摘　　要：稠油热采中，由于注入碱性蒸汽对储层碎屑发生溶解作用，导致油井出砂严重，目前已成为国内外稠油热采中一个重大疑难技术问题。本文主要对河南油田出砂最严重的泌浅１０块Ｇ５１３１０岩心样品，模拟现场热采条件进行碎屑溶解实验并探讨其地质意义，以期能对其它稠油油藏的开采具有参考价值。In the process of heat mining of heavy oil, sands seriously come out from oil-well as a result of interaetion of clasts of the reserviors with the injected alkaline steam, which remains a technical problem in the world. 10 core samples from the most severe sand well of Biqian G51310 of Henan oil field were experimented on elastic dissolution under site heat mining conditions. Their geological significance was discussed, which may provide some useful information for heat mining of heavy oil.
