Scope
SY/T 5623-2009 is the English-translated version of 地层压力预(监)测方法.
SY/T 5623-2009 — This standard specifies the onshore and offshore oil and gas drilling in the sand, shale formation pore pressure, fracture pressure pre (monitoring) measurement method.
Pore ??pressure used in the pre-(monitoring) test theory is based on the extent of the role of shale undercompaction pore fluid caused by abnormally high pressure and mudstone undercompaction on the mechanism corresponding to the extent applicable to the sand-shale sequence profiles initial development of oil and gas wells and vertical wells formation pressure prediction and monitoring, using dc index monitoring pore pressure and the use of PDC bits, you can refer to the use of this standard.
