Description
Technical field
The present invention relates to the technical field of shale gas reservoir reconstruction, shale physical property is joined more particularly to a kind of impact shock
The analysis method of number influence.
Background technology
Shale gas refers to preservation in rich organic matter mud shale and its interlayer, to adsorb with free state as the side of being primarily present
The Unconventional gas of formula, composition is a kind of cleaning, efficient energy resources and industrial chemicals, is mainly used in based on methane
Resident's combustion gas, city heat supply, generating, motor vehicle fuel and Chemical Manufacture etc., it is widely used.Typically need not in shale gas production process
Draining, the production cycle is long, generally 30 years~50 years, and exploration and development success rate is high, is worth with higher industrial economy.China
Shale gas resource potential is big, and China's shale gas mining resources amount is in 25 tcms according to a preliminary estimate.
Shale gas exploitation has the advantages that production life of well length and production cycle are long --- most of aerogenesis shale distribution
Extensively, thickness is big, and universal gassiness so that shale gas well can chronically stablize aerogenesis.But shale gas permeability of reservoir is low, opens
Adopt difficulty larger.As what world energy sources was consumed constantly rises, the unconventional energy resource including shale gas is increasingly by weight
Depending on.The states such as America ＆ Canada have realized shale gas commercial development.The reservoir of shale gas reservoir is general in low hole, low-permeability
Physical property characteristic, the resistance ratios conventional gas of air-flow is big, and all wells are required for implementation reservoir fracturing improvement could be mined.
On the other hand, shale gas recovery ratio is lower than conventional gas, and conventional gas recovery ratio is more than 60%, and shale gas is only
5%~60%.Low yield affects people to be keen to it, and the U.S. has had some advanced technologies to improve the production of shale gas well
Amount.The reservoir of Chinese shale gas reservoir difference compared with the U.S., the shale gas-bearing formation buried depth in such as Sichuan Basin is bigger than the U.S.,
The shale gas-bearing formation depth in the U.S. is at 800~2600 meters, and the shale gas-bearing formation buried depth in the Sichuan Basin is at 2000~3500 meters.Shale gas
The increase of layer depth undoubtedly adds difficulty again at us in this jejune technology.
With advances in technology, the expense of shale gas well fracturing methods is also gradually reduced.Horizontal well is shale gas reservoir success
Another key factor of exploitation.According to American Experience, the average daily gas production and final gas production of horizontal well are the 3-5 of peupendicular hole
Times, gas production rate then improves 10 times, and 2-4 times of the cost of horizontal well then not enough peupendicular hole.Therefore, the popularization and application of horizontal well
Accelerate the development process of shale gas.Because shale gas develops larger, individual well control recoverable reserves height (up to 6,000
Incomparably), the individual well daily output after taking measures is up to 30,000 sides.In addition shale gas well yield lapse rate is low, easily realizes 30-
The stable production period of 50 years, therefore the economic value of relative high yield can be realized.
The production technique of current shale gas mainly includes horizontal well drilling completion technology and staged fracturing technology, riverfrac treatment skill
Art, multiple fracturing technique and newest synchronous fracturing technique, these technologies are just improving constantly shale gas well yield.
Shale gas exploration and development is successful in the U.S., and the research of domestic shale gas is also in the starting stage, but makees
For a kind of unconventional energy resource having a high potential, just gradually paid attention to by national associated mechanisms and each oil company.Shale gas is stored up
The research of layer renovation technique is always the focus and emphasis of developer's research.
Shale gas stimulation technology generally comprises hydraulic fracturing and acidifying.It can be entered by conventional oil pipe or coiled tubing
Row construction.It is external the old well of new well increase production again or second completion in, through carrying out construction operation frequently with coiled tubing.It can be used for
Branch horizontal well Hydro Fracturing Stimulation Treatment has a variety of, including nitrogen foam pressure break, gel fracture, multistage fracturing, riverfrac treatment, synchronization
Pressure break, hydraulic jetting fracturing, refracturing etc..Multistage fracturing, riverfrac treatment, synchronous pressure break, hydraulic jetting fracturing and repetition are pressed
It is the conventional technology of current shale gas hydraulic fracturing to split.Hydraulic fracturing is the agent technology of shale gas exploitation, and how to obtain page
Rock physical parameter is the key of shale gas exploitation.
