A finite element model of wellbore stability was proposed for a horizontal well, and drill-string friction and lateral collision in the process of rotary motion were taken into account. An unconfined compression test was used for model validation, th

Directional rotary steerable is one of the key components of modern intelligent drilling, and the analysis of force and deformation in bottom hole assembly is the key to control a well trajectory. Although the introduction of edge calculation will si

ABSTRACT: Lost circulation is a technical problem in drilling engineering, resulting in increased drilling cost and extended drilling cycle. Reservoir rocks in Block A of Shale Gas have the characteristics of low porosity and low permeability, strong

ABSTRACT: Due to the complex lithology and geological conditions of deep and ultra-deep formations, fractured formations with narrow safety mud weight window are often encountered during drilling, which is easy to cause lost circulation and gas kick.

Introduction: With the increasing drilling depth of shale formation, downhole collapse is a frequent occurrence, which often manifests as borehole wall caving. Methods: We used the deep shale of the Longmaxi Formation to conduct the mechanical loadin
