Abstract: Different problems such as presence of formation leakage, poor drillability, drilling tool wear, difficult well trajectory control exist in offshore oilfield buried hill reservoir drilling development process. To solve these problems, first of all, an indepth analysis of the drilling, is made. Based on the analysis results, combined with the experience of offshore operations, several measures are applied, including managed pressure drilling (MPD), oil in water mud system, optimization of tools (especially bit, EcoScope, drag reducer and screw motor) and parameters optimization. With the application of these measures, trajectory control is achieved for all buried hill wells, the reservoir development purpose is attained, and no drilling accident happens. The use of these technologies forms a series of supporting solutions to the development of offshore oil field in buried hill wells.
