TUBING ELONGATION CORRECTION SYSTEM AND METHODS

摘要

A surface processor (26) uses an environmental profile to determine the sub- surface length of tubing (34) disposed in a well bore. Information relating to tubing properties is stored in a memory module of the surface processor (26) . The environmental profile includes data relating to well bore ambient conditions and the operating parameters of well equipment. Surface processor (26) calculates the tubing elongation or length reduction corresponding to t he environmental profile. Surface processor (26) may repeat this process to develop a measured depth chart for a well. Logging operations performed in conjunction with the sub-surface length calculations allows formation data t o be associated with the measured depth chart.
