caliper logging การใช้

• The application of intelligent ultrasonic distance - measuring transducer in calipers logging
• Based on the outcome of 40 - armed caliper log analysis , suggestions on casing failure well repairing has been put forward
• We can obtain the eccentric circle ' s center , maximum drift diameter and effective drift diameter by using this method and the data of multi armed caliper log
• In order to study the theory of casing damage and reduce the casing damage of oil - water wells , a new log analysis method of multi - armed caliper log is expounded
• Multi - arm caliper logging tool is mainly used for measuring inner diameter changes of the casings , provides evaluation data such as casing diameter changes , casing wall thickness , outer diameter variations of the casings , elliptic changes and equivalent damaging loading , etc
• The software of analysis method of multi - armed caliper log imaging has been developed , and the on - site applied results show that the software can get the casing maximum drift diameter and effective drift diameter and simultaneously give the caliper hoop extension graph and cross section graph in arbitrary depth which can diagnose the sort and degree of casing deformation
