关于压裂，你必须知道的20个常识！ 知乎 知乎专栏
Web—加砂过程中要保持压裂设备的性能始终处于良好工作状态，保持加砂的连续性。 —加砂排量要按照压裂施工设计要求进行，保持稳定，不准随意升降。 —加砂中出现下列情况时，应停止加砂，采取用液量大于油管容积和油套环形空间容积之和的压裂液进行循环替挤或 Web粗细不同的粒径按照一定的比例组合搭配在一起，以达到较高的密实程度。 在土木工程中，粒径大于475mm的骨料为粗骨料，又称为“石子”；粒径介于015mm~475mm之间的 为什么搅拌水泥的时候要加沙子？ 知乎
纯水泥强度大还是加沙强度 百度知道
WebJul 22, 2014 少量的纯水泥强度要高于加沙水泥，但对于住宅、工业建筑等混凝土结构件，那也不可能采用纯水泥制作，必须采用碎石骨料、加沙和水泥配合比，才能最大限度 Webcupcup
压裂加砂强度怎么计算百度问一问
WebSep 24, 2022 压裂加砂强度怎么计算 您好，很高兴为您解答。 由于混凝土中的砂子完全填充于石子的空隙中（空隙率p），每立方混凝土中砂子的准确用量为砂子的堆积密度乘以 Web密切割'水平井体积改造是开发页岩油藏的有效手段，裂缝间距和井距是'密切割'水平井体积改造设计的关键环节。基于Comsol建立了离散裂缝网络数值模型，对'密切割'体积改造油藏进行仿真模拟，研究了裂缝间距、井距、裂 页岩油藏“密切割”体积改造产能影响因素分析
砂比砂浓度混砂液密度铺砂浓度之间关系pdf原创力文档
WebJul 25, 2020 国 外推荐，要想成功的获得较好的导流能力，建议铺砂浓度在 98 ～4883 kg/m 2 ，由此看 来，平均砂浓度 426 kg/m 3 ，也就是平均砂比为 235%左右，的确不是 WebJan 9, 2018 混凝土的强度主要是配比决定，理想状态下水泥和石子结合的强度跟纯水泥一样。 （可以看成单位体积里都一样是水泥。 水泥与石子，裂缝可以忽略，因为配比合理 水泥浆的强度与混凝土的强度哪个高？ 知乎
