溶剂酸解堵在沈阳油田的应用

Application of solvent acid for broken-down in Shenyang oilfield

溶剂酸解堵技术是针对沈阳油田高凝油特殊原油物性而研制的 ,该技术由有机溶剂和无机酸液两部分组成 ,有机溶剂解除由于冷伤害造成的蜡堵 ,无机酸液解除机杂和岩石颗粒造成的无机堵塞 ,即通过溶剂酸的作用同时解除高凝油有机、无机堵塞 ,提高解堵效果 ,提高油层渗透能力 ,恢复油井产能。

Solvent acid for broken down is especially developed in accordance with physical properties of high pour point oil in Shenyang oilfield. It consists of organic solvent and inorganic acid. The organic solvent can remove paraffin blockage due to cold, and inorganic acid fluid can remove inorganic blockage due to dirt and rock grains. Therefore, this solvent acid can remove both organic and inorganic blockages simultaneously, thus improving broken down efficiency and reservoir permeability, and bringing oil wells back to production.
