Exploration and development are at an early stage

Conditions of shale gas resource base has its own characteristics, exploration and development at an early stage,Fracturing proppant technology is not mature enough. First, China's shale gas geological formation later in the United States, shale gas reservoirs and shale gas reservoirs in the United States compared to a huge difference in the overall high degree of thermal evolution of organic matter, burial depth is large, such as the U.S. shale gas burial depth of 200 meters to more than 2000 meters, while China Sichuan Basin shale gas burial depth of 1,500 meters to more than 4000 m; Guizhou, Chongqing, Hunan and other places shale thin and often multi-layered rendering together, different levels of partial visible deterioration; shale gas between different regions is difficult to compare between wells references, analogies,ceramic ball even layer more difficult.

Second, China's shale gas resource exploration and development started late, still in its infancy stage. MLR 2005 began preliminary research, there has been no domestic shale gas resource potential and favorable zones for system evaluation and technical pilot test. Third,frac sand companies technological progress is to promote the commercial development of shale gas key factors, while China's shale gas development technology is not mature, critical technologies have not yet achieved a real breakthrough, shale gas development related technologies need to overcome. At present, China's shale gas geological knowledge and engineering techniques is not mature, core analysis, logging and interpretation of reservoir evaluation, and composite oil-based mud, drillable bridge plug, micro seismic monitoring,Proppant etc. Drilling and Completion techniques and tools need to be improved and perfected.
