摘要
分子膜驱油剂是一种新型驱油剂,它主要是使岩石表面亲油性转为中性,从而剥离油膜,通过自发吸附作用驱替出孔隙内的残余油。分子膜剂的优点有驱油效率好、不污染储层、价格低、投资少。结合双河油田中低渗储油层的实际情况,通过对分子膜剂性能的评价,筛选出了适合河南油田中低渗储层的分子膜剂类型和浓度;室内实验结果显示,分子膜驱油在原来水驱基础上可以提高采收率,效果明显。
Monolayers displacing agent is a new drive oil,it is mainly the rock surface into neutral lipophilic,thereby stripping film,through the spontaneous adsorption displacement of residual oil within the pores.The advantages of the molecular film former oil displacement efficiency is good,do not pollute the reservoir,low price and low investment.Shuanghe oil fields with the actual situation of low permeability reservoir,through the performance evaluation of the molecular film former,screened out for low permeability reservoirs in Henan Oilfield type and concentration of the molecular film former;laboratory experiments showed that monolayers Flooding on the basis of the original water flooding can increase oil recovery,the effect is obvious.
