Application of Horizontal Well Drilling and Completion Technology in Desert Oil Fields with High Temperature and High Pressure

Abstract

In this study, horizontal well drilling and completion technology was studied in desert oil field under high temperature and high
pressure environment. Through the construction of multi-field coupling simulation model, the drilling and completion scheme is optimized,
and the core technology system including high temperature and high pressure directional drilling, wellbore integrity assurance, dynamic sand
control and intelligent leakage plugging is formed. Field application results show that the technology system can control the bottom hole temperature at 198-202C, the annular pressure is basically stable at 68-72MPa, and the maximum stress of casing is less than 485MPa. The wall
stability coefficient is basically maintained at about 0.92. Compared to traditional production processes, new drilling cycles were reduced by
23%, complex accidents were reduced by 67%, and initial production was increased by 41%. The research results can provide reliable technical support for the safe and efficient exploitation of high temperature and high pressure reservoirs in desert oil fields.
