Well Pipe Casing Damage and Repair Methods

The quality of well pipe casing cementing is crucial to the success of exploratory wells and is key to oil and gas testing. For production wells, the quality of the casing directly affects their lifespan and economic benefits. In the production process of oil fields, once the well pipe casing is damaged, it can disrupt the injection-production well network, severely impacting normal production. To restore normal production, the damaged casing must be repaired to avoid shutdown issues. This article discusses the causes of well pipe casing damage, types of damage, and repair methods, and proposes preventive measures to enhance the economic benefits of oil field development.

Galvanized Seamless Steel Pipe

The most popular products on the market are welded pipes, galvanized pipes, square pipes, spiral pipes and seamless pipes. The circulation of galvanized seamless pipes is very small, and they are generally produced on order. So are you familiar with galvanized seamless pipes? Galvanized seamless steel pipe is a steel pipe product with superb manufacturing technology. It is made of high-quality carbon steel or alloy steel materials through a series of processing processes to make seamless steel pipes, and then galvanized on the surface. Galvanizing is an important method to protect the surface of steel. By covering the surface of the steel pipe with a zinc layer, the steel pipe can be effectively prevented from being damaged by oxidation, corrosion, and corrosion. Therefore, seamless galvanized steel pipes have the advantages of corrosion resistance, wear resistance, pressure resistance, and long service life.

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. The screen casing is a separator used to separate liquid sand in oil and gas wells or water wells. Like the slotted casing, its main function is to prevent sand. Due to the geological conditions of the oil wells, different sand layers use different steel grades and types of pipes (slit, drilled, wire-wound, bridge type, composite) for oil exploitation. The screen casing complies with API 5CT specifications.

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.
