摘　　要：方法利用数值模拟技术，研究茨１３块稠油油藏注稠化水开发方法。目的优选注稠化水方案，提高茨１３块开发效果。结果稠化水驱不宜注入较高浓度的稠化水，而且应避射底水，其效果优于水驱。经济评价认为，方案六和方案七为最优方案，先实施方案六，见效后，再实施方案七；方案实施中，应注意油层解堵、配产、配注等问题。结论稠化水驱可以提高稠油油藏的采出程度，增加产油量；Method\ Numerical simulation technique is applied in Ci 13 fault block to find out methods for developing heavy oil reservoir by injecting viscous water. Purpose\ To improve development result by optimizing viscous water injection scheme. Result\ Viscous water drive is superior to water drive, but viscous water with high concentration will not produce favorable result and bottom water should be avoided when applying this technique. Based on economic evaluation, plan 6 and 7 are the most optimum and they should be applied in sequence if favorable results appeared. Also, oil bearing formation de-plugging, production distribution, injection volume distribution and etc should all be paid attention to. Conclusion\ Viscous water drive can improve recovery degree of heavy oil reservoir and increase production. Ci 13 fault block is suitable for displacing with viscous water drive.
