摘要

摘要: 大量研究已经证明,将干酪根生烃热模拟实验结果直接应用于含油气盆地烃源岩评价存在很大风险性。生烃动力学方法可将实验生烃数据外推地质过程,因而具有较高的应用价值。本研究采用金管高压釜封闭体系对渤海湾盆地东营凹陷1块Es⁴⁽²⁾褐色页岩进行了生烃动力学研究,对热模拟产物4种组成C₁、C_1-5、C_6-12及C₁₃⁺生成动力学参数,采用Kinetics动力学软件进行计算,并模拟了具体地质条件下的成烃规律。将本研究结果与早期研究结果以及实际地质资料进行了对比,结果表明,烃源岩生烃动力学模型可较好吻合地质条件下生烃过程,在油气勘探中具有广泛应用前景。

Abstract: Lot of research work has shown that great risk will be introduced by a direct use of thermal simulation of petroleum generation pattern of a source rock. Kinetics method of hydrocarbon generation can be used to exptrapolation of the kinetics of oil and gas formation from laboratory experiments to sedimentary basins. Thus, the data obtained by this method are greater valuable for source rock evaluation. In this paper, the petroleum generation pattern of kerogen of the Lower Tertiary brown black shale from the Dong-ying Depression was studied using a golden tube-high pressure stove, and the petroleum generation kine-tics parameters of the kerogen for the four group compositions of C₁,C_1-5,C_6-12 and C₁₃⁺ were deduced by a patented software Kinetics. A comparison was made between this result and the geological data, showing that petroleum generation model obtained by this method can match with petroleum generation pattern of the source rocks in geological conditions. The kinetics method of petroleum generation will have wide application in source rock evaluation.
