摘要
直流电场采油是国外六十年代发展起来新的三次采油技术 ,它是利用直流电场对岩石地层中油、水相渗透率的影响 ,达到提高原油最终采收率的目的 ,针对岔河集低渗透砂岩油田的开发特点 ,在调研和室内论证的基础上 ,选取了岔 31— 110井组进行直流电场采油试验 ,单井平均日增油 1.2t,单井日降水 1.
Direct current field oil extraction is a new technology of third time oil recovery.It is to make advantage of direct current field's effect on coefficient of permeability of oil and water in lithostratigraphy,therefore,final rate of crude oil recovery goes up.On the basis of investigations and analyses,Ca 31-110 oil well crew is chosen to conduct the experiment of direct current field oil excraction,as a result,A single well has an anerage increase of 1.2t oil and has an average decrease of 1.3m 3 water every day.
