摘要： 分别从砂的流入提高液体流动速度、高渗透区的形成、泡沫油的形成以及降低油井的表皮系数等4个方面对出砂冷采提高油井产能的机理进行了研究,加深了人们对出砂冷采理论基础的了解和认识;同时指出油井产能提高的主要机理和主导油井出砂的因素是随时间不断变化的。

Abstract: This paper presents the in-depth research of mechanism of enbancing heavy oil well productivity by sand-producing cold pro-duction and includes the increase of fluid flow by sand inflow; the formation of high permeability area; the formation of foaming oil and the decrease of skin effect. They may improve the understanding and recognition of the theoretical basis of sand-producing cold produc-tion in heavy oil well. In addition, the study indicates that the mechanism enhancing well productivity and factors controlling sand pro-duction are changing with time.

Key words: heavy oil, sand production, productivity, mechanismi
