| 摘 要： | 在疏松砂岩稠油油藏中，油井适度出砂能大幅度提高产能，国内、外有很多稠油出砂冷采成功的例子。出砂能够提高油井产能主要是因为砂的流入提高了液流速度、井筒周围高渗透区的形成、泡沫油的形成以及降低了油井的表皮系数。本文给出了出砂率与时间、产量与时间之间的定量关系。

| Abstract: | In unconsolidated sandstone reservoirs, proper sand production may result in significant increase in oil production. There are a lot of successful cases of cold production with sand at home and abroad. The inflow of sand may accelerate flow stream velocity, form high permeability zone around wellbore and foam oil, and reduce the skin factor of oil wells. This paper also provides the quantitative relationships between sand cut and time, and production increment multiple and time. |
