塔里木盆地英买力潜山油藏储层出砂预测研究

Prediction of Sand Production in the Qianshan Reservoir Rock,Yingmali,Tarim Basin

塔里木英买力潜山油藏包括寒武、奥陶、志留、石炭系油藏.志留系砂岩储层主要是灰色、灰白色细~中粒岩屑石英砂岩,砂岩中石英的含量高,岩石压实作用好.开发过程中,出砂情况和预期结果相差较大,为准确预测该地区的出砂情况,利用国内常用的组合模量法和祁大晟等（2007）修正的组合模量公式对该地区的出砂情况进行详细的分析和预测.修正后的组合模量公式与生产中的出砂情况吻合较好,能够有效地指导生产实践.

Qianshan Reservoir Rock in Yingmaili, Tarim Basin is characteristics with Cambrian, Ordovician, Silurian, and Carboniferous system. The sandstone of Silurian system is mainly composed of hoary or gray small or middle quartzite, in which the quartzite is high content and the compaction is good. In the mining, the actual sand production and the prediction have a larger difference. For the accurate prediction, the combined modulus monograph, which is habitual to be used in China, and the composite modulus formula（2007）, which was amended by Qi Dasheng, are adopted to analyze and predict the sand production in detail. The amended formula is identical to the actuality of the sand production, so it can direct the production effectively.
