Experimental Research On The XAN-JR Latex Cementing Fluid System

Latex cement slurry has better channeling prevention and toughening crack resistanceperformance. But in the practice of complex wells cementing and gas storage well cementing,we found that the cementing of latex cement slurry formed the integrity and durability of thecement ring still can not meet the needs of complex wells and gas storage. This paper firstlystudies a new type of cementing self-healing agent XJKZ-WOT6, filters agents Of latexcement slurry and works out a XAN-JR latex cementing system which has the performance ofself-healing agent developing through the orthogonal test.The results show that, the study ofXAN-JR latex cementing fluid system, not only has basic performance of latex cement slurrysystem, but also has good system stability, good self-healing function to the formation ofmicro-cracks cementing ring, and the enhancement of anti-injury performance of latex cementslurry system. Thus ensuring the integrity and durability of the oil and gas well cementing andgas storage cementing ring. This study on the development of oil and gas well cementingself-healing technology can improve the performance of latex cement slurry, ensure thequality of well cementing and improve the safety and economy of the development of oil andgas wells. It has a certain engineering value.
