Shale gas development needs facing the scientific and technological research (2)

3, shale reservoir geophysics evaluation techniques

In the digestion and absorption of foreign technology, based on the conduct complex terrain and geological conditions,Unconventional gas seismic acquisition and processing and interpretation, shale gas well logging and other geophysical and reservoir fine description and evaluation criteria of identification technology, organic-rich shales and gradually form and gas-bearing geophysical identify key technologies, the establishment of shale gas reservoir parameter identification technique for determining the  shale gas  "sweet zone" to provide technical means.

4, horizontal shale gas well drilling and completion techniques

Learn from conventional oil and gas reservoirs and low permeability gas reservoir drilling and completion techniques, focusing on shale gas drilling and cementing aids, directional wellbore trajectory optimization, long sections of horizontal well drilling and casing optimal and fast completion, adaptability oil based drilling fluid system and other research,frac sand companies and constantly improve equipment adaptability, reliability and security, forming a suitable geological conditions of shale gas drilling and completion techniques.
