Description
Technical field
The present invention relates to a kind of system, especially relating to a kind of based on improving the system detecting validity.
Background technique
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 significance 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, asphalitine and oil with dissolved state and is also present in the siltstone of sandwich-like, silty, argillaceous siltstoue, 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 petroliferous shale, oil-sand, mineral pitch.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 dense rock, therefore also can be included into tight gas reservoir gas.It originates in the Devonian system shale in A Balaqiya basin, is fuscous 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 manufacture 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.2000, U.S.'s shale gas output only accounted for 1% of rock gas total amount; And by 2010, because the development of the technology such as fracturing, horizontal drilling, the proportion shared by shale gas was more than 20%.Shale gas conveyance conduit is owing to being generally all buried in underground, being embedded in underground is for a long time because corrode or animals and plants etc. damages pipeline, the validity that existing detecting instrument detects when detecting pipeline can not control, its error is large, cause the actual conditions of pipeline to judge, there is potential safety hazard.
Summary of the invention
The object of the invention is to overcome the validity that above-mentioned existing detecting instrument detects when detecting pipeline can not control, its error is large, the actual conditions of pipeline are caused to judge, there is the problem of potential safety hazard, devise a kind of based on improving the system detecting validity, this system utilizes the change of air pressure, the situation of pipeline wall can be detected exactly, operator can be judged accurately to the situation of pipeline, avoid occurring potential safety hazard, solve the validity that existing detecting instrument detects when detecting pipeline can not control, its error is large, the actual conditions of pipeline are caused to judge, there is the problem of potential safety hazard.
Object of the present invention is achieved through the following technical solutions: based on improving the system detecting validity, comprise the pipeline to be detected of inner hollow, ball one and ball two is provided with in described pipeline to be detected, and the equal hollow in the inside of ball one and ball two, the outer installment of pipeline to be detected has control box, control box is connected with air pump, air pump is communicated with ball two with ball one simultaneously, between ball one and air pump, valve is provided with between ball two and air pump, and valve respectively with corresponding ball one and air pump, ball two is connected with air pump, pressure transducer is provided with in ball one and ball two, and pressure transducer is all connected with control box, pressure-measuring pipe is provided with between ball one and ball two, pressure-measuring pipe one end is arranged on pipeline external to be detected through the wall of pipeline to be detected, one end that pressure-measuring pipe is arranged on pipeline external to be detected is connected with U-gauge, gas tube is provided with between ball one and ball two, gas tube one end is connected with air pump through after pipeline to be detected, valve three is provided with between gas tube and air pump, valve San Tong method is connected with gas tube and air pump.
In sum, the invention has the beneficial effects as follows: this system utilizes the change of air pressure, the situation of pipeline wall can be detected exactly, operator can be judged accurately to the situation of pipeline, avoid occurring potential safety hazard, solving the validity that existing detecting instrument detects when detecting pipeline can not control, and its error is large, cause the actual conditions of pipeline to judge, there is the problem of potential safety hazard.
