Background technique
Shale gas is preservation in rich organic matter mud shale and its interlayer, with absorption and free state for main existing way
Unconventional gas, ingredient belongs to one kind based on methane, with " coal bed gas ", " tight gas ".The formation and enrichment of shale gas
There is itself uniqueness, is often distributed in that thickness in basin is larger, in widespread shale hydrocarbon source rock formation.Shale gas is very
It is already recognized, but is acquired than conventional natural gas difficulty by people, as energy resource is increasingly deficient, as traditional natural
The useful supplement of gas, people gradually recognize the importance of shale gas.Shale gas is present in dry with adsorbed state (about 50%)
Junket root, clay particle and pore surface, minute quantity are stored in that kerogen, natural gas is also deposited in asphalitine and petroleum with dissolved state
Be the siltstone of sandwich-like, silty, argillaceous siltstoue, even generated for natural gas in sandstone formation after, in source
Nearest aggregation in rock stratum shows as typical original place Reservoir model, larger with the difference such as oil shale, oil-sand, asphalt.With it is normal
Gas Reservoirs difference is advised, shale is both the source rock that natural gas generates, and aggregation and the reservoir and cap rock that save natural gas.Therefore
The high black shale of the content of organic matter, high-carbon mud stone etc. are often best shale gas developmental conditions.
Shale also falls within tight rock, therefore can also be included into tight gas reservoir gas.It originates in the Devonian system in the basin A Balaqiya
Shale is crineous and black, and rich organic matter can be a large amount of angry.Reservoir space is based on crack and can be with adsorbed gas and water-soluble
Gas form preservation is low (negative) pressure, low saturation (30% or so), thus is low yield.But it can obtain in Fractured Zone compared with high yield
Amount, the modification measures such as well shooting and pressure break effect might as well.Shale gas exploitation has production life of well long excellent with production cycle length
Point --- it is most of produce gas shale have a very wide distribution, thickness it is big, and universal gassiness enables the chronically stable production of shale gas well
Gas.But shale gas permeability of reservoir is low, and exploitation difficulty is larger.Continuous with world energy sources consumption is risen, including shale gas
Unconventional energy resource inside is increasingly taken seriously.The states such as America & Canada have realized shale gas commercial development.Past ten
In year, shale gas has become a kind of natural gas resource to become more and more important in the U.S., while also having obtained the wide of whole world other countries
General concern.2000, U.S.'s shale gas yield only accounted for the 1% of natural gas total amount；And by 2010, because of hydraulic fracturing, level
The development of the technologies such as drilling well, specific gravity shared by shale gas is more than 20%.Shale gas conveyance conduit due to be typically all it is buried in
Underground, being embedded in underground for a long time is since erosion or animals and plants etc. damage pipeline, and existing detecting instrument structure is multiple
It is miscellaneous, it is not easy to directly be detected at the scene, so that pipe detection use cost is high, the period of detection is long.
In view of the above-mentioned problems, Authorization Notice No. be CN104500981B patent document, Authorization Notice No. CN
The patent document of 204165721U is disclosed based on the mechanism detected to shale feed channel, specifically, in pipeline to be detected
It is provided with ball one and ball two, inflated hose, inflated hose and rubber are provided between ball one and ball two
It is connected to inside ball one and ball two, inflated hose is sheathed with spring, and spring is connect with ball one and ball two, control cabinet
