摘要
底水油藏开发过程中地质导向效率主要受到储层非均质性、油水分布的复杂性以及构造预测的不确定性的影响。因此,需要准确的定量刻画井眼附近的储层特征,才能有效的控制轨迹贴顶钻进和抑制底水锥进。由此,引入了超高清随选油藏描绘仪(PeriScope Edge)工具提供的超高清随钻油藏描绘技术,通过反演井眼周围一定范围内的储层特征,来指导地质导向施工。综合分析验证了PeriScope Edge技术在底水油藏精细开发中的有效性。
In a bottom-water reservoir,the geosteering efficiency is mainly affected by the reservoir heterogeneity,the complexity of fluid distribution and the uncertainty of structure prediction.It is necessary to accurately quantify the reservoir characteristics near the wellbore to effectively control the trajectory close to the oil zone top and inhibit the bottom water coning.Accordingly,PeriScope Edge Ultra-high-definition Reservoir Mapping-while-drilling technology is introduced to guide the geosteering execution by characterizing the reservoir profile around the wellbore with a specific depth-of-detection.The comprehensive analysis verifies the effectiveness of PeriScope Edge technology in the fine development of bottom water reservoir.
