Hot water, steam, or gas is injected into the producing formation to lower the viscosity of the oil and force it through the reservoir toward producing Wells.
向产层注入热水、热蒸汽或热气体，以降低油的粘度，并将油经储层压向生产井。
The high temperature gas drive agent developed through study is good at foaming and viscosity reduction and is non-pollutive to oil reservoir.
研究表明，开发研制出的高温气体驱油剂具有较好的发泡和降粘作用，且对油层不产生任何污染。
