So-called hydrofracturing method refers to that the high pressure water that is mixed with sandstone and chemical substance is injected to oil well breaks through rammell, discharges shale gas.For being low-permeability oilfield, unconventional oil-gas reservoir volume increase, the effect of hydraulic fracturing technology is obvious to all.But the harm of fracturing also should not be underestimated.
Each hydraulic crushing needs millions of tons water, and for China such Yi Ge lack of water big country, the great lot of water resources expending in its fracturing process is quite surprising.Although what a large amount of chemical agents that add in fracturing fluid injected is deep formation, can not cause direct pollution to underground water, in the long run, still has potential hazard.After fracturing finishes, return discharge opeing processing bad, also can cause rugged environment to pollute.At present, fracturing is controversial in a plurality of countries, and French Government has even been promulgated ban to it.
And than traditional hydraulic fracturing technology, there are not the problems referred to above in the anhydrous pressure break of carbon dioxide.It has following advantage:
Without water, can not cause water-sensitive, water blocking damage to reservoir, side by side alleviated the pressure to environment and water resources;
Without residue, can not cause residue injury to reservoir and supporting crack permeability;
Energy increasing function, after earth pressure release, dioxy carbon gas expansion, can realize the row of returning rapidly;
Carbon injects reservoir, realizes greenhouse gases recycling.
Carbon dioxide supercharging equipment is the nucleus equipment of the anhydrous fracturing work of carbon dioxide.In the anhydrous fracturing work of carbon dioxide, carbon dioxide supercharging equipment can carry out pressurize and pressurization to liquid carbon dioxide, reduce pressure surge feed flow not enough, avoid pressure drop to produce dry ice, carbon dioxide that can separation of vaporization is also discharged, for fracturing unit truck provides the liquid carbon dioxide of large discharge capacity, meet the needs of fracturing unit truck.
In sum, the future develop of carbon dioxide supercharging equipment is boundless.But current carbon dioxide supercharging equipment is main dependence on import also, and its core technology is grasped and monopolized by offshore company, and price is high, delivery date is long.
