20、)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a t

21、echnical 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 Electrotechnical Commission (IEC) on all matters

22、 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 documents should be noted. This docume

23、nt 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 responsible for identifying any or all such

28、aluation of suitability of threaded casing connections for service in intermediate or production casing strings of thermal recovery wells. The TWCCEP defines such wells as those with operating temperatures that cyclically vary between minimum values appreciably below 180C and maximum values that ran

29、ge from 180C to 350C, in which the casing string is cemented and the primary axial loading is strain-based.Throughout this document, a casing connection subject to evaluation is referred to as candidate connection. A candidate connection denotes a product with unique design features and production s

30、pecifications for size, weight, and component materials (including pin, box, and interfacial components).The TWCCEP assesses the candidate connections galling resistance, structural integrity and sealability under loads typical for connection assembly and thermal-well service. The TWCCEP does not ad

31、dress impacts of external pressure, incomplete lateral pipe support, rotational fatigue, formation-induced shear, or environmentally-induced corrosion or cracking.The TWCCEPs evaluation procedure includes analysis and full-scale testing. In the analysis, worst-case combinations of the connection geo

32、metry and material properties are determined and specifications for test specimens are derived. In the full-scale tests, those specimens are subjected to loading representative of thermal well operations. While the TWCCEP aims to enable a statistically significant full-scale test, it does not demand

33、 a rigorous check of a true statistical placement of the tested sample responses relative to field connection performance, and thus inherently assumes that the test specimens are representative of subsequent field connections. For this reason, only connections with the same design parameters as the

34、candidate connection should be considered representative of the connection assessed under this protocol.The extensive effort involved in replicating thermal well field conditions in a laboratory environment limits the extent of physical testing that can reasonably be undertaken in an evaluation prog

35、ram. This protocol balances technical rigor and practicality to provide a baseline level of confidence in the candidate connections performance. Connection users should consider the scope of this evaluation and appropriate additions to address operation-specific conditions. Successful field use of a

36、 connection meeting the requirements of this protocol does not preclude an operators need to employ appropriate product quality assurance measures and field operating practices.The TWCCEP is the culmination of a thorough review of factors contributing to performance of casing connections in thermal

37、well applications. This protocol has been developed using input from operators descriptions of field practices, manufacturers feedback on connection design and production, available literature, knowledge of past connection qualification programs, and additional analytical and experimental work perfo

38、rmed in support of the protocol development. The TWCCEP is intended to be maintained and refined as new findings surface.vi ISO 2013 All rights reservedCopyright British Standards Institution Provided by IHS under license with BSI - Uncontrolled Copy Not for ResaleNo reproduction or networking permi

39、tted without license from IHS-,-,-PD ISO/PAS 12835:2013Qualification of casing connections for thermal wells1 ScopeISO/PAS 12835 is intended for assessment of casing connections for those field applications in which the design of the casing-connection system is strain-based, and in which primary axi

40、al loading is on the casing-connection system driven by constrained thermal expansion, and in which that primary loading exceeds the casing-connection systems yield envelope. Consequently, ISO/PAS 12835 should be considered as a protocol that is complementary to ISO 13679, which applies to classic e

41、lastic-design applications.ISO/PAS 12835 describes the structure of the Thermal Well Casing Connection Evaluation Protocol (TWCCEP) and provides guidelines for its use by new or repeat TWCCEP users, whose familiarity with the TWCCEP provisions might vary. Clause 6 describes fundamental assumptions a

42、dopted in the T WCCEP.NOTE The term “user” refers to a party that uses the TWCCEP in a connection evaluation program. That party might or might not be the same party as a later user of the evaluated connection in a field application.2 Normative referencesThe following documents, in whole or in part,
