The 12th Global Conference on Polymer and Composite Materials (PCM 2025)

Abstract: With the gradual depletion of shallow oil and gas resources, deep (>4,500m) and ultra-deep (>6,000m) oil and gas have become the main sources of oil and gas resources in China. With the advancement of technology, the drilling depth has been gradually increased. Two extra-deep wells with a design depth of over 10,000 m are being drilled in China. One of the wells has exceeded 10,000 m. However, the high temperature in the deep formation poses a great challenge to the temperature resistance of drilling fluids. Water-based drilling fluids (WBDF) are multistage dispersion systems of clay, weighting agent and a variety of chemical materials in water. Drilling fluid serves as “drilling blood” and plays a vital role in carrying and suspending drill cuttings, stabilizing wellbores, and lubricating and cooling drill bits during drilling-based engineering. Water-soluble polymers mainly regulate rheology and control filtration in drilling fluids, but their performance fails under high-temperature and high-salt conditions, which is a serious problem for drilling safety and efficiency. This presentation will focus on the topic of high temperature resistant polymers used in the drilling fluid. It will cover the technical challenges of deep well drilling, the challenges for polymers and the current status of research on high temperature resistant polymers. Finally, some research results on high temperature resistant polymers from our team will be presented.

Biography: Dr. Xianbin Huang is an associate professor and a graduate supervisor in the School of Petroleum Engineering at China University of Petroleum (East China). He graduated from China University of Petroleum (Beijing) in 2017, majoring in oil and gas well engineering. His research interests include drilling fluids, polymers for high-temperature resistant drilling fluids, and materials for wellbore stabilization. He actively participates in product industrialization and engineering practice. Several high-temperature-resistant materials were industrialized and field applied in the drilling engineering. He is the leader of two National Nature Science Foundation of China (NSFC) research projects and six industry projects. It is a great honor for him to participate in the research of key technologies for China's 10,000-meter deep wells. In 2022, he was honored as an Engineer of Excellence in Shandong Province, China. He is Youth Editorial Board Members for Petroleum Science and several Chinese academic journals.
