火烧油层又称“火驱”，是稠油蒸汽吞吐开发后期主要接替技术之一，火驱过程中原油在地层中高温燃烧，发生复杂的物理化学反应，储层内部会发生固相、液相、气相的物化、地化反应，造成岩石矿物溶解、沉淀和蚀变以及油、水组分的变化，进而影响储层内岩石矿物、孔隙结构、物性流体性质。运用岩石薄片、 X-衍射全岩、铸体薄片、全烃色谱等十余项分析测试技术进行研究，揭示蒸汽吞吐转火驱开发储层岩石矿物变化规律，储层物性变化特征、孔隙结构变化特点、流体组分变化特征，为稠油蒸汽吞吐转火驱开发储层变化研究提供了较好技术借鉴。
火燒油層又稱“火驅”，是稠油蒸汽吞吐開髮後期主要接替技術之一，火驅過程中原油在地層中高溫燃燒，髮生複雜的物理化學反應，儲層內部會髮生固相、液相、氣相的物化、地化反應，造成巖石礦物溶解、沉澱和蝕變以及油、水組分的變化，進而影響儲層內巖石礦物、孔隙結構、物性流體性質。運用巖石薄片、 X-衍射全巖、鑄體薄片、全烴色譜等十餘項分析測試技術進行研究，揭示蒸汽吞吐轉火驅開髮儲層巖石礦物變化規律，儲層物性變化特徵、孔隙結構變化特點、流體組分變化特徵，為稠油蒸汽吞吐轉火驅開髮儲層變化研究提供瞭較好技術藉鑒。

In-situ combustion, also called combustion drive, is one of replacing technologies after steam injection for heavy oil. During the combustion process, crude oil burns under high temperature, and physical and chemical reactions occur. In the reservoir, physicochemical and geochemical reactions of solid, liquid and gas phase can result in rock dissolution, deposition, alteration and the change of oil and water, which will affect the properties of rock,pore configuration and liquid in the reservoir. In this paper, rock slice, X-diffraction bulk rock analysis, image analysis of cast slice and analysis of physical and chemical properties were utilized to reveal variation mechanism of rock mineral, variation characteristics of physical property in reservoir, variation features of pore configuration and fluid composition in the reservoir with fire-flooding after steam injection.
