Description
Technical field
The present invention relates to liquid density measurement, the device that the fluid density being specifically related to shale gas detects.
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-seam 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 rock gas in kerogen, bituminous matter and oil with dissolved state and is also present in the siltstone of sandwich-like, silty, pelitic siltstone, even sandstone formation for after rock gas generates, gathering nearby in source bed shows as typical original place Reservoir model, larger with difference such as resinous shale, oil-sand, pitch earth.Different from conventional reservoir gas reservoir, shale is the source rock that rock gas generates, and is also reservoir and the cap rock of assembling and preserve rock gas.Therefore the black shale that the content of organic matter is high, high-carbon mud stone etc. are often best shale gas developmental conditions.
Shale also belongs to compacted 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-shoot 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 source become more and more important of the U.S., have also been obtained the extensive concern of whole world other countries simultaneously.What shale gas gushed out when exploiting is not only gas, be mixed in the unclarified liquid in gas in addition, need to detect these liquid, to verify its composition, the parameter detected comprises the viscosity, density, composition etc. of liquid, and tradition, makes to detect not accurate enough to fluid density because the error detected is large to the mechanism of the Density Detection of liquid, make the judgement for unclarified liquid occur error, cause shale gas correlation parameter to confirm.
