The work of preparing International Standards is normally carried out through ISO technical committees. Each member bod
19、y interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrote
20、chnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO
21、 documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held res

25、, under the general title Well integrity: Part 2: Well integrity for the operational phaseThe following parts are under preparation: Part 1: Life cycle governance manualvi ISO 2014 All rights reservedISO/TS 16530-2:2014(E)IntroductionThis Technical Specification has been developed by producing opera
26、ting companies for oil and gas, and is intended for use in the petroleum and natural gas industry worldwide. This Technical Specification is intended to give requirements and information to the Well Operator on managing well integrity for the operational phase. Furthermore, this Technical Specificat
27、ion addresses the minimum compliance requirements for the Well Operator, in order to claim conformity with this Technical Specification.It is necessary that users of this Technical Specification are aware that requirements above those outlined in this Technical Specification can be needed for indivi
28、dual applications. This Technical Specification is not intended to inhibit or replace legal requirements; it is in addition to the legal requirements; where there is a conflict the legal requirement always takes precedence. This can be particularly applicable where there is innovative or developing
29、technology, with changes in field or well design operating philosophy.This Technical Specification addresses the process of managing well integrity by assuring compliance to the specified operating limits for identified well types, that are defined based on exposure of risk to people, environment, a
30、ssets and reputation, supported by associated well maintenance/monitoring plans, technical reviews and management of change.The following terminology is used in this Technical Specification.a) The term “shall” or “must” denotes a minimum requirement in order to conform to this Technical Specificatio
31、n.b) The term “should” denotes a recommendation or that which is advised but not required in order to conform to this Technical Specification.c) The term “may” is used to indicate a course of action permissible within the limits of the document.d) The term “consider” is used to indicate a suggestion
32、 or to advise.e) The term “can” is used to express possibility or capability.

33、 of the document. Users should therefore consider printing this document using a colour printer.1 ScopeThis Technical Specification provides requirements and methods to the oil and gas industry to manage well integrity during the well operational phase.The operational phase is considered to extend f
34、rom handover of the well after construction, to handover prior to abandonment. This represents only the period during the life cycle of the well when it is being operated and is illustrated in Figure 1.The scope of the Technical Specification includes: A description of the processes required to asse
35、ss and manage risk within a defined framework. The risk assessment process also applies when deviating from this Technical Specification. The process of managing well integrity by operating wells in compliance with operating limits for all well types that are defined based on exposure of risk to peo
36、ple, environment, assets and reputation. The management of well integrity is supported by associated maintenance/monitoring plans, technical reviews and the management of change. The assessment of existing assets (wells / fields) in order to start the process of Well Integrity Management in accordan
37、ce with this technical specification. The handover process required when changing from one activity to another during the operational phase.The scope of the Technical Specification applies to all wells that are utilized by the oil and gas industry, regardless of their age, type or location.The scope
38、 of the Technical Specification does NOT apply to: The periods during well intervention or work-over activities but it DOES include the result of the intervention and any impact that this can have to the well envelope and the associated well barriers. The equipment that is required or used outside t
39、he well envelope for a well intervention such as wire-line or coiled tubing or a pumping package.TECHNICAL SPECIFICATION ISO/TS 16530-2:2014(E) ISO 2014 All rights reserved 1ISO/TS 16530-2:2014(E)WellPlanningWellConstructionWellHand-overWellOperationalPhaseWellInterventionor Workover WellHand-overWe
