杜66块为薄互层状稠油油藏，在稠油油藏中具有一定代表性。油藏非均质性较为严重，纵向动用程度不均。通过各种监测资料的统计与分析，结合数值模拟，对采用蒸汽吞吐生产方式的油藏纵向动用程度进行了综合研究与评价。分析了提高油藏动用程度的影响因素，并制定了提高储量动用程度的对策，从而为该块及同类型油藏的开发提供了依据。

Du-66 Block is a thin interbeded inspissated pool, which is a representation of inspissated oil reservoirs and has a serious heterogeneity with uneven produced degree. The vertical produced degree of reservoirs that took steam stimulation as an exploitation mode were investigated and evaluated comprehensively by analyzing all kinds of test data combined with mathematical simulation. The influence factors in promoting reserves produced degree were analyzed and a series of measures were established. The research provides a basis for exploitation in this block and in the same type of oil reservoirs.
