Technical Problems and Countermeasures for the Drilling Operation in Complex Formations of Scientific Deep Drilling Projects
Abstract:This article introduces the difficulties and technical problems encountered in the drilling operation in complex formation of scientific deep drilling projects. The main technical problems are broken formation drilling and strong shrinkage formation drilling. Technical measures for resolving the problems, referring to core drilling technologies, drill rig, drilling mud system and special drilling and cementing technologies used for strong shrinkage formation, are discussed.
