Abstract: Open hole gravel packing of horizontal well can effectively control sanding and bottom water coning. However, open hole gravel packing for slim hole horizontal well cannot be performed smoothly thanks to a series of bottlenecks, such as small borehole size, large curvature, rapidly changed flow resistance and down-hole pressure. Qinhuangdao 32-6 Oil Field is a typical high-porosity and high-permeability loose sandstone bottom-water heavy oil field. The 32-6E platform smoothly completed gravel packing service for five slim hole horizontal wells thanks to reasonable design of wellbore structure and well trajectory, optimization of drilling and completion fluid system, adoption of gradient high-quality screen pipes and adjustment of packing parameters. This paper makes briefings about the concrete measures, such as pipe scraping, well rushing, sand control soaked gel-breaking as well as the results of those measures. The open hole gravel packing completion process entirely meets the requirements on horizontal well and achieves good results of oilfield development.
