GD14H, a horizontal well drilled in tight reservoir of Dagang Oilfield, reveals complex lithology, large burial depth, and poor physical properties. In order to improve its fracturing performance, a new technique of multi-cluster network fracturing was adopted based on a series of optimized multi-cluster perforation parameters and fracturing treatment parameters, and the 15-cluster fracturing was determined. Field test has demonstrated outstanding stimulation results. Moreover, the horizontal well fractures monitoring via the stable electric field/potential method shows that the measured results match well with the results of physical model for GD14H. The successful application of this technique in Dagang Oilfield implies a great breakthrough in the fracturing of tight oil horizontal wells in Dagang Oilfield, and lays a valuable foundation for stimulation of other similar tight oil and gas reservoirs.
