5.3 Testing of the logging instrument
The testing of the logging instrument is carried out through the surface instrument (CLS system), according to the calibration table in the logging program FSYS, CSYS, and the listed logging methods. The computer calls the corresponding calibration subroutines one by one to calibrate the logging instrument, so as to check the working performance of the logging instrument (mainly its linearity and stability). 5.3.1 Overview of the calibration principle.
The measured values ​​of the logging instrument (such as potential difference, count rate, etc.) cannot directly reflect the nature of the formation, that is, they are not equal to the engineering values ​​required for logging. There is a linear relationship between the low measurement value and the engineering value, and the relationship formula has the following general form: EM (S / K) +
Wherein E is the known engineering value of the scale: S - the measured value of the instrument scale:
K - the correction factor for the transmission of the logging data line: M - the multiplication factor:
A - the coefficient.
The instrument measures the scale, that is, the scale, and the measured value is processed by the computer and converted into the corresponding engineering value, thereby realizing the inspection and calibration of the instrument.
5.3.2 Scale calibration device. For the CNC measuring and instrument system, the device for scale calibration should be divided into three levels. 9
SY 5423—91
5.3,2.1 Level 1 environmental simulation test well (national standard). This is a test well made of AUSTIN chalk, INDIA~NA limestone, CARTHAGE marble sandstone and concave dolomite with known porosity values, internationally known as API test well. 5.3.2.2 Level 2 environmental simulation test well (industry standard). The data obtained from this test well is compared with the data of the API test well set at the national standard to establish a certain relationship between the two, which is used as a level 2 standard scale device. 5,3.2.3 Level 3 simulation scale calibrator (enterprise standard), mainly used for production inspection and verification. The instrument's calibration and response to the level 3 scale calibrator are compared with the instrument's response in the advanced test well to establish a certain relationship between them. This type of device is used to inspect the instrument during the production process and on-site use. The configuration of the level 3 scale calibrator is shown in the appendix. 5.3.3 General steps for calibration. The calibration of this standard is three-level. 5.3.3.1 Connect the lower instrument to be calibrated to the ground instrument system. 5.3.3,2 Place the corresponding calibrator at the specified position of the lower instrument. 5.3.3,3 Enter the CALB (calibration) command into the computer and run the calibration program. 5.3.3.4 Print out the calibration results.
