Abstract

It is vulnerable to be damaged by Jamin effect in the process of flood development, so it is difficult to extract oil in the low permeability and the recovery efficiency is low. Taking a well field in Tarim Oilfield as an example, Jamin effect evaluation experiment and evaluation standard are designed and set by water/oil displacement experiment of natural standstone. Using Jamin index to estimate Jamin damage, sifting kinds of surfactants, carry out laboratory test of redcuing Jamin effect. The experimental results show that the research well field has middle-strong Jamin effect, which can be reduced effectively by reducing the interfacial tension. The results show that the method of reducing oil—water interfacial tension by adding 0.01% Gemini Surfactants to injected water can graeatly reduce Jamin effect and improve the recovery efficiency.
