Examining system.
Background technique
During oil exploitation, to improve yield, technological means can be taken to carry out displacement of reservoir oil operation oilbearing stratum, wherein
Using high-pressure delivery pipeline to oil reservoir continuous infusion CO2It is gradually to tend to a kind of mature technology.
Under normal circumstances, CO2Conveyance conduit is squeezed by high pressure (10-20Mpa) pump and is delivered to decanting point, this section of distance conveying
Pipeline can continuously be in the operating status (such as 19Mpa operation) of high pressure, the CO in pipeline2It is in liquid under normal circumstances, this
The high-voltage operation pipeline of sample can seriously affect the recovery ratio of crude oil, especially emphasis once leakage accident, which occurs, to be found in time
It wants, is danger close around leakage point, first is that high-pressure liquid CO2Under instantaneous loss of pressure, ramp case, it can generate powerful
Air column, the impact of this air column once encounters organism, can be punctured moment, seriously threaten life；Second is that leaking out
CO2It can be spread on leakage point periphery rapidly, the CO of nucleus2Concentration will lead to human or animal's asphyxia.

Property, to reduce sensitivity, cause Small leak slow in reacting；Above situation is for traditional leakage monitoring method, either
(signal transmission speed is unstable), which is all difficult effectively to realize, on from the algorithm of the acquisition precision of signal and software monitors；Have again just
It is CO2Conveying be all from pumping plant directly to decanting point, the not instead of hair of conventional pipelines conveying, debit's formula are directly injected into ground
Lower oil reservoir, so not being equipped with measuring equipment usually in decanting point, it is complete only to install a measuring equipment in the exit of pumping plant
The injection rate of Cheng Yitian counts, and decanting point process flow does not also have the condition of installation measuring equipment, so traditional conveying
Pipeline first, last point throughput rate balancing method is not available yet.
