The preparation of construction cementing medium from phosphogypsum and blast furnace slag has been studied, highlighting the mixing ratio of the raw materials and the product performance. 介绍了利用化工副产品磷石膏和高炉矿渣制备建筑胶结料的方法。
Both laboratory and field tests have shown that the MTC with exciting agents can meet the needs of cementing operation for medium casing. 室内两类泥浆模拟试验以及现场一类泥浆固井实践均表明,采用激活剂技术的MTC综合性能满足技术套管固井要求。
Condensation delay cementing method; The Refraction of Electric-field Intensity on the Demarcation of Dielectric Medium 延迟凝固注水泥;场强在电介质分界面上的折射规律
According to the criterion, the article examines the cooperative performance of steel plate working together with CFRP and cementing medium by fatigue experiment. 本文参照规范,以应力幅准则为依据,通过疲劳试验检验了胶结在一起的纤维材料和钢板在高次循环弯曲荷载作用下的协同工作性能。
Completion with external casing packer features high dally production and long period of production while cementing with filtrate reducing cement slurry system results in medium daily production. 采用管外封隔器完井,日产量高,生产周期长;采用降失水水泥浆体系固井,日产量适中。
