摘　　要：产能预测是一种对储层产油能力进行综合评价的技术,对油气田的勘探与开发有着极其重要的意义。对于中、高孔渗油藏,油水渗流基本服从达西渗流定律,产能预测相对来说比较简单。而对特低渗透储层而言,渗流机理非常复杂,影响产液能力因素也更多更突出,产能预测难度非常大。对低孔低渗储层产能进行正确评价既是提高油气田勘探效果的关键环节,又可以为开发的部署与规划提供重要的基础数据。The productivity prediction is a technique to comprehensively evaluate productivity of reservoirs, which has great significance for exploration and development of oil-gas fields. For middle and high permeability reservoirs, the crude oil seepage flow basically accords with Darcy law, the productivity prediction is easy. But for low porosity and low permeability reservoirs, their percolation mechanisms are very complicated, there are many key factors for the productivity prediction, so their productivity prediction is very difficult. How accurately to evaluate productivity of low porosity and low permeability reservoirs is not only a key link to increase exploration effect of oil-gas fields, but also can provide basic data for deployment and planning of oil-gas field development.
