Abstract

The second and third class oil reservoirs in Sazhong Development Zone of Daqing Oilfield are distributed horizontally and longitudinally, and it is difficult to subdivide and develop. The third class reserves of the second class oil reservoirs account for 41% (25.9% off-balance sheet). In order to realize simultaneous exploitation of reservoir potential in Pu II group, the three types of reservoirs that are difficult to be used by chemical flooding should be explored in the water flooding stage. However, the three types of reservoirs have the characteristics of poor development and poor connectivity, so it is necessary to achieve fine exploitation through measures. Taking BQ block of Sazhong Development Zone of Daqing Oilfield as an example, this paper has achieved good results by optimizing potential Wells, designing reasonable fracture penetration ratio and optimizing fracturing technology. Field practice has proved that compared with ordinary perforating production, the strength of sandstone production in fractured well is increased from 2.48m³ /d.m to 5.1m³ /d.m, and daily oil production is increased by 3.76t.
