英语翻译
IADC Well Classification System for Underbalanced Operations and Managed Pressure Drilling The purpose of the IADC Well Classification System is to describe the overall risk,application category and fluid system used in underbalanced operations (UBO) and managed pressure drilling (MPD).Wells are classified according to:
.Risk Level (0 to 5)
.Application Category (A,B or C)
.Fluid System (1 to 5).
This classification system provides a framework for defining minimum equipment
requirements,specialized procedures,and safety management practices.For further
information refer to the IADC UBO HSE Planning Guidelines and other related documents.
Risk Levels
Generally,risk increases with operational complexity and potential well productivity.The
examples provided are for guidance only.
Level 0 – Performance enhancement only; no hydrocarbon containing zones.
.Air drilling for ROP enhancement
Level 1 – Well incapable of natural flow to surface.Well is inherently stable and is a low level risk from a well control point of view.
.Sub-normally pressured oil wells
Level 2 – Well is capable of natural flow to surface,but can be controlled using conventional well kill methods.Catastrophic equipment failure may have limited consequences.
.Abnormally-pressured water zones
.Low flow rate oil or gas wells
.Depleted gas wells
Level 3 – Geothermal and non-hydrocarbon bearing formations.Maximum anticipated shut-in pressure (MASP) is less than UBO/MPD equipment pressure rating.
.Includes geothermal wells with H2S present
Level 4 – Hydrocarbon bearing formation.Maximum anticipated shut-in pressure is less than UBO/MPD equipment operating pressure rating.Catastrophic equipment failure will likely have immediate serious consequences.
.High pressure and/or high flow potential reservoir
.Sour oil and gas wells
.Offshore environments
.Simultaneous drilling and production operations
