Carbon Additive is a product that is added to molten steel. Carbon Additive includes Calcined Petroleum Coke, Graphite Petroleum Coke, Calcined Anthracite Coal, Electrical Calcined Anthracite, Natural Graphite etc. For the steel-making industry, the most suitable carbon additive is calcined petroleum coke with fixed carbon of 98.5%min. Sulfur in calcined petroleum coke is a crucial element, for sulfur impacts the quality of steel. The lower the sulfur, the better quality of calcined petroleum coke. The sulfur content of calcined petroleum coke is decided by the sulfur content in petroleum coke. High Carbon has been the ORIGIN for many trading companies and metallurgical factories when they look for qualified carbon additives Carbon Additive Low Backwashing Intensity Filter Material,Low Phosphorus Content Coal,Low Phosphorus Ningxia Anthracite NINGXIA PANSON COAL AND CARBON CO., LTD , http://www.nxpanson.com
At the end of July, the new cone-PDC composite drill developed by the gemstone machinery Chengdu Gemei Company completed the test in the Ma 002-H1 development well constructed in Sichuan Maliuchang, and the first test on the field was successful. This drill bit fills the gap in China's petroleum drill bit products.
Ma 002-H1 Well is a development well of Southwest Oil and Gas Field Company located in the construction of Maliuchang, Sichuan, with a designed well depth of 3,114 meters. The drill bit of this test was drilled from the well depth of 1015.86 meters to 1232.34 meters, passing through the four to two layers, the total footage was 216.48 meters, the pure drilling time was 51.42 hours, and the average hourly mechanical drilling rate was 4.21 meters. The on-site drilling test was successfully completed. Good results.
The research on the cone-PDC composite drill bit is one of the key scientific research projects of China National Petroleum Corporation. The roller-PDC composite drill bit combines the rock breaking principle and advantages of the roller cone bit and the PDC bit to realize the composite structure scheme including the PDC bit structure and the cone bit structure on one drill bit, and solves the problem of speed increase in deep complex formation drilling. .
The official production of the cone PDC bit fills the domestic gap
Abstract On August 22nd, the cone-PDC composite drill bit was mass produced in the gemstone machinery Chengdu Gems Company. At the end of July, the new cone-PDC compound drill bit developed by Gems Machinery Chengdu Gems Company completed the test in the Ma 002-H1 development well constructed in Sichuan Maliuchang...
