Increase.2014,3.08 hundred million tons of China's whole year net importation oil, dependence on foreign countries for oil reached 59.5%；Imported gas amount
For 590 billion cubic meters, increase by 11.5% on a year-on-year basis, external dependence degree rises to 32.2%, and the situation risen year by year is presented.
The explored oil-remaining recoverable reserves per capita in China are only that the world is averaged 1/10th of reserves, and wherein Low Permeability Oil/gas is remote
Scape stock number accounts for the 49% and 42.8% of national total resources respectively.Low Permeability Oil/gas proportion in following China's oil and gas production
To persistently it increase.Hypotonic-special low permeability oil field has porosity low, the feature of permeability difference.This geologic feature determines
The difficulty and expense of its oil-gas exploration and exploitation are huge, it is necessary to could obtain the economic exploitation valence using advanced volume increase production technique
It is worth and realizes and is produced in increasing the storage.Therefore implement fracture technology exactly solve to face during China's oil and gas development at this stage it is tired
Difficult one of most effective means.Hydraulic fracturing technology application starts from nineteen forty-seven earliest, has carried out experiment in Texas, USA
Research, and effect of increasing production is achieved, later with the gradual progress of technology, achieve prodigious development.Hydraulic fracturing is mainly
In discharge capacity injection well by ground high pressure pump group by high-viscous liquid to substantially exceed formation absorption ability, immediately near shaft bottom
High pressure is formed, this pressure forms crack after the tensile strength of crustal stress and rock near more than shaft bottom on stratum；Continue to inject
Load fluid with proppant, crack extend forward and fill out with proppant, and crack closure is on proppant after closing well, in well
The sand packed fracture with certain geometric dimension and high flow conductivity is formed near bottom in stratum, oil/gas well is made to reach increasing yield and injection
Purpose.In recent years, external to be widely used in hydraulic fracturing technology in the exploitation of low-permeability oil gas field, and play significant
Effect.According to statistics, the 25%~30% of american petroleum reserves is to reach the economic exploitation condition by fracturing yield increasing.This technology
The oil gas field of original industrial value is set not become the oil gas field with certain production capacity, meaning is considerably beyond a well
Increasing yield and injection effect.In general, after fracturing, the individual well daily output is 3~5 times higher than before pressure break for oil/gas well.Oil simultaneously
Gas well yield can also carry out refracturing before being once decremented to pressure break.
Fracturing fluid is the liquid with certain viscosity that fracturing reform is applied in the process, and fracturing fluid is as a kind of in construction
Carrier conveying proppant enters pipeline, is delivered to stratum, then gos deep into crack, prevents the closure of fissure channel after pressure, extension from splitting
Slit width degree and generation simultaneously support long crack, and then form high flow conductivity channel, meanwhile, fracturing fluid can be viscous from height in the earth formation
Degree is restored to low viscosity and finally realizes the row of returning after driving a well.In addition during formation breakdown the compatibility of fracturing fluid quality, meeting
Play the role of to entire pressing crack construction success or not critical.
