美国休斯顿德士古公司开发出一项从地下岩层结构溢流石油的新化学溢流技术,利用廉价而有大量来源的造纸厂副产物木素。在典型的油井,1/3的石油可由油井泵油抽出,另外1/3由注水取出,剩余1/3要用化学溢流取得。当然,不可能把全部石油都抽取干净,目前采用石油磺化盐表面活性剂进行石油化 Texaco, Houston, USA, has developed a new chemical spillover technology that spills oil from underground rock formations, using inexpensive and abundant sources of lignin, a by-product of paper mills. In a typical well, one-third of the oil can be extracted from the well pump oil, the other one-third from the water taken out, the remaining 1/3 to obtain with chemical overflow. Of course, it is impossible to extract all of the oil and it is currently petrified with petroleum sulfonate surfactant
