| 摘 要： | 油气藏在地表产生的自然电位属于静位场, 其强度与场源量成正比, 与距离场源的半径成反比.理论研究与实践结果表明, 自然电位异常可以指示含油砂体, 圈定油气富集区.在储层套数较少的含油区可以用电位强度与视有效厚度的线性关系来预测油层厚度.卫星油田储层套数较少, 其视有效厚度可用线性方程h=-0.19x+0.74来表征, 为配合下一轮滚动开发工作, 在地质研究的基础上, 在地质研究难度较大的卫102、卫262、卫20地区应用自然电位预测有效厚度, 达到优选井位提高钻井成功率的目标.

| Abstract: | The upper spontaneous potential produced by oil and gas accumulation remains with stable potential field. Its intensity is in direct ratio to the content of the source and in inverse ratio to the radius apart from the source. Theoretical researches and practice show that abnormalities of spontaneous potential can indicate oil-bearing sandstone and locate oil-and-gas-enriched area. In oil area which is devoid of sufficient reservoir beds, the thickness of the petroleum reservoir can be predicted by determining the linear relationship between potential intensity and apparent effective thickness. In Weixing field, which is devoid of sufficient reservoir beds, its apparent effective thickness can be predicted by the linear equation. Based on the geological research and by applying spontaneous potential, the effective thickness is predicted for selecting the most appropriate drill sites to increase the possibility of successful well boring for the next round progressive development. |
