摘要针对影响膏体充填材料强度的因素，通过大量的试验，揭示了以河砂为骨料的膏体充填材料强度与各影响因素间的关系。 - The design strength of the new concrete is c40 , which adopts 525 # common portland cement , the sand is middle wide river - sand , the radius of coarse aggregate is 10 - 30mm . the surfaces of the old concrete which are harnessed are divided into i , ii , iii three type faces
Znfl ， ao新混凝土设计强度等级选用c40 ，采用525 ’普通硅酸盐水泥，砂是中粗河砂，粗骨料的粒径为川30mm 。老混凝土表面处理后的表面分为1型面、 11型面、 ill型面三种类型。 - To braided stream deposit , the fluvial sand body is distribute largely and continuously , so the heterogeneity is poor relatively , the relation of injection and production is better in the case of rare wells , about all wells have come on water , only in some thin sandbodys or bad physical layers there is some low flooded strata
对辫状河砂体，平面上大面积连续分布，在平面及层内非均质性弱，在较稀的井网下注采关系就较完善，目前平面上几乎所有井点都已水淹，只有局部由于砂体厚度变薄，物性相对变差而存在一些低水淹部位。
