| description | The oilfield has entered the ultra-high water cut period, the distribution of remaining oil is scattered, and it is difficult to tap the potential. On the plane, affected by sand body distribution and well pattern production objects, sand body perforation does not correspond to each other, forming residual oil with imperfect injection production relationship; The residual oil formed in the retention area at the edge of the fault due to the influence of fault shielding. Vertically, affected by the heterogeneity, interlayer and rhythm in the layer, the bottom of the thick oil layer is strongly washed, the middle is moderately strongly washed, and the top is weak and not washed. The production difference is large, and the remaining oil mainly exists at the top of the oil layer. The remaining oil with imperfect injection production relationship and special parts is tapped through ultra short radius horizontal wells to improve oilfield development efficiency. |
