Fractured model in flat bed and permeable belt model are used to simulate real medium in order to find a method of inversing fracture width and permeability of formatiom. From the propagation characteristic of Stoneley wave in fractured strata and permeable strata, the reflected Stoneley wave is employed to inverse the fracture width and permeability of the strata. When the central frequency is 1 kHz and its frequency width is ±500 Hz, reflective coefficients from synthetic Stoneley wave are equal to calculated...

Fractured model in flat bed and permeable belt model are used to simulate real medium in order to find a method of inversing fracture width and permeability of formatiom. From the propagation characteristic of Stoneley wave in fractured strata and permeable strata, the reflected Stoneley wave is employed to inverse the fracture width and permeability of the strata. When the central frequency is 1 kHz and its frequency width is ±500 Hz, reflective coefficients from synthetic Stoneley wave are equal to calculated ones. The results show the inverse fracture width and permeability are consistent with given values.

为了寻找反演地层裂缝宽度和渗透率的方法,采用平板状裂缝模型和渗透带模型模拟实际地层,根据斯通利波在裂缝性地层和渗透性地层中的传播特性,提出用反射斯通利波反演地层裂缝宽度和渗透率.当声源的中心频率为1kHz时.在±500Hz的范围内,从合成斯通利波波形中处理得到的反射系数与计算的反射系数相等,反演结果表明,地层裂缝宽度和渗透率的反演值与给定值相符.

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...

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.

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。
