深层烃源岩成烃理论研究进展

老油区深层具有很大的勘探潜力，深层烃源岩油气生成理论是寻找深层油气藏的基础，目前的研究表明，深层油气藏的温度已超出传统的干酷根晚期成油理论所认为的“液态窗”，深层烃源岩仍具有较高的有机碳含量，是深层油气藏的物质基础，温度和压力是影响有机质生烃演化的主要因素，目前较多的实验数据和勘探发现证明，压力可延迟或抑制油气生成和有机质成熟，中国东部深层具有巨大的勘探潜力，但仍需要深入研究深层烃源岩生烃理论，深层储层的储集性能，高温高压条件下的油气成藏和深层油气勘探技术等问题。

Progress in theory of hydrocarbon generation in deep source rocks

There is a big potential of exploration in deep formation of mature oil province. Theory of hydrocarbon generation in deep source rock is the base of finding deep reservoirs. Present research work shows that, temperature of deep reservoirs exceeds the "liquid window" depicted by traditional theory of oil generating in late kerogen period, the content of organic carbon is still high in deep source rocks, and it is the material basis of forming deep reservoirs. Temperature and pressure were main factors affecting hydrocarbon evolution. Many experiment data and exploration discoveries have proved that, hydrocarbon generation and organic maturity may be delayed and inhibited by pressure. There is great potential in deep formation of east China, yet further study is needed for hydrocarbon generation theory of deep source rock, properties of deep reservoirs, reservoir forming conditions under high temperature and pressure, and deep reservoir exploration technique.
