CA油田稠油油藏热采数值模拟研究

由于江苏油区CA油田稠油油藏多层状砂泥薄互层的独特性，现场开发难度很大。为了论证热力开采的可行性，采用油藏数值模拟技术，结合经济效益评价，对热力开发组合方式、布井方式与井距、油藏条伯对热采效果的影响进行了研究，确定了合理的开采方式为弹性-蒸汽吞吐-水驱。

Research on numerical simulation of the thermal recovery in heavy oil reservoirs of CA oilfleld

Owing to the unique characteristic of the multi-layered thin sand-shale interbeds in CA oilfield of Jiangsu petroliferous province, it has great difficulty in field exploitation. In order to demonstrate feasibility of thermal recovery, combination way of the thermal recovery, well pattern and well spacing, and the influence of reservoir conditions on the thermal recovery effect are studied by using reservoirs numerical simulation technique and combining with evaluation on economic benefit. Reasonable method of exploitation is elasticity, then cyclic steam stimulation, and water flooding at last.
