具有压敏特征的稠油油藏水平井产能分析
Analysis of production of horizontal wells in heavy oil reservoir with pressure sensitive characteristic
摘要
Abstract
On the basis of the steady flow theory of power law flow pattern in the deformed media and the description of inner and outer seepage region of the horizontal well which presented by Chen Mingqiang, the horizontal well productivity formula of heavy oil with power law characteristic in deformed media was derived, and the formula concluding three flow pattern. The method for resolving the equation was presented by the equivalent principle of flow rates and pressures at regional boundaries, and the productivity can be gained. The reasonability and practicability of the calculated solution was proved by comparing with the practical production. The analysis for power law exponent, deformation coefficient and start-up pressure gradient shows that the horizontal well's production in heavy oil is inverse-related with the start-up pressure gradient and deformation coefficient, the production decreased quickly when the power law coefficient increased.关键词
