1.1 Subject content
This standard specifies the technical requirements, test methods, inspection rules and marking, packaging and storage requirements for drilling fluid sand content measuring instrument. 1.2 Scope of application
This standard applies to drilling fluid sand content measuring instrument (hereinafter referred to as instrument). 2 Reference standards
ZBY002 Basic environmental conditions and test methods for transportation and storage of instruments and meters ZBY003 General technical conditions for packaging of instruments and meters 3 Technical requirements
3.1 Normal working conditions
a. Ambient temperature: 5～40℃;
b. Relative humidity: 5%～95%;
c. Atmospheric pressure: 86～108kPa
d. The ambient air does not contain media that corrode chromium, nickel plating, non-ferrous metals and their alloys. The nominal capacity of glass test tubes and their capacity tolerances 3.2

3.2.2The nominal capacity of drilling fluid volume is 30ml, and the capacity tolerance is ±2%. 3.2.3The nominal capacity of water volume is 100ml, and the capacity tolerance is ±1%. 3.3Appearance
Ugly: The glass test tube should be smooth, transparent, with clear scale, and no defects such as cracks and gaps. The screen of h200 days should be flat: there should be no damage, looseness, etc.: c. The inner wall of the funnel should be smooth: there should be no defects such as cracks and scratches. 3.4 Performance against transport environment
The instrument shall meet the requirements of ZBY002 under the conditions of transport packaging, including +55℃ for high temperature test, -40℃ for low temperature test, 95% for relative humidity (at 25℃), and 250mm for falling from the mountain. After the test, the instrument shall meet the requirements of Article 3.3 of this standard.
4 Test method
4.1 Test conditions
Temperature: 15～35℃ (the maximum allowable temperature change rate is 1℃/10min); a.
b. Relative humidity: 45%~75%;
c. Air pressure 86～106kPa.
4.2 Test equipment and materials
a. Burette: Class A. 1, 5, 10, 20ml each. b. Distilled water: 100ml or more.
4.3 The nominal capacity of the glass test tube and its capacity tolerance test adopts the injection comparison method. Use a clean, dry burette to draw different amounts of distilled water in turn and record the amount drawn: then inject it into the glass test tube, observe that the liquid level rises to the corresponding scale, stop injecting: calculate the difference between the actual injection amount and the nominal capacity, and the difference shall not exceed the provisions of Article 3.2.
4.4 Appearance inspection
The appearance and marking of the instrument shall meet the requirements of Article 3.3 and Article 6.1 by sensory inspection. 4.5 Anti-transport environment performance test
The test shall be carried out in accordance with the provisions of ZBY002. After the test, remove the packaging and check the requirements of Article 3.3 in accordance with the method of Article 4.4. 5 Inspection rules
5.1 Factory inspection
Each instrument shall be inspected by the technical inspection department of the manufacturer before it can be shipped out of the factory. The inspection of the instrument shall be carried out in accordance with the provisions of Table 2. Table 2

6.2 Packaging
The instrument for transportation in boxes shall be packed with the complete set of accessories specified in the instructions and in accordance with the provisions of ZBY003. The glass test tube shall be packed in shockproof packaging.
6.3 Storage
The instrument shall be stored in a ventilated room with an ambient temperature of 5-40℃ and a relative humidity of 10%-90%. The indoor air shall not contain harmful impurities that can corrode the instrument.
Additional instructions:
This standard was proposed by China National Petroleum Corporation. This standard is under the jurisdiction of the Petroleum Instruments and Meters Professional Standardization Committee of China National Petroleum Corporation. This standard was drafted by the Lanzhou Refining and Chemical Industry General Instruments of China Petrochemical Corporation, and the main drafters of this standard are Rong Cui and Ding Youwei. This standard refers to the American Petroleum Institute specification APIRP13B publication "Recommended Practice for Standard Procedures for Testing Drilling Fluids" (10th edition, June 1984). This standard is still valid after the review in 199, and the review results have been approved by the State Administration of Petroleum and Chemical Industry.
