Technical field
The present invention relates to a kind of system, especially relate to component monitoring system in a kind of shale gas recovery process.
Background technology
Shale gas composes to be stored in rich organic mud shale and interlayer thereof, and be the Unconventional forage of main existing way to adsorb with free state, composition, based on methane, belongs to a class together with " coal bed gas ", " tight gas ".The formation of shale gas and enrichment have the feature of self uniqueness, are often distributed in larger, the widespread shale hydrocarbon source rock formation of thickness in basin.Shale gas very early by people cognition, but gather than conventional natural gas difficulty, along with energy resource is day by day deficient, as the useful supplement of conventional natural gas, people recognize the importance of shale gas gradually.Shale gas is present in kerogen, clay particle and pore surface with adsorbed state (about 50%), minute quantity is stored in natural gas in kerogen, asphalitine and oil with dissolved state and is also present in the siltstone of sandwich-like, silty, argillaceous siltstoue, even sandstone formation for after natural gas generates, gathering nearby in source bed shows as typical original place Reservoir model, larger with difference such as oil shale, oil-sand, bitumen.Different from conventional reservoir gas reservoir, shale is the source rock that natural gas generates, and is also reservoir and the cap rock of assembling and preserve natural gas.Therefore the black shale that organic content is high, high-carbon mud stone etc. are often best shale gas developmental conditions.
Shale also belongs to tight rock, therefore also can be included into tight gas reservoir gas.It originates in the Devonian system shale in A Balaqiya basin, is crineous and black, rich organic, can be angry in a large number.Reservoir space is main with crack and adsorbed gas and Water Soluble Gas form can composes and deposit, and being that low (bear) presses, low saturation (about 30%), is thus low yield.But can obtain high yield at Fractured Zone, the modification measures such as well shooting and pressure break effect might as well.Shale gas exploitation has the advantage that production life of well is long and the production cycle is long---and most of aerogenesis shale has a very wide distribution, thickness large, and general gassiness, make shale gas well can stablize aerogenesis chronically.But shale gas permeability of reservoir is low, exploitation difficulty is larger.Along with constantly riseing of world energy sources consumption, the unconventional energy resource comprising shale gas more and more comes into one's own.The states such as America & Canada have realized shale gas commercial development.In past 10 years, shale gas has become a kind of natural gas resource become more and more important of the U.S., have also been obtained the extensive concern of whole world other countries simultaneously.Due to control is not tight when shale gas starts, easily cause component to produce and leak, and shale gas belongs to inflammable and explosive material, makes to cause security incident, therefore, needs to monitor the composition of shale gas.
