裂缝性储层非均质性强,成藏条件复杂,预测难度很大。为提高该类储层预测的精度,研究了一种新的构造裂缝定量预测技术——构造正、反演裂缝预测方法。将该技术应用于胜利油田埕北30古生界潜山,预测了各目的层的裂缝分布和方位,预测结果与测井资料得到的裂缝方位有较好的一致性,2口新井的实钻情况也证实了裂缝预测结果的可靠性。

The inhomogeneity of fractured reservoir and the complexity in oil-gas concentration offer a challenge to reservoir prediction. A new structural fracture prediction technique, called structurally forward and inverse fracture prediction, was presented in this paper. This method has been applied in predicting the fracture distributions and orientations of the targeted intervals in the Chengbei 30 Paleozoic buried hill in Shengli Oilfield. The predicted results are in good agreement with those from logging data, and are confirmed by two newly drilled wells.
