For undated references, the latest edition of the referenced document applies (including any addenda/errata). For dated references, only the editi
42、on cited applies. However, not all documents listed may apply to your specific needs. The body of the standard should be referred to for how these documents are specifically applied.

44、 units (SI) and U.S. customary oilfield units. For the purposes of this document, the conversion between the systems is not exact and has been intentionally rounded to allow for ease of use in calibration and measurement. 3 Terms and Definitions For the purposes of this specification, the following
45、terms and definitions apply. 3.1 annulus Area between the casing and open hole or previously set casing. 3.2 autofill (auto-fill) A feature incorporated in the design of some float equipment that allows the flow check system(s) to be initially disengaged so fluid may pass in either direction when ru
46、nning a string of casing. This feature facilitates casing fill-up and may also be used for surge reduction. NOTE This action may reduce surge pressures in the well that may otherwise be present if float valves remained closed during running of the casing. 3.3 float equipment float equipment assembly
47、 Casing accessories that contain one or more check valves and become part of the lower section of a casing string for the purpose of preventing the reverse flow of cement once placed in a wellbore annulus. 2 API SPECIFICATION 10F 3.4 forward flow Fluid movement in the direction the valve is designed
48、 to open. 3.5 manufacturer The firm, company, or corporation responsible for the manufacturing and marking of the product to warrant that the product conforms to the specification. 3.6 product family Float equipment developed for different casing sizes that utilizes the same design and materials (i.
49、e. valve design, plug seats, sealant, and elastomeric materials, etc.). Product families are identified in order to qualify designs without the need to test float equipment for every casing size. 3.7 reverse flow Fluid movement in the direction the float equipment valve is designed to close. 4 Symbols and Abbreviations AF auto fill ASTM American Society for Testing and Materials D cumulative forward flow duration hours (see Table 1) EN European standard HT high temperature HP high pressure ID inside diameter ISO International Organization for Standardization LP low pressure NIST Natio
