Utilize Diagenesis simulation experimental apparatus of the present invention to provide more to approach natural simulated conditions carbonate retrograde solubility is simulated.In order to verify carbonate retrograde solubility, the present embodiment utilizes the Diagenesis simulation experimental apparatus shown in Figure 12, the temperature of setting reactor R1 is 200 DEG C, the temperature of reactor R2 is 50 DEG C, reaction solution is pure water, rock sample adopts respectively the particle of kalzit and soda feldspar, and particle size range is 2.8～4.0mm.First, control valve, guarantees that reactor R1 and reactor R2 are connected state.Open reactor R1 and R2, put into respectively kalzit and the soda feldspar particulate samples of equivalent, then sealed reactor R1 and R2.Start highly pressurised liquid ram pump F2, pure water, with in 0.1ml/min flow velocity injected system, after system outlet flows out water, is regulated to buffer brake controller P, the working pressure of determining current system is 25MPa.The experimental temperature of setting primary heater W1 and reactor R1 is 200 DEG C, and the experimental temperature of thermode W2 and reactor 2 is 50 DEG C.According to the calculating of solution flow rate and reactor volume size, in sustained response, after 48 hours, in reactor R1 and reactor R2, solution reaches respectively metastable state.Now, open valve V4, in reactor R1, generating liquid 001 can flow in stopple coupon Q1 under high drive, valve-off V4 after having sampled.Complete after the online sampling of High Temperature High Pressure solution for reactor R1, utilize conventional analysis equipment to carry out composition and content analysis to solution in stopple coupon Q1.Open valve V11, the interior generation liquid 002 of reactor 2 can flow in stopple coupon Q2 under high drive, valve-off V11 after having sampled.Complete after the online sampling of High Temperature High Pressure solution for reactor 2, utilize conventional analysis equipment to carry out composition and content analysis to solution in stopple coupon Q2.
According to carbonate retrograde solubility, can estimate that calcium ion in reaction solution 002 is by the content higher than in reaction solution 001, the sodion in reaction solution 002 by lower than or be equivalent to the content in reaction solution 001.By this experiment, can verify that carbonate retrograde solubility, explaining in Clastic Stratum of Country Rocks, exists the effect of this geological phenomenon of the secondary hole of the aluminosilicate such as carbonate cements and feldspar corrosion in a large number.
Diagenesis simulation experimental apparatus provided by the invention, comprise two above heat resisting and pressure resisting reactors that are interconnected by pipeline and valve, can simulate different stratum buring environments, complete in different temperature and pressure conditions and keep more than two stage water rock course of reaction in fluid continuous flow situation, realize continuous multistage water rock reaction experiment simulation, this will contribute to make in the experimental phase fluid chemistry character closer to natural actual conditions.In the experimentation of multistage continuous flow, by copying temperature, pressure, fluid chemistry character, mineral composition and the flow performance of different phase in diagenesis mechanism, can effectively simulate due to Diagn such as corrosion that basin lifting causes temperature in actual formation, pressure, fluid properties to change to cause, cementing, explanations; Diagenesis simulation experimental apparatus of the present invention have the fast and temperature of high temperature high voltage resistant, heating evenly, stable pressurization, high-temperature high-pressure in-situ analytical solution composition, High Temperature High Pressure sample online, High Temperature High Pressure detects the functions such as permeability online, not only can simulate open flow system but also can simulate the water rock reaction under static closed system, especially can simulate more truly by the experiment of multistage continuous stream the Diagn that actual formation occurs; Again in conjunction with High Temperature High Pressure solution compolision original position analytical technology and the online sampling technique of High Temperature High Pressure solution, can analyze the fluid properties of each elementary reaction generation liquid, so just realize the experimental simulation to Petrogenetic Model, contributed to provide Petrogenetic Model more accurately; Utilize core permeability evolution on-line measuring device, can effectively simulate cover press and hot conditions under water rock between true core and fluid react, and can detect in real time, online the permeability value of rock core, realize the transformation efficiency of quantitative description fluid to rock core internal void.
According to Diagn simulation experiment study content, experiment can be both cylindrical shape with rock sample, also graininess.Testing required high pressure is from fluid reservoir, to be extracted solution and compressed institute by highly pressurised liquid ram pump to be produced, test required high temperature and be that high heat that electric heating cover that the uniform winding resistance wire by being wrapped in reactor outside makes produces realizes, because resistance wire is uniform winding, so temperature of reaction kettle is uniform.The temperature of whole device and pressure control both can have been passed through the control panel manual adjustments of switch board, can select again computer operation.The inlet end of reactor connects primary heater or thermode, for heating in advance or cooling reacting fluid, can reduce and even avoid the temperature difference of fluid in reactor.Valve is equipped with at the outlet of reactor and entrance two ends, and by control valve, reactor can carry out static capping system also can provide open flow reaction system.The endpiece of reactor connects the online sampler of High Temperature High Pressure, and this device can obtain the generation liquid in reactor in course of reaction, for composition and content analysis; The endpiece of reactor also connects in-situ observation pond, fibre-optical probe is connected in-situ observation pond with spectrometer, in multistage continuous flow reaction system, the generation liquid of the reactor in-situ observation pond of can flowing through, now, utilize spectrometer can under high-temperature high-pressure in-situ condition, analyze the composition and the content that in observation pond, generate liquid.When fluid is through in core holding unit when rock core cylinder sample, core holding unit two ends can produce pressure differential, and the differential pressure detector that this value can be equipped with by core holding unit two ends records, permeability that can computing rock sample by this value.Core holding unit confined pressure is produced by solution in the tank that boosts of manual pump compression clamper.In addition, connected mode between multiple reactors of diagenetic process analogue experiment installation and between reactor and core holding unit has adopted the serial/parallel design that is connected, under series connection, Diagenesis simulation experimental apparatus can provide multistage continuous flow experimental situation, carries out multistage water rock reaction experiment simulation; Under state in parallel, reactor or core holding unit independent operating separately, provides single stage water rock reaction experiment simulation, thereby increases work efficiency.And reactor, valve, pipeline all adopt inconel625 alloy material to make, this just guarantees that whole device can high temperature resistant, high pressure resistant and strong alkali-acid resistance corrosion.
