| 摘 要： | 从几何学的观点出发,针对纯油藏和具有气顶的油气藏,采用单储系数、横截面面积与油层横向分布长度三者乘积的方式改进采用单储系数、含油面积与油层厚度三者乘积方式的传统容积法,提出相应的地层不整合遮挡油气藏地质储量计算新公式,并根据油气藏的特点提出水平井钻遇油气藏厚度的预测公式。地层不整合遮挡油气藏的地质储量计算目前主要采用容积法,这类方法不仅计算繁琐,而且不确定因素较多;改进后的新方法计算简单方便,理论性更强,存在的不确定因素显著减少。采用新方法在高青油田高424块高424-1井区进行了实践应用。实践表明:改进的新方法适用于地层不整合遮挡油气藏的地质储量计算及预测水平井钻遇油气藏厚度。
