Well Qiao7 - P - 1, which is the first well of adopting the long horizontal section multistage subsection frac- turing technique, is an unconventional horizontal well in tight sandstone reservoir in Jiangsu Oilfield. This paper first intro- duces reservoir characteristics,wellbore configuration, tight sandstone reservoir characteristics and slim - hole drilling fluid property, and secondly analyzes difficulty points of drilling fluid technology. Finally, the drilling fluid formula, the process- ing technology, application effect, and recognition and suggestions are introduced in detail. The success of this well provid- ed important guiding significance to the subsequent drilling operation of Jiangsu Oilfield.
