrication, installation, and operational maintenance.
Includes data entry, statistical analysis, maintenance planning, production scheduling, inventory tracking, usage management, real-time monitoring, and automated reporting of inspection results.
Covers inspection of components such as the crown block, traveling block, hook, swivel, top drive, rotary table, drawworks, and mud pumps. Includes ultrasonic testing and magnetic particle testing of structural forgings, and penetrant testing for non-ferromagnetic materials.
Includes blowout preventers (BOPs), control systems, choke and kill manifolds, and separators. Inspections cover ultrasonic thickness measurement and magnetic particle testing of housings and anges; magnetic particle testing and tensile testing of connecting bolts; dimensional measurement of bores; pressure testing of sealing surfaces; and magnetic particle inspection of internal valve components.
Covers key components of equipment such as separators, winches (pneumatic and hydraulic), acidizing and fracturing units, water injection equipment, gas injection equipment, gas lift systems, cementing units, surface testing equipment, emergency kill systems, pump trucks, and coiled tubing units. Inspections include magnetic particle testing and ultrasonic testing of critical areas, as well as pressure testing of pressure-bearing equipment.
Covers inspection of swivel joints, anchor chains, and anchor piles.
Includes inspection of the main deck and bulkheads, ballast tanks and cargo oil tanks, mooring and positioning systems, and support structures of topside modules.
Inspection of lifeboats, rescue boats, and life rafts, including hull thickness measurement, material verication, watertight pressure testing, and aging inspection of hull drain plugs.
