SY5436-1998
This standard is a revision of SY5436-92 "Storage, transportation and use of explosives for petroleum perforating and sidewall coring". With the continuous development of oil and gas exploration and development, considering the continuous improvement of the use technology of explosives and the continuous expansion of the use field, it is necessary to revise SY 5436-92. This time, the focus is on the revision of SY5436-92 from the perspective of safe use, but it is impossible to include all the details of the relevant regulations and operating methods, and it cannot replace the technical operating standards of this industry. This standard is proposed by the Petroleum Industry Safety Professional Standardization Technical Committee and is under the jurisdiction of the North China Petroleum Administration Well Logging Company. The main drafters of this standard are Zhou Yuping, Fan Wei, Yin Guihua. This standard was first issued in April 1992.
