国内外出砂机理研究现状综述

RESEARCH ON SAND PRODUCTION MECHANISM AT HOME AND ABROAD

目前在出砂机理方面的研究国外较多 ,而国内偏少 ,为了更好地了解国内外在出砂机理方面的发展情况 ,立足于对出砂机理的研究 ,纵向回顾几十年来国内外在出砂机理方面的研究现状 ,从而能对出砂机理方面的理论有一个新的认识 ,有利于开拓视野 ,进一步搞好防砂和控砂工作。

The problem of sand production in oil and gas well is very popular.Sand production can shorten the life of oil and gas well,wear out the downhole tools and equipments,block or bury well bore,reduce the productivity of the oil and gas well,and eventually make the well useless.Therefore,the research of the sand production mechanism is important for sand control in oil and gas well.The paper presents the research status quo of sand production mechanism at home and abroad and obtains a new recognition for sand production.It is propitious to sand control.
