China's oil and gas equipment manufacturing, no longer low-key!
" After measurement and verification, the average perforation depth of Pioneer 127 ultra-deep penetrating perforation bullet was 2258 mm, and the experimental data was real and valid. " On November 26, at the CNPC logging perforation bomb target shooting experiment site, the American Petroleum Society (API) staff solemnly signed the experiment results data table.
This means that the "pioneer" 127 ultra-deep penetrating perforation bullet independently developed by CNK Well Logging once again set a world record. According to the target experiment effect, each shot can shoot an average of 2.258 meters long perforation holes, and will increase the perforation depth to a new height.
It is particularly worth mentioning that this new world record is another major breakthrough for CNPC logging after the 127 ultra-deep penetration perforation bomb in 2017, making "China Creation" the world ahead.
perforation is known as the "first kick" of oil and gas exploration and development. It is to shoot the perforator down to the target hierarchy of oil and gas well , and the perforation bullets penetrate the casing, cement ring and into the formation in turn, establishing a reliable and effective channel between the formation and the wellbore to meet the needs of hydraulic fracturing fluid, polymer injection and other injection into the formation and oil and gas output, thereby strongly supporting the efficient development of oil and gas reservoirs.
It can be said that perforation bullets are the core product of perforation technology. The perforation depth of perforation bullets directly affects the fracturing effect and the production capacity of oil and gas wells .
Therefore, in order to achieve better reservoir transformation effect, CNK logging began to deepen its perforation equipment manufacturing field more than 20 years ago, and finally took the lead in China to break through the technical bottleneck that restricts the depth of perforation bullets. By innovating the metal drug-type cover structure, explosive energy control technology and drug-type cover preparation technology, the utilization rate of explosive explosion energy and the ability of jet penetration are greatly improved, and the performance of perforation bullet penetration is achieved.
Looking back at the road, the R&D of CNPC well logging can be described as one step at a time, leading the domestic perforator performance indicators to the international leading position.
2001, CNPC Logging was the first in China to develop a 1-meter perforation bullet with a piercing depth of 1080 mm, leading the domestic perforation depth into the "1-meter era"; in 2010, CNPC Logging developed a "pioneer" perforation bullet reached 1539 mm, leading the domestic perforation depth into the "1.5-meter era"; in 2014, CNPC Logging developed a "pioneer" perforation bullet passed the inspection and certification of the American Petroleum Society (API), and the maximum penetration depth of the 127 ultra-deep penetration hole bullet was fixed at 1730 mm, creating a domestic perforation depth record...
Hard work will reap what you gain! Compared with conventional perforators, the "pioneer" ultra-deep penetration perforator developed by CNPC has the characteristics of large penetration, regular eyelets, no pestle blockage, and low damage. The perforation depth of is increased by more than 60%, and the oil and gas leakage area is increased by more than 30%, which can induce effective communication between fracturing cracks and natural cracks to a greater extent, and reduce the reservoir rupture pressure and reduce the difficulty of hydraulic fracturing implementation. It is suitable for perforation completion operations of low permeability, low porosity, and high-tight oil and gas layers.
As of now, CNK logging has developed and formulated 18 specifications and models of "Pioneer" series ultra-deep penetrating perforation bullet products, meeting the needs of Φ40mm to Φ127mm series perforation guns, meeting the perforation needs of various complex geological conditions, and achieving the maximization of oil and gas production capacity.
For many years, with its strong technical strength and advanced manufacturing technology, the "pioneer" ultra-deep penetrating transducer of the oil logging has seized the technical high ground of high-performance perforator in one fell swoop.
data shows that the "Pioneer" ultra-deep penetrating perforation bullet has been produced and sold more than 5 million units, and has been widely promoted and applied in oil companies such as PetroChina, Sinopec , Yanchang, Shell, Total, and exported to 22 countries such as Azerbaijan , Turkmenistan , India, and has achieved industrial production and large-scale application.
