It is worth noting that in recent years, Coal seam gas PetroChina, Sinopec, China University of Petroleum domestic enterprises and research institutes to increase the R & D efforts for China's geological conditions, particularly in the fracturing fluid technology.
Currently, foreign patent applications in China, mainly involved for fracturing fluids under general geological conditions, while domestic application relates generally applicable to special geological situation in China fracturing fluid, domestic enterprises should also consider common fracturing fluid patent protected to further expand its technological superiority.
In addition, geological evaluation technology, domestic Chinese Academy of Sciences, PetroChina and Sinopec, led by research institutes and enterprises in the field has formed a certain technical advantages.
Based on the above analysis, it is necessary to natural gas fracking strengthen our country for the special geological conditions of China's shale gas technology development, strive to achieve technological breakthroughs in key areas; second is to support and encourage enterprises and research institutes to increase the rotary steerable drilling geology, pumping can drilling bridge plug staged fracturing and other cutting-edge technology research and development efforts, and actively carry out related patent portfolio.
