TPCQ Premium Thread Casing Pipe 125V for deepest exploratory well
The special casing for deep / ultra deep wells is designed and developed by our company according to the special needs of users, which is suitable for complex and changeable downhole construction environment of ultra deep and complex wells. Through cooperation with oil fields, we have developed 110ksi to 165ksi tp-v series special casing for deep / ultra deep wells, which has been widely used in domestic major oil fields. The product has been used in well Tashen 1 with a drilling depth of 8408m, and has created a new product in well Keshen 7 Ø two hundred and seventy-three point zero five × The 13.84mm TP140V casing runs 7087m in the whole well section, which is the world record. Φ one hundred and thirty-nine point seven zero × 10.54mm tp165v and 143.32mm tp165v × The 12.35mm tp165v ultra deep well casing has been successfully used in Zhongyuan Oilfield, which is the first high-grade oil casing in China.Tianjin forwell energy equipment
According to the characteristics of ultra deep complex wells and the difficulties of drilling operation, the special pipe string structure and special specification casing and special joint form meeting the requirements of special pipe string structure are designed and developed, It can effectively solve the problem that it is difficult to carry out drilling operation safely and reliably in ultra deep complex wells for a long time because there is no suitable steel grade casing and string structure to choose.
(1) Steelmaking: to solve the key technical problems of metallurgical quality, chemical composition control, inclusion shape control of steel, and form the main clean steel production process.
(2) Babbling pipe: the most advanced POF three wheel continuous rolling mill in the world is adopted to ensure the geometric dimension accuracy of casing（ 3) Heat treatment: make reasonable and feasible quenching and tempering temperature and time and quenching medium to make more than 95% austenite
