摘　　要：通过分析区块开发形式和存在的问题,进行了出砂冷采后多种开发方式的标准筛选以及此技术在该油藏的适应性研究,结合火驱物理模拟实验,明确了该区块进行火驱的可行性;利用数值模拟技术,优选了火驱合理的井网方式和注气参数。2007年开始,通过开展现场试验,见到了较好的效果,为提高区块采收率提供了技术支持。The development schemes after cold production with sand have been screened and their applicability has been studied for the Taobao heavy oil reservoir based on analysis of the development situation and existing problems. It has been determined through physical simulation tests that in-situ combustion is feasible for the reservoir. Rational well pattern and air injection parameters have been optimized through numerical simulations. Since 2007,field tests have achieved satisfactory result,and provided technical support for improving reservoir recovery factor.
