Description
Technical field
The utility model belongs to oil-gas field development and Porous Media mechanism field, is specifically related to the spontaneous in the same way imbibition instrument of a kind of fracturing liquid.
Background technology
At present at compact reservoir, in the research of the particularly saturating shale gas reservoir of low porosity and low permeability, evaluating the spontaneous imbibition intensity of reservoir rock is one of emphasis of research.First, because low permeability reservoir throat is tiny, many places are in micro-nano rank, and the spontaneous imbibition phenomena that capillary force causes is more more obvious than conventional reservoir, and the impact produced reservoir is larger.Secondly, the water-intake capacity of low permeability reservoir depends on the type of lithology, stratum and the artificial liquid injected, and needs to carry out large batch of self-priming experimental study compact reservoir and the interaction of manually injecting liquid.Meanwhile, the general nonuniformity of low permeability reservoir is comparatively strong, especially in shale gas drilling process, needs repeatedly to sample evaluation to the shale of Different Strata or same stratum diverse location.
Rock sample often directly soaks in a liquid by conventional self-priming evaluation method, all directions have liquid to enter, belong to reverse self-priming category, because different rock sample geometric configuration is different, thus when contrasting different rock sample, shape factor interference experiment result, has very large adverse effect to data processing.
Summary of the invention
A kind of technical matters to be solved in the utility model is to provide the spontaneous in the same way imbibition instrument of a kind of fracturing liquid, the quality relation over time of the fracturing liquid that the one side that this instrument can measure rock core sucks or other liquid to be evaluated, from the spontaneous imbibition phenomena of research, understand this rock sample rate of water absorption, capillary force and water absorbing capacitys etc.This apparatus structure is simple, easy and simple to handle, and maintenance is easily, practical.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The spontaneous in the same way imbibition instrument of a kind of fracturing liquid, its structure comprises fluid reservoir, tongs, rubber tube, glass tube, tank, hurricane globe, glass pipe clamp, frame, rock core fixator, container, rock core frame, strain gauge and data line, is characterized in that: be connected with glass tube by rubber tube bottom described fluid reservoir, and described tongs is on rubber tube, and described glass pipe clamp is fixedly clamped glass tube, described fluid reservoir, after being filled with liquid in the system that rubber tube and glass tube are formed, because atmospheric pressure effect ensures to have liquid in tank and liquid level is concordant with glass tube bottom, described tank and container form linker, and described hurricane globe covers rock core fixator, container, rock core frame and strain gauge, described rock core frame upper end connects rock core fixator, and lower end contacts with strain gauge, and described rock core fixator can clamp rock core and ensure that rock core bottom surface contacts with liquid level in container, described fluid reservoir, tank, glass pipe clamp, container and strain gauge are fixed in frame, and described strain gauge exports signal to computer by data line, complete the time dependent measuring process of quality rock core being sucked to liquid.
By such scheme, described data line can pass through RS232 serial ports connection data storer or computing machine, sends data to computing machine and carries out collecting and processing.
Design concept of the present utility model:
The system that the tank of the spontaneous in the same way imbibition instrument of a kind of fracturing liquid has fluid reservoir, rubber tube and glass tube to form, water is full of, when due to reasons such as evaporations, when liquid level is lower than glass tube lower end in tank in system, glass tube lower end exposes in atmosphere, now air enters system, and the liquid in fluid reservoir flows out, and tank liquid level can rise, when liquid level rises to glass tube lower end, the glass tube mouth of pipe is by water seal, and air no longer enters fluid reservoir, and liquid level no longer rises.Therefore ensure liquid level stabilizing by air pressure energy tank, and tank and container form linker, thus in container, liquid level can maintain the position of just contact rock core.When rock core absorbs water, the quality of the water of suction conducts on strain gauge by rock core frame, and thus strain gauge can monitor the quality of rock core water suction over time, completes the process that the spontaneous in the same way imbibition of rock core is measured.
The beneficial effects of the utility model:
Can be found out by above-mentioned principle design, the spontaneous in the same way imbibition instrument structure of a kind of fracturing liquid that the utility model provides is simple, easy and simple to handle, and maintenance is easily, practical.When using this device to carry out spontaneous imbibition experiment, the quality that rock core sucks liquid changes in time and can export computing machine to by signal output part, realizes automatic acquisition function; This experimental provision can ensure that liquid level contacts with rock core bottom surface all the time, does not worry liquid surface evaporation; After replacing different liquids (as deionized water, fracturing liquid, kerosene, quinane, variable concentrations salt solution), the evaluation to variable concentrations fracturing liquid water suction situation can be realized.
