Background technology
Shale gas are a kind of cleaning, low-carbon (LC), Unconventional gas assigned with absorption, dissolving, free state in mud shale
Resource.Shale gas exploitation has the advantages that production life of well is long, yield is high and the production cycle is long, it has also become Global Oil and Gas Resources are explored
The new highlight of exploitation.Extensive hydraulic fracturing being used shale gas well, its know-why is the intrinsic fracture or people using reservoir more
For induction produces Fracture System, the fracturing fluid containing various additives to inject stratum under high pressure, further expand reservoir
Fracture network, then improve Reservoir Fracture network system by proppant supporting crack, so as to reach the purpose of volume increase.Wherein,
Based on riverfrac treatment, riverfrac treatment liquid low cost, rock permeability is high, be easy to thoroughly cleaning enter gas-bearing formation, especially hypotonic
Good effect is shown in saturating oil-gas reservoir reservoir reconstruction.However, riverfrac treatment has the disadvantage that:1. horizontal well and hydraulic fracturing
Technology needs to consume substantial amounts of freshwater resources;2. the waste liquid that shale gas exploitation is produced includes complicated composition, such as heavy metal, dirt
Deng;3. methane can discharge into water body and pollute as the main component of natural gas.Therefore, shale gas exploitation is to fresh water
Wilderness demand forms competition with agricultural and service water, exacerbates the present situation of freshwater resources shortage.
