Study and application of wellbore trajectory optimization for dense cluster wells

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