In the process of oil and gas exploitation, blowout accompanied by toxic and harmful gas occurs when the local layer pressure is not well controlled. Blowout accident is one of the most common and dangerous accidents in the field of oil and gas exploitation. In order to prevent the occurrence of such accidents, INTLEF Bolu Tianbao has been committed to the development and manufacturing of safer and more efficient well control equipment with professional technology and advanced equipment to adapt to the site conditions and construction requirements.

In July, the 35-70QL quick-release side door hydraulic locking ram preventer and its blowout preventer group developed, produced and manufactured by INTLEF Bolu Tianbao were officially delivered to a key well site in Sichuan and Chongqing area of petrochina Daqing Drilling Company after passing multi-party testing and inspection.

The BOP serving the site in Sichuan and Chongqing area is configured as 35-70U type 1 double 2 single 1 ring. According to the characteristics of high underground pressure and high concentration of hydrogen sulfide gas in Sichuan and Chongqing area, the blowout preventer group adopts special anti-sulfur and anti-corrosion technology treatment, and adopts new product structural characteristics such as QL quick-disconnecting side doors and hydraulic locking to make the operation more efficient and safer. The well site occupies less space and other characteristics, for the smooth production of users, safe operation escort, in the use of the site has been greatly recognized and appreciated by customers.
