储量是指在地层原始条件下的油气量。地下的油气存在于不同类型的砂岩颗粒孔隙或地层的裂缝、孔洞中,不同组分的油气又有不同的物理、化学性质。由于油气藏的类型(条件)不同、驱动类型(能量)不同,从而开采出的量就有所不同。许多因素,如开发方式的好坏、开采工艺技术的高低等,都会极大地影响采收率。对于油藏来讲,一般水压驱动油藏的采收率为30%～50%,气顶驱动油藏的采收率为20%～40%,溶解气驱动油藏的采收率为
Reserve refers to the amount of oil and gas in the original conditions of the formation. Underground oil and gas exist in different types of sandstone pores or formation cracks, holes, different components of oil and gas have different physical and chemical properties. Due to the different reservoir types (conditions) and the different drive types (energy), the amount recovered is different. Many factors, such as the quality of development methods, the level of mining technology, etc., will greatly affect oil recovery. For reservoirs, the recovery rate of typical hydraulically driven reservoirs is 30% -50%, that of gas-driven reservoirs is 20% -40%, and that of dissolved gas-driven reservoirs is
