Performance Analysis of Casing pipe

Casing pipe is an important equipment for oil drilling. Its main equipment also includes drill pipe, core tube and casing, drill collar and small-diameter steel pipe for drilling. Casing pipe is a vital component in the process of oil well drilling and production, and is known as the lifeline for maintaining the operation of oil wells. Due to different geological conditions and complex stress states, the combined effects of tension, compression, bending and torsion stress act on the pipe body, which puts higher requirements on the quality of the casing itself. Once the casing itself is damaged for some reason, it may lead to a reduction in production of the entire well or even scrapping. Therefore, it is very important to understand the types, specifications, use standards and physical performance inspections of casing pipe.

The characteristics and advantages of steel pipe piles

Steel pipe piles, also known as steel piles, can be made into various sections that are conducive to improving bearing capacity according to load characteristics. The pile ends of tubular and box-shaped piles are often made open to reduce the soil squeezing effect during the pile sinking process. When the axial compressive strength of the pile wall is insufficient, the soil squeezed into the tube and box can be excavated and poured with concrete. Steel pipe piles, as a pile foundation material widely used in foundation engineering construction, have been widely used in buildings, bridges, tunnels and other fields due to their unique structural and material advantages. This article will discuss the advantages of steel pipe piles in detail from multiple angles.

PVC slotted casing VS steel slotted casing

In the development process of coalbed methane wells, the selection of slotted casing has an important impact on the production and stability of the well. At present, steel slotted casing and PVC slotted casing are two commonly used types of slotted casing. Steel slotted casing is generally made of seamless steel pipe or welded pipe. This article will explore the difference between these two slotted casings and analyze their advantages and disadvantages in practical applications.

Advantages of the new pup joints

Oil casing pipes are important pipelines that transport crude oil and natural gas from oil and gas layers to the surface after drilling. In this process, the oil casing pipe needs to withstand considerable pressure. Therefore, as an important accessory for connecting oil casing pipes, the performance of the pup joint directly affects the service life and work efficiency of the oil casing pipe. This article introduces a new type of convenient double-headed oil casing pipe pup joint for oil fields to solve many problems of traditional oil pipe pup joints, such as inconvenient to take, easy to scratch, slow flow rate and impurity blockage.

Common specifications of drill pipe

Oil drill pipe is a key tool commonly used in oil and gas exploration and drilling operations. It consists of multiple sections of drill pipe, and its main function is to transport the drill bit and drilling fluid to the bottom of the well and bring rock samples back to the surface. Some drill pipes are made of seamless steel pipes through secondary processing. The inner diameter size of the drill pipe is crucial to the safety and efficiency of drilling operations. The following is a detailed introduction to common drill pipe specifications and their applications:

Precautions for producing flanges

Flanges are important connecting parts used in pipeline systems. They belong to pipe fittings like elbows, valves, and tees. Flanges are mainly used to connect pipelines, shafts, and equipment. They are used in conjunction with gaskets and bolts to achieve a sealed connection between fixed pipelines and rotating or reciprocating equipment. This connection method is very common in various industrial applications. However, there are some inevitable problems in the production process of flanges, which may affect the quality and performance of the flanges, thereby affecting the safety and efficiency of the entire pipeline system. This article will introduce in detail some problems that flanges are prone to in production and their solutions.

Advantages of screen casing sand control technology

In recent years, with the rapid development of the petroleum and mining industries, the maturity of oil well drilling technology in desert areas, the increased efforts in the mid- and late-stage development of oil fields, the rise of large-scale offshore oil production, and the vigorous development of geothermal wells, brine wells, and deep water wells, the demand for screen casing consumption has continued to increase. The traditional drilling and production process of drilling, casing pipe, and blasting and perforating can no longer adapt to complex terrain. Due to the need for modern drilling and production technology with high efficiency and high recovery rate, screen casings have been widely promoted and used in underground liquid drilling and production in the mining industry.

What are the uses of casing pipes?

As the core industry of global energy supply, the production process of the oil and gas industry is highly dependent on various special equipment and materials. Among them, oil casing pipe is used in the drilling, mining and maintenance of oil and gas wells. Oil casing pipe is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the entire oil well during the drilling process and after completion. Each well uses several layers of casing pipe according to different drilling depths and geological conditions. After the casing pipe is lowered into the well, cement is used for cementing. Unlike oil tubing and drill pipes, it cannot be reused and is a disposable consumable material.

Drill collar connection design

Drill collar connection is a vital part of oil and gas drilling operations. The drill collar is connected to the drill bit at the bottom and the drill pipe at the top. The drill collar is located at the bottom of the drill string and is the main component of the lower drill string assembly. Its performance and reliability are directly related to the success or failure of the entire drilling project. This article will discuss the characteristics of drill collar connection in detail, covering API connection standards, phosphate coating treatment, stress relief function, cold rolling treatment, slide and elevator grooves, cleaning and covering specifications, as well as clamping pressure and calibration, and explain how these characteristics work together to improve the performance and durability of drill collar connections.

Common knowledge about piling pipe

In coastal and inland alluvial plain areas, the soil is often a very thick (50-60m deep) soft soil layer. When the upper structure load is large, this type of foundation often cannot be directly used as a bearing layer, and the low-com pressibility bearing layer is very deep. When using general pile foundations, a pile hammer with a large impact force must be used when sinking piles. It will be difficult to adapt to conventional reinforced concrete and prestressed concrete piles. For this reason, steel pipe piles are often used to reinforce the foundation. Therefore, pile pipes have been widely used in various countries.

Will leakage occur if the pup Joint is damaged?

Leakage accidents are one of the most common accidents in the oil industry, among which pup joint leakage accidents are also common. Some people worry whether all pup joints are prone to leakage accidents, so are oil casing pup joints prone to leakage accidents? According to various deeds, the cause of pup joint damage and leakage is generally due to aging, crack enlargement, and damage of high-pressure pipelines. When the casing short-circuit is damaged, high-pressure oil and gas will leak out of the casing and tubing, causing serious environmental pollution and personal injury accidents. The following will introduce some causes of pup joint accidents and solutions.
