针对稠油藏在蒸汽吞吐开采时．其产量呈周期性变化的特点，建立了自适应混合回归模型，用来估计蒸汽吞吐稠油藏的最优参数，拟合、预报稠油蒸汽吞吐产量。应用该模型对辽河油田Ｄ６６等区块进行了拟合和预报．获得了个人满意的结果。该方法对稠油热采长远规划、年度计划及开发方案的编制具有重要的作用。
For heavy oil reservoirs when steam huff and puff. The yield of which was changed periodically. An adaptive mixed regression model was established to estimate the optimal parameters of heavy oil reservoirs and fit and predict the throughput of heavy oil steam huff and puff. This model is used to fit and forecast D66 and other blocks in Liaohe Oilfield. Received personal satisfaction with the results. This method plays an important role in the long-term planning, annual plan and development plan of heavy oil thermal recovery.
