  Specifications of screen casings

  In oil drilling operations, screen casings are an important equipment, and are often used for early completion or oil production to prevent sand. At present, the most commonly used screen casings are wire-wound screen casings. The manufacturing method of this screen casing is: winding a certain cross-section of steel wire evenly distributed on the surrounding screen rods or on the metal liner with holes and welding it firmly, and leaving a certain gap as the screen hole.

  Design and Application of Piling Pipe

  Piling pipe is a commonly used foundation engineering material used in the foundation construction of large structures such as buildings, bridges, and docks. Its main function is to transfer the load of the superstructure to the deep hard soil or rock layer through the pile foundation to ensure the stability and safety of the structure. This article will explore in depth how to improve the cost-effectiveness of foundation engineering through reasonable design and selection of piling pipes.

  What is API 5CT K55 Well Pipe Casing?

  Petroleum and combustible gases (such as natural gas, shale gas, and coalbed methane) are the primary energy sources consumed by humans today. In recent years, the global consumption of fossil fuels has continued to grow, leading to an increased demand for corresponding equipment, such as tubing and casing, well pipe casing, drill pipes, drill collars, etc. In the process of oil and gas exploration and development, well pipe casing is an essential material and equipment, accounting for 20% to 30% of the total well construction cost. The steel grades of oil well pipe casing include H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Today, we will focus on the K55 grade well pipe casing.

  Waterproof coating casing pipe

  The use of oil casing pipe in oil wells is very common. Due to the complexity of the stress state in the well under different geological conditions, the oil casing pipe must meet high quality standards in the process of bearing tension, compression, bending and torsion stress. Any damage caused by the casing's own defects may lead to a decrease in oil well production or even the scrapping of the entire oil well. Therefore, it is crucial to understand and select the appropriate waterproof coating for the protection of oil casing pipe.

  Drill collar weight and size standards

  Drill collars are thick, heavy tubular objects used in the drill string just above the drill bit, with the drill pipe connected below. They provide rigidity and weight to the drill bit to help control direction and improve drilling efficiency. Heavier drill chains apply more force to the drill bit to crush the rock and keep the hole vertical. Their weight also increases the tensile strength of the drill pipe to prevent bending. Generally, longer and heavier drill boats are more popular for deeper and more challenging drilling environments. Typical drill collar lengths range from 30 to 90 feet. The length and weight of oil drill collars need to be calculated and selected according to the specific drilling situation. The drill collar is at the bottom of the drill string and is the main component of the lower drilling tool assembly. Its main characteristics are large wall thickness (generally 38~53mm, equivalent to 4~6 times the wall thickness of the drill pipe), large gravity and rigidity.

  What is Threaded Pup Joints?

  Threaded pup joints are commonly used fittings for industrial pipe connections. Depending on the specific application, threaded pup joints can be divided into single-threaded pup joints and double-threaded pup joints. A single-threaded pup joint has external threads on one end, while a double-threaded pup joint has external threads on both ends. These joints serve the purpose of connecting, extending, and converting in various engineering projects. This article will provide a detailed introduction to the usage methods, standards, manufacturing materials, machining precision, load-bearing capacity, corrosion resistance, service life, threaded connection performance, testing methods, and marking, packaging, transportation, and storage of threaded pup joints.

  What are the types of drill collars?

  The drill collar is an important part of the drill string. Its main function is to apply drilling pressure to the drill bit and pump drilling fluid, so that the lower drilling tool assembly has greater rigidity, ensure the stability of the drill bit, and reduce the problem of well deviation. Since the drilling pressure is formed by the weight of the drill string, the compressive stress of the lower part of the drill string is relatively large. Usually, the drilling pressure value is greater than the critical value of the pressure rod stability of the drill string, which will cause the drill string in the lower compressed part to bend under the action of its own weight. During the rotation process, the bent drill string will cause alternating stress, resulting in fatigue damage of the drill string. In order to reduce the degree of fatigue damage and reduce bending stress, drill collars are usually used instead of drill rods in the compressed part of the lower end of the drill string. Drill collars are generally made of thick-walled seamless steel pipes, and the types include cylindrical drill collars, spiral drill collars, non-magnetic drill collars, square drill collars, etc. The following will introduce the characteristics of various types of drill collars and their manufacturing processes in detail.
