25、zation 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 technical committee has been establishe

26、d 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 of electrotechnical standardization.

27、International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Pub

28、lication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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 patent

ISO 13503-5 was prepared by Technical Committee ISO/TC 67, Materials. equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 3, Drilling and completion fluids, and well cements.

32、rences 2 to 15. The tests and test apparatus herein have been developed to establish standard procedures and conditions for use in evaluating the long-term conductivity of various hydraulic fracture proppant materials under laboratory conditions. This procedure enables users to compare the conductiv

33、ity characteristics under the specifically described test conditions. The test results can aid users in comparing proppant materials for use in hydraulic fracturing operations. The procedures presented in this publication are not intended to inhibit the development of new technology, materials impro

This part of ISO 13503 may be used by anyone desiring to do so. Every effort has been made by ISO and API to ensure the accuracy and reliabili

37、ng-term conductivity of proppants CAUTION The testing procedures in this part of ISO 13503 are not designed to provide absolute values of proppant conductivity under downhole reservoir conditions. Long-term test data have shown that time, elevated temperatures, fracturing fluid residues, cyclic stre

38、ss loading, embedment, formation fines and other factors further reduce fracture proppant pack conductivity. Also, this reference test is designed to measure only the frictional energy losses corresponding to laminar flow within a pack. It is recognized that fluid velocity within an actual fracture

39、can be significantly higher than in these laboratory tests, and can be dominated by inertial effects. 1 Scope This part of ISO 13503 provides standard testing procedures for evaluating proppants used in hydraulic fracturing and gravel-packing operations. NOTE The “proppants” mentioned henceforth in

40、this part of ISO 13503 refer to sand, ceramic media, resin-coated proppants, gravel packing media, and other materials used for hydraulic fracturing and gravel-packing operations. The objective of this part of ISO 13503 is to provide consistent methodology for testing performed on hydraulic-fracturi

41、ng and/or gravel-packing proppants. It is not intended for use in obtaining absolute values of proppant pack conductivities under downhole reservoir conditions. 2 Normative reference The following referenced document is indispensable for the application of this document.

The effects of fines, formation hardness, resident fluids, time, and/or other factors are beyond the scope of this procedure. 5.2 Discussion In this part of ISO 13503 procedure, a closure stress is applied across a test unit for 50 h 2 h to allow the proppant sample bed to reach a semi-ste

48、ady state condition. As the fluid is forced through the proppant bed, the proppant pack width, differential pressure, temperature and flow rates are measured at each stress level. Proppant pack permeability and conductivity are calculated. Multiple flow rates are used to verify the performance of th

49、e transducers, and to determine darcy flow regime at each stress; an average of the data at these flow rates is reported. A minimum pressure drop of 0,01 kPa (0,002 0 psi) is recommended; otherwise, flow rates shall be increased. At stipulated flow rates and temperature conditions, no appreciable non-darcy flow or inertial effects are encountered. After completing the rates at a closure stress level in all cells, the closure stress is increased to a new level; 50 h 2 h is allowed for the proppant bed to reach a semi-stea
