Research and Evaluation of Efficient Drilling Speedup Supporting Technologies and Cementing Processes for Ultra-deep Wells

Abstract

This paper conducts research and evaluation on the supporting technology for efficient drilling and acceleration in ultra-deep wells, as well as cementing processes. By reviewing the latest research achievements and technological advancements both domestically and internationally, various technical means related to drilling engineering design, fluid systems, equipment, and operation management are summarized. The applicability and benefits of different techniques are deeply studied through the analysis of multiple practical case studies. Additionally, a comparative analysis of various cementing processes used in ultra-deep well development is conducted to assess their strengths, weaknesses, and applicability. Finally, optimization recommendations for efficient drilling and acceleration technology, as well as cementing processes in ultra-deep wells, are proposed, along with future prospects for the development of ultra-deep well drilling technology. This study provides a scientific basis and technical support for the efficient development of ultra-deep oil and gas resources.
