Annotation:

Primary opening of a productive formation is one of the most important stages of wells construction, on which its future productivity and service life depend. The main reason for the deterioration of the productive reservoir properties and the decrease of a well flow rate is insufficient accounting for the nature of the drilling fluid properties influence on productive reservoirs characteristics. The modern science and drilling practice developed a lot of methods have been developed for selecting the types (kinds) of drilling flushing fluids that are most suitable for specific drilling purposes, including the initial opening of productive horizons, but their use requires a lot of time and money for conducting expensive laboratory and field studies. The authors of the article propose a method for substantiating the choice of the most effective drilling fluid from the known alternative ones for the initial opening of the productive formation by the drilling rig at the Urengoy field using the hierarchy analysis method.
