New productivity prediction model Tor sand control wells by cyclic steam stimulation
摘要
Abstract
There are many productivity prediction models for heavy oil wells with cyclic steam stimulation, but these models have little consideration on effects of sand control measures for the productivity, however, sand control measures are necessary for heavy oil stimulation, which result in some errors in calculation of the productivity. This paper presents a new productivity two zone model which considers the interaction of steam stimulation and sand control, and this model also combines the gravity override effect and the rheological behavior of heavy oil, then, it gives an actual example. Comparing with conventional models, the heating radius calculated through new model are greater and the calculation error is approximately 5% , which proves its validity. Based on negative power exponent of the heating radius hypothesis, the new model should not consider the heating area, shape and the influence of the reservoir thickness. The computing workload for new model is small and it is easy to use, which can provide plan for the productivity prediction for sand control well with thermal recovery.关键词
