Stabilizers are standard downhole tools in drilling assemblies. Complex downhole situations and accidents related to them often occur during drilling. Despite extensive analysis and improvements by researchers and manufacturers, the problems have not been completely resolved. The Graf project is located in southern Iraq, where multiple wells have experienced downhole stabilizer breakage during operations.
The commonly used automated coating processes for seamless steel pipes, such as oil casing pipes, include the following four methods: Process One Utilizes a spray coating method with linear conveyor systems, applying the coating before, after, and between the rollers to form a coating film. The pipes are then transferred using forklifts and conveyed by
In the petrochemical industry, hydrogen sulfide (H2S) corrosion is a widespread and highly hazardous phenomenon. By analyzing the corrosion mechanism of H2S, this blog introduces various forms of corrosion caused by wet H2S, including hydrogen embrittlement, hydrogen-induced cracking, sulfide stress corrosion cracking, and stress-induced hydrogen cracking. These types of corrosion are closely related to
A forged shaft produced by the company, made of 42CrMo steel with a net weight of 15 tons and using a 24-ton steel ingot, underwent the following production process: Vacuum smelting → casting → forging → post-forging heat treatment → rough machining → ultrasonic testing → quenching and tempering → semi-finish machining → ultrasonic
42CrMo is a commonly used alloy structural steel recognized for its excellent mechanical properties and adaptability to heat treatment. It is widely used in the manufacturing of mechanical components and engineering machinery. Heat treatment is a key process for enhancing the performance of 42CrMo. This article will introduce the characteristics and applications of 42CrMo
42CrMo material has high strength, good toughness, and hardenability, with minimal quenching deformation and no obvious temper brittleness. After quenching and tempering treatment, it possesses a high fatigue limit and resistance to multiple impacts, along with good low-temperature impact toughness, making it widely used in industrial production. During the production of a batch of
In the complex realm of underground operations, various mishaps can occur involving drill pipes, drill collars, and other essential downhole tools. This blog refers to the general terms for various accidents involving drill pipes, drill collars, and other downhole tools and auxiliary tools that occur underground. The drill tools left in the well after
Special steel materials used in marine oil and gas resource development engineering are generally Cr-Ni-Mo stainless steels, super stainless steels, or Ni-Cr-Mo corrosion-resistant alloy materials. These materials are characterized by high pitting resistance equivalent, high purity, and nitrogen alloying. Typical Components and Performance Indicators Components made from these high-alloy materials for marine oil and
Future Prospects of Steel for Petroleum and Petrochemical Industries 2.1 New Material Requirements for Petrochemical Equipment Development The petrochemical industry is currently undergoing a transformation period. On one hand, the future of the petrochemical industry will develop toward large-scale, integrated, digitalized, and environmentally friendly directions. On the other hand, the national "3060" carbon reduction
