In the middle and late stage of oilfield exploration and development, the difficulties such as land acquisition on the surface, high density of underground well pattern and high development cost are serious. Dense cluster Wells are mainly way to development mode transformation and quality and efficiency improvement. Combined with the practice of dense cluster well in Dagang Oilfield, the paper detailed analyzes the difficulties faced by the design of dense cluster well drilling engineering, which including well pattern arrangement, wellbore trajectory optimization, wells anti-collision, all of those are beneficial to realize benefit drilling development. The applications show that this technology has a significant effect on improving wellsite utilization rate, shortening drilling cycle and reducing drilling cost in Dagang oilfield, and has a very important reference and popularization significance in similar oilfield development.
