Hydraulic fracking technology widely used in shale gas development drilling

Hydraulic fracking technology is one of the core technology of shale gas development, widely used in shale gas development drilling.Well drilling in shale gas well production, long production time, shale gas development is the most reasonable way, horizontal well location should try to choose natural fracture system development, organic enrichment, low Poisson's ratio and Young's modulus high places.
There are low-pressure horizontal drilling underbalanced drilling, and rotary steerable drilling control pressure drilling technology, low pressure air underbalanced drilling technology is more mature, controlled pressure drilling technology can be a good problem to overcome borehole collapse, rotary steerable drilling technology is shale gas horizontal drilling technology development. Horizontal drilling combined with reasonable measures to increase production is a necessary means of shale gas production increase.
