Description
Technical field:
The present invention relates to experimental facilities, further say to relate to a kind of voltage-controlled living hydrocarbon simulating hydrocarbons expulsion experiment device of solid-fluid coupling that is applied to hydrocarbon source rock.
Background technology:
Generation and expulsion modeling experiment is to reappear underground livings hydrocarbon and hydrocarbon expulsion process under indoor conditions, can study the row's of giving birth to hydrocarbon Evolution of hydrocarbon source rock by simulated experiment, obtains the row's of giving birth to hydrocarbon quantitative parameter.Only have as far as possible simulate formation condition, experimental result could reflect objective circumstances more exactly.The influence factor of the row's of giving birth to hydrocarbon is complicated under the geological conditions, comprises temperature, lithostatic pressure, fluid pressure, fluid composition, inorganic mineral character etc.Adopted many methods to carry out relevant simulation, and the pressure condition of as far as possible realizing ideal, the actual environment of arranging hydrocarbon with life can be close, and the result who obtains gets over reliably." the underdone oily genesis mechanism simulation experiment study of brackish water lacustrine facies " introduced such as " Chinese science " 4 phases of 44 volumes in 1999 namely is the living hydrocarbon simulated experiment technology that has adopted under the compacting condition, obtained preferably effect.The technology that No. 012642606 patent is introduced also similarly.But most of of this sort technology can only be controlled the vertical pressure of covering now, can not control simultaneously the fluid pressure in the hole, also therefore can not control state and the character of fluid.Chief reason is control device that these experiments lack cover fluid pressures, and controls simultaneously vertical solids pressure and pore fluid pressure has certain difficulty.If can not reach this condition, then very difficult effectively simulate formation overpressure fluid can not be simulated the chemical property of fluid to giving birth to the impact of hydrocarbon to the effect of the row's of giving birth to hydrocarbon.
Summary of the invention:
Purpose of the present invention is intended to overcome the deficiencies in the prior art, and a kind of voltage-controlled generation and expulsion modeling experimental provision of solid-fluid coupling that can control simultaneously vertical solids pressure and pore fluid pressure in the generation and expulsion modeling experiment is provided.
Purpose of the present invention can be achieved by the following technical measures:
The autoclave of this device is made of the upper and lower autoclave main body that is connected with respectively autoclave top cover and autoclave base, axially there is vertical pressured column at the autoclave middle part, autoclave and in the pressure duct that is provided with between the high-pressure buffer of piston be connected with triple valve, high-pressure buffer is connected with fluid pressure control pump pipeline, is connected with the two-port valve of belt switch on the connecting line of triple valve and collector.
Purpose of the present invention also can be achieved by the following technical measures:
The stainless steel piston is arranged in the described high-pressure buffer, distilled water and the simulated formation fluid of controlled pressure arranged in the chamber, stainless steel piston both sides; Upper connecting hole on the described autoclave and lower connecting hole are communicated with by pressure piping, and pressure piping is communicated with triple valve.
Autoclave of the present invention adopts special moving/the static seal technology, and fluid does not leak under the high pressure conditions.The autoclave main body is the key reaction district of the row's of giving birth to hydrocarbon, can bear vertical solids pressure and inner fluid pressure thereof.Solids pressure is applied by hydraulic pump, by the plunger transmission.Autoclave all has up and down fluid extraction/hand-hole to be in communication with the outside.Autoclave is communicated with triple valve by its connecting hole, the triple valve other end links to each other with high-pressure buffer so that controlled pressure, the 3rd end of triple valve links to each other in order to take out fluid sample with the two-port valve of belt switch, high-pressure buffer links to each other with the fluid pressure control pump, final by fluid pressure control pump control fluid pressure, the left end of high-pressure buffer is the simulated formation fluid, right-hand member is the distilled water of controlled pressure, the two is not mixed mutually mutually, but pressure is consistent, and lateral pressure applies by vertical pressured column.
Upper connecting hole on the autoclave and lower connecting hole are communicated with by pressure piping, the high pressure line of connection and in the pipeline that is provided with between the high-pressure buffer of piston be connected with triple valve, high-pressure buffer is connected with fluid pressure control pump pipeline.The stainless steel piston is arranged in the middle of the buffer, can move with balanced fluid pressure, separate simultaneously outer fluid stablizing with the fluid properties in the maintenance autoclave in the autoclave, come controlled pressure by fluid pressure control pump and high-pressure buffer, cover in the situation of solids pressure in control, further control pore fluid pressure and character.The present invention better simulate formation gives birth to burden pressure and the fluid pressure environment of arranging hydrocarbon, improves the control device of fluid in the generation and expulsion modeling experiment, and the row's of giving birth to hydrocarbon environment of simulate formation has reached better experiment effect more approx.
