Research on Evaluation Method of Monitoring Interwell Steam Channeling in Heavy Oil Thermal Recovery Well

摘要

This paper presents interwell steam channeling features of huff & and puff in heavy oil and super heavy oil reservoirs. The mathematical approach for describing oil producing level between wells is established based on data from a high temperature manometer hanged under pump. The flowing temperature and pressure data represents the characteristic parameters of interwell steam channeling path, and therefore the features of residual oil distribution is obtained. In a field test example, Du block 84, which is super heavy oil reservoir with huff & puff stimulation in Liaohe Oilfield, is selected for making evaluation and analysis on interwell steam channeling features during steam stimulation. The results approve that this technique has great important significance in understanding interwell residual oil distribution and guiding heavy oil field development in later period.
