Description
Technical field
The invention belongs to the tracer agent measuring karst aquifer underground water, particularly relate to a kind of tracer agent for underground hydrological detection and its preparation method and application.
Background technology
The karstic ground water circulation system, except affecting by geographic and geomorphic conditions, also affects, because the migration of karsts developing area and karstic ground water generally all has obvious nonuniformity by architectonic.Except common karst pore character, the pipeline mediums such as the solution cavity of growing in addition and crack, Karst Features is different, seepage and EXIT POINT more, water conservancy slope change is large, each waterpower flow velocity has obvious otherness, defines complicated hydraulically plastidome, and the distribution of the memory space of its underground water, karst water conservation Rotating fields, underground water tendency and underground water pinniform is difficult to analyze to be understood.Dust trajectory research is dominated in order to carry out karst in karst area, the space distribution situation of the solute transfer main channel of the pipeline medium to karstic ground water motion, passage and correspondence is needed to investigate, adopt the method for on-the-spot tracer test on the spot, Groundwater In The Karst Area mechanical relationship is studied, determine the major flow of underground water to, provide foundation for investigating the pollution condition of underground water.
Tracer agent is utilized to be one of on-the-spot test technology to karstic ground water dust trajectory tracer technique, its principle injects tracer agent from injection well head, by sampling standard prospect pit sampling around, monitoring tracer agent situation of change, sample is analyzed, draw tracer agent change curve, by related software matching, the connection situation of water system in reflection Karst Groundwater Systems, grasp the direction of propulsion of karstic ground water, actuating speed, in reservoir bed nonuniformity, in the distribution situation of saturated zone, thus instruct the mining of groundwater design of geology karst region, the geology karst region groundwater development later stage adjusts, the pollution condition of underground water.
When adding a certain amount of tracer agent in injecting well, tracer agent can be dissolved in the water, form one section of zone of enrichment, by the concentration curve of tracer agent in monitoring prospect pit around, appliance computer numerical analysis means, just can feed back the flow performance of karst aquifer underground water characterisitic parameter and tracer agent.
In prior art, the most frequently used tracer agent mainly contains chemical tracer and coordination rope tracer agent.Although these tracer techniques are widely used in territory, each geology karst region, also there is shortcoming in various degree: chemical tracer consumption is usually all comparatively large, and cost is high, metrical error is larger; Isotopic tracer then requires it must is professional construction personnel, and application specific equipment Inspection, pollutes water environment, is unfavorable for large-scale promotion application.
Chinese patent CN1699998A disclose a kind of for the constant material tracer agent in geology karst area survey process and this tracer agent the using method in deposit dynamic monitoring, wherein provided tracer agent is unit of bright-coloured system rope, is specially one or more in the elements such as lanthanum, cerium, Praseodymium, rubidium; The use of these elements often coordinates complexing agent, as: ethylenediamine tetraacetic acid, EDTA, ethylenediamine form complex compound jointly use through ethyl triacetic acid, diethylenetriamine pentaacetic acid, nitrilotriacetic acids, it in use also exists certain deficiency, main manifestations is that tracer agent major part heat resistance is poor, these tracer agents can not bear the high salinity of geology, under high salinity condition, can there is chemical reaction in tracer agent, loses the function of spike.In addition, these tracer analysis precise decreasing under high salinity media, even cause analysis result to lose efficacy.
Chinese patent CN98114214.1 discloses a kind of inter-well tracing determination technology using chemical tracer, chemical tracer monitoring technology, in the region practical application of geology karst, also exists poor chemical stability, heat-resisting ability is not enough, resistance to high salinity is low, accuracy of detection is unstable shortcoming.
