Technical field
The utility model relates to a kind of rock salt and makes the chamber test unit, relates in particular to a kind of test unit that utilizes ultrasonic listening to contain sandwich type salt cavity expansion process.
Background technology
Relative other deposit mode, rock salt underground oil and gas warehouse have safety, economic characteristics, but external rock salt underground storage has still the time accident that (like hydrocarbon seepage, dissolve chamber inefficacy, subsidence etc.) takes place.At present external underground rock salt bank is nearly all built in the huge thick salt dome, and China can build the rock salt of underground storage and is stratiform rock salt, has thin thickness, interlayer is many, grade is low, the characteristics of buried depth big (it is 1000m that the Hubei cloud is answered the rock stratum buried depth).The underground rock salt bank construction of China difficulty is bigger by contrast, operation risk is higher.Present domestic rock salt is made the chamber cost more than tens million of units, in case make chamber failure, the economic loss that causes is huge, also can produce a series of geologic hazard, so be necessary to carry out the relevant chamber experimental study of making.The research that contains interlayer salt karst chamber cavity geometry control technology is the basis of rock salt bank shape control; The shape of control rock salt underground storage is the minimizing accident and avoids one of main means of operational risk that the bank with ideal form has better stability, leakproofness and longer serviceable life.During test since rock salt (or large scale type salt) make in the process of chamber cavity geometry can not tracking and monitoring, cause can not quantitative test making the influence of chamber technology cavity geometry control, can't obtain accurately, reliable, the chamber scheme of making optimized.Can make whole various influences of making chamber technology of making the chamber process in the process of chamber by tracking and monitoring so must find a kind of method and device to the cavity geometry expansion.
The utility model patent content
To weak point of the prior art; The utility model provides a kind of test unit that utilizes ultrasonic listening to contain sandwich type salt cavity expansion process; But this test unit tracking and monitoring is respectively made chamber stage cavity geometry expansion process, comes effective analysis respectively to make the influence of chamber technological parameter to cavity geometry control through the Changing Pattern of making cavity shape.
The ultrasonic listening that utilizes that the utility model provides contains the test unit of sandwich type salt cavity expansion process, comprises sandwich type salt cavity test specimen, makes chamber protector string, ultrasonic transducer and IES data analyzer; A said end of making the chamber protector string stretches in the cavity in the sandwich type salt cavity test specimen, and the transmitting probe of said ultrasonic transducer and receiving transducer also are emitted on the lateral surface of sandwich type salt cavity test specimen, and ultrasonic transducer is connected with the IES data analyzer.
As a kind of preferred version of the utility model, be laid with check point on the outer wall of said sandwich type salt cavity test specimen, the transmitting probe of said ultrasonic transducer and receiving transducer are placed on the check point place on the outer wall of sandwich type salt cavity test specimen.
The beneficial effect of the utility model is: open ultrasonic transducer detection mensuration ripple and calculate the thickness of making the chamber stage arbitrarily in the time that the wall of sandwich type salt cavity test specimen is propagated; Rock salt chamber wall thickness through each check point of statistical fit; Be aided with the shape that three-dimensional drawing software just can draw cavity again; The realization tracking and monitoring is respectively made chamber stage cavity geometry expansion process, comes effective analysis respectively to make the influence of chamber technological parameter to cavity geometry control through the Changing Pattern of making cavity shape.
