Application and development of special buckles for oil and casing pipes

Posted by BAOWI STEEL MANUFACTURING CO.,LTD on May 11th, 2024

In recent years, special buckles for oil and casing have been widely used in mining in oil-producing countries such as Europe, the United States, and the Middle East. Especially in difficult-to-produce well conditions such as deep wells, ultra-deep wells, high-pressure gas wells, heavy oil thermal recovery wells, and heavily corroded wells, various special oil casings are often used.

Manufacturers in the United States, Japan, France, Germany and other developed countries are even developing new special threaded joints to improve engineering safety, reliability and oil well life.

The exploitation level of China's major oil fields has reached the mid-to-late stage of secondary oil recovery, and the requirements for mining conditions are relatively high, making the working conditions of special oil pipes even worse. Therefore, the connection strength and sealing performance of the threaded part are stricter. It was under this circumstance that special buckles for oil and casing began to be widely used. It is estimated that the production and use of special buckles for oil and casing pipes in China have reached more than 50% of the total number of oil pipes, and the proportion will become higher and higher.

The design and production of special buckles for Chinese oil and casing pipes began more than 10 years ago, but most of them imitate foreign products. In recent years, with the development of many oil and gas fields, the amount of oil and gas drilling projects has increased day by day, while the well conditions have become worse and worse, and the requirements for oil well pipes have become higher and higher. In order to fill the domestic gap and replace foreign products, my country's large-scale oil well pipe production enterprises have gradually increased the strength of designing and producing more advanced special button hole pipes. For example, Baosteel has developed special fasteners such as BDS and TDS, Tianshan Iron and Steel Co., Ltd. Xianbai developed TP-CQ special buckle, Baoguan cooperated with Changqing Oilfield to develop BC special buckle, and other companies are also working hard to develop different types of special buckle products in order to occupy a place in the future oil well pipe market.

However, the special buckle for oil and casing is a product with high technical content, difficult processing, strict quality requirements, and strong theory and practice.

Each steel pipe needs to be processed with more care. Moreover, the special buckle design must have a mature development team, accumulate and explore certain experience, and undergo a lot of calculations, and can be used in oil fields under various conditions and very strict test verification. At the same time, after the successful underground test, it is hoped to expand the scope of use. Due to the increase in drilling and production costs in western oil and gas fields, oil fields are more cautious in using oil well pipes. Therefore, there is still a long way to go before the promotion and application of special buckles for domestic oil and casing pipes. In this case, the well control manufacturer should cooperate.

Oil casing is the lifeline to maintain the operation of oil wells. BAOWI STEEL MANUFACTURING CO., LTD adheres to the principle of quality first and service first when producing oil casing and oil pipes, and provides customers with the best quality oil casing residual products.
