Shale gas development debate and awareness of the way

Practice shows that the volume of  shale gas  reservoir fracturing obtained only after the initial high yield, but also more conducive to long-term stable; fracture stimulations in our country is the development of shale gas will be the most important technical means.

1 shale gas has been very good in foreign exploitation, and domestic shale gas development and research is in its infancy, urgent research study its production stimulation technique.

(2) production of shale gas fracturing methods used mainly development, including large-scale vertical wells slippery  Hydraulic fracturing  and horizontal wells clustering perforating staged fracturing, transforming ideas for the formation of complex seam net volume modification techniques.

3 main volume of shale gas horizontal wellfracturing proppant fracturing technology drillable bridge plug packer staged fracturing, including segmented cable cluster perforation technology, high displacement, slippery water, large-scale, low-sand ratio fracturing technology, drillable bridge plug packer technology.

4 domestic shale gas is rich in resources, to get effective development and utilization, modification technology is particularly critical fracture stimulation is recommended to carry out the first volume in a straight Inoue fracturing techniques to explore technology, liquid, construction parameters of adaptability and evaluation after pressure effect, after the success of the horizontal well development.

5 for the development of domestic shale gas volume fracturing horizontal well technology, research should focus on pumping drillable bridge plug staged fracturing technology, including the development of drillable bridge plug, perforating technology research grade cable, electric detonating bridge plug seat seal technology and other supporting technologies.
