由华北石油管理局井下作业公司和陕西汉中地区食品机械研究所、面粉厂联合研制的磨芋石油压裂液通过了省级鉴定.实验证明磨芋石油压裂液流变性好、携沙性强、残渣低、滤失少、耐细菌腐蚀性好、热稳定性和抗剪切性好,产品具有良好推广价值. 位于怀俄明州西南部即使含H_2S仅为5%而含CO_2高达66%的LaBarge气田亦出现了发硫沉积问题.现场经验表明,DMDS(二甲基二硫)和DADS(二芳基二硫)都是有效的硫溶剂,DADS因价廉、挥发性低、容易再生等优于使用DMDS.
The ground oil fracturing fluid jointly developed by North China Petroleum Administration Underground Operation Company and Shaanxi Hanzhong Food Machinery Research Institute and Flour Mill passed the provincial appraisal.The experiment proves that the rheological property of the ground tar oil fracturing fluid is good and the sand carrying capacity is strong , Low residue, less filtrate loss, good bacterial corrosion resistance, good thermal stability and shear resistance, the product has a good promotion value. Located in the southwestern Wyoming even with H 2 S only 5% and up to 66% of CO_2 66% LaBarge There are also sulfur deposition problems in the gas field.The field experience shows that both DMDS (dimethyldisulfide) and DADS (diaryldisulfide) are effective sulfur solvents and that DADS is superior in cost, low volatility and easy regeneration Use DMDS.
