SY/T 5414-2002
This standard is revised on the basis of SY5414-91 "Enclosed Coring.1.H" and SY/T6200-1996 "Directional Coring Tool".
The main differences between this standard and SY5414-91 and SY/T6200-1996 are as follows: 1 The name of the standard is changed to "Special Coring Tool". 2 In addition to the enclosed coring tool and directional coring tool proposed in SY5414-91 and SY/T6200-1996, pressure-maintaining coring tool, shape-maintaining coring tool, confidential coring tool and horizontal coring tool are added. 3 The model representation method of coring tool is redefined. 4 Add a chapter on "Terms and Definitions".
Through revision, this standard will be more systematic and complete, and will effectively regulate the manufacture and inspection of coring tools. From the date of implementation, this standard will replace SY5414-91 and SY/T6200-1996. This standard was proposed and assigned by the National Technical Committee for Standardization of Petroleum Drilling and Production Equipment and Tools. Drafting unit of this standard: Drilling Technology Research Institute of Shengli Petroleum Administration Bureau. Participating units of this standard: Drilling Technology Research Institute of Sichuan Petroleum Administration Bureau, Drilling Sichuan Research Institute of Daqing Petroleum Administration Bureau: Drafters of this standard: Yang Zhengkun, Xu Junliang, Yang Mingjin, Bo Wanshun, Yang Yongxiang. 1 Scope
