Research on the Physical Strength of Surface Conductor Soil Under Deep Jet Drilling
The installation of a surface conductor in deepwater jet drilling is crucial for offshore oil and gas development. This study investigates the interaction between the surface conductor and subsea soil during injection drilling. A simplified model using ABAQUS finite element software analyzes the damage effect of the water jet on the soil and simulates the mechanism of soil body damage under different parameters. The mechanical behavior of the soil and conductor during installation is examined, and the load-bearing characteristics of the soil are analyzed. Sensitivity analysis of factors such as injection displacement and bit extension reveals their significant influence on conductor installation. The findings provide insights into the drilling process and contribute to ensuring the stability of the wellhead in deepwater drilling operations.
期刊介绍：
Chemistry and Technology of Fuels and Oils publishes reports on improvements in the processing of petroleum and natural gas and cracking and refining techniques for the production of high-quality fuels, oils, greases, specialty fluids, additives and synthetics. The journal includes timely articles on the demulsification, desalting, and desulfurizing of crude oil; new flow plans for refineries; platforming, isomerization, catalytic reforming, and alkylation processes for obtaining aromatic hydrocarbons and high-octane gasoline; methods of producing ethylene, acetylene, benzene, acids, alcohols, esters, and other compounds from petroleum, as well as hydrogen from natural gas and liquid products.
