Розширення технологічних можливостей та оцінювання енергоємності роботи неорієнтованих компоновок низу бурильної колони

Abstract

New and simple construction of special technical tool and mathematical model of nonoriented bottom drilling string assemblies on its base have been offered. This construction use to ensure design profile parameters during drilling slant portion of the deviated and horizontal well in condition of hole roundness loss. In base of analytical research have been specified that this technological solution allows to ensure required path and technical – economic performances well drilling with using assemblies with least number of support - centring elements in condition of caving.
