This specification was developed by Daqing Oil Construction Design Institute based on the notice of China National Petroleum Corporation (92) 4 Youke No. 66 on "Design Specification for Oilfield Oil and Gas Gathering and Transportation SY 4-84".
This revision was made after soliciting opinions from various oilfield design units, higher education institutions and petroleum colleges on SYI4-84, and absorbing the scientific research results and design experience in oil and gas gathering and transportation of various oilfields in recent years. In the revision, not only the content structure of SY4-84 was partially modified, but also two new chapters were added, "Instruments and Blue Control Systems" and "Oil and Gas Gathering and Transportation of Special Oilfields". The original oil and gas gathering and transportation pipeline crude oil and oilfield gas wall were made into separate chapters, and the writing format was also adjusted. This specification is interpreted by Daqing Oilfield Construction Design and Research Institute. Address: Ranghulu Road, Daqing City, Heilongjiang Province; Postal Code: 163712
