摘要
稠油油藏好油层的岩心均为不成形的散砂,而能够做试验的岩心为胶结好的非油层或差油层的岩心,显然这种岩心试验结果不能代表整个油藏。通过对新疆油田百重七油田T2k2稠油油藏的岩心试验结果分析,建立了胶结指数与孔隙度之间的关系式。与传统方法相比较,该方法预测的地层因素的结果更加接近岩电试验资料。
Cores of better oil reservoirs are fragmentary in heavy oil reservoirs, and the cores used in experiment of rock-resistivity are better cemented ones. Obviously, the result of rock-resistivity experiment dose not cover all the oil reservoirs. By analyzing the experimental data of rock resistivity in T2k2 heavy oil reservoir of Baichongqi Oilfield, a correlation is found between cementation exponent and porosity. Comparing with conventional method, the cementation exponent forecasted by the method is consistent with the experimental data.
