STUDY ON SOFTWARE FOR CASING LOAD ANALYSIS AND STRENGTH DESIGN

Based on the actual requirements of drilling technology progress and current oil and gas exploration and development, the number of deep well, ultra-deep well and directional well increases continuously. In order to meet these requirements, this paper, on the basis of casing strength design software for normal straight well and directional well, studies all-sidedly characteristics of casing load for both deep well and ultra-deep well, and combines the conventional casing design method, the triaxial stress design method and the casing optimization method. The casing strength design software is developed by applying the database system. The software possesses multifunction in casing optimization design for normal well, deep well, ultra-deep well and directional well. The software will be widely used since its input-output interface supports any unit system.
