Among them, the new diamond composite piece 1913QL-1 project in the same section of the Chuanqing drilling 30533 team in the same block, the realization of a single drill bit to drill three wells to complete the drilling index. After testing, it can only complete the status quo of a single well compared with the current advanced products in China. The product has obvious advantages in wear resistance, impact resistance and drilling speed. The initial experiment has been well received by users.
In the experiment of Changqing Oilfield Company and Chuanqing Drilling Company, the single-well over-sand amount exceeds 150 squares, which guarantees the 15-stage grading fracturing of horizontal wells. The blasting nozzle has the characteristics of high hardness and strong wear resistance. In the high-pressure, high-speed corrosive working fluid, it has the characteristics of small deformation and small wear under long-time erosion, and achieves the performance of similar foreign advanced products in performance.
The successful development of these products has filled the gap in the development of super-hard advanced materials by Xi'an Petroleum University, which has enhanced the professional influence of the school, established a leading position in the industry, and laid a solid foundation for the next industrialization and external cooperation. It has been favored and approached by many investment institutions.
High temperature resistant glass ceramic high temperature resistant glass ceramics is a new material developed with the application of new processes such as sintering and sol-gel methods in the preparation of glass ceramics. When high temperature resistant crystals such as mullite, spinel, garnet are precipitated in the glass ceramic and the content is high, the material can withstand high temperatures. For example, in the garnet glass ceramic, not only the high temperature resistant crystallites but also some mullite crystals are precipitated, and the residual glass phase is surrounded by crystals, which can be used at a high temperature of about 1400 °C.
