Abstract
A quantitative scoring and optimization method of a drilling and completion loss-control material includes: extracting key performance parameters of drilling and completion loss-control materials in loss-circulation zone, sequencing the key performance parameters according to their importance; performing weight calculation on the key performance parameters of the loss-control material by an analytic hierarchy process; determining scores of the key performance parameters of conventional loss-control materials according to an experimental evaluation table of the performance parameters of the loss-control materials; calculating comprehensive scores of all loss-control materials and performing optimal selection on the loss-control materials according to the comprehensive scores. The present disclosure provides a quantitative evaluation table of performance parameters of the loss-control materials, and an optimal selection method of the loss-control materials for different loss-control formations according to the analytic hierarchy process.
