The microemulsified acid system composed by diesel oil, hydrochloric acid and emulsifier was investi- gated in this paper. The stability of microemulsified acid and the phase behavior of the microemulsified system Were studied. The size distribution and the corrosion inhibition performance were also observed. The results showed that the diesel oil microemulsified acid system possessed small size and good stability under different temperature.The tolerance to CaCl2 reached 80 g·L^-1. Compared with the same concentration hydrochloric acid solution, the corrosion inhibition performance of the diesel oil microemulsified acid system was remarkable. 相似文献

广西玉林市化寿水库灌区,经过十几年不断的研究试验,现又总结出一整套适用于当地的节水高产措施——“薄浅湿晒”灌溉制度。特别是在1989年到1991年连续三年大旱中,主库蓄水量少,灌溉用水严重不足,他们采取主库灌关键水(即保插、保孕穗后期和扬花三水),水稻其余生育期需水,则由小塘库、陂坝、降雨提供,严格执行“薄浅湿晒”灌溉制度,再辅以其它农业生产技术措施,结果仍取得了下列好成绩: 相似文献

Petroleum and nature gas not only are important resources,but also are important strategic materials of our country.All methods the enhancing the producing degree of petroleum and natural gas reservoir,increasing single well production and extending the stimulation period of validity are important stratagem for petroleum and natural gas exploitation.Fracturing and acidizing are the main methods for stimulation as well as one of representative examples of rheology theory application in engineering.Based on analysis of low permeability reservoir characteristics,the fracturing and acidizing stimulation principles and main controlling factors were discussed.And the mechanical characteristics,chemical reaction and rheological behavior in the stimulation process were reviewed.Furthermore research trends afterwards including the material and fluid rheology in oil and natural gas production process,the deep rock fracture initiation and extension rheology,and the fracturing and acidizing application rheology were also proposed in this paper. 相似文献

柴油微乳土酸的制备及其性能研究 总被引:1,自引:0,他引:1
微乳土酸在石油与天然气开采方面有着重要的潜在应用价值.今以柴油、土酸、表面活性剂和助表面活性剂为主要原料,制备了缓蚀性能良好的微乳土酸体系.考察了阳离子表面活性剂CTAC和非离子表面活性剂AEO9的配比对微乳土酸体系70℃下的稳定性、增溶性的影响,并给出了解释.通过添加CaCl2对微乳土酸体系的耐盐性进行了研究.比较了微乳土酸体系和同等浓度下的常规土酸分别与石英砂、碳酸钙、标准钢片的反应,结果表明,与相同酸浓度的土酸溶液相比,柴油微乳土酸体系的缓蚀效果显著.当乳化剂为下列组成时:CTAC/ AEO9=3:2,正丁醇/ 正辛醇=1:2,助表面活性剂/表面活性剂=1:2,可得到较大的微乳土酸单相区. 相似文献
