This standard is a revision of the "Static penetration test technical specification" $Y58--89 according to the requirements of the document No. 42 of the China National Petroleum Corporation (97).
This standard is divided into 718 sections and 93 articles. The main contents include general principles, terms, symbols, equipment, probe calibration, field testing, data compilation and analysis and application of test results.
The contents to be revised in this revision are:
1 The name of the standard is modified according to the format requirements of the document No. 1996!626 of the Ministry of Construction: the prefix, terms and symbols are added: 2 2.0.4, 3.0.7, 3.0.9, 4.0.6, 4.0.7, 4.0.14 and Appendix 4 of SYJ 58--89 are cancelled: 3 The chapters on probe, analysis of test results and lung cochlea are added: 4 The contents of the chapters on equipment, on-site testing and data compilation are supplemented and improved: The editing unit of this standard is: Jianghan Petroleum Administration Bureau Survey and Design Institute, and the drafters of this standard are Ma Yanjun, Fumin, Yi Huihan and Lei Zhiming.
This standard is interpreted by Jianghan Petroleum Administration Bureau Survey and Design Institute, and this standard was first issued in March 1989. 1.0.1 This standard is specially formulated to unify the technical requirements of static penetration testing for rock survey in the oil and gas industry, improve the technology and work quality of static penetration testing, and provide a basis for inspection, on-site testing, data compilation, application of results and acceptance of results. 1.0.2 This standard is applicable to static penetration testing of clay, powder, sand, layers containing a small amount of crushed stone and the upper layer of plain fill soil. 1.0.3 In areas where there is experience in the use of static penetration testing, static penetration testing can be used alone according to the nature and scale of the project. When investigating in important engineering sites or areas where there is a lack of experience in static penetration testing, as well as in special areas such as collapsible soil, soil with impermeable soil, and expansive soil, it should be used in conjunction with sampling tests or other exploration procedures. 10.4 In addition to complying with this standard, static penetration testing technology should also comply with the provisions of the current national mandatory standards.
This standard refers to the following standards:
