摘要:
生烃凹陷的烃源条件与资源潜力评价是盆地油气勘探的重要基础。烃源岩地球化学评价法难以揭示生烃凹陷全貌特征，生烃量与资源量直接计算法通常难以适用于低勘探程度区。提出烃源指数的新指标，将其定义为快速评估生烃凹陷油气资源数量的量化指标，并从凹陷体积与烃源岩质量两方面提取关键参数加以定量表征。其具体取凹陷面积、凹陷源岩层最大厚度表征凹陷体积，取地层沉积相、干酪根类型与凹陷最大埋深表征烃源岩质量。计算了高勘探区珠江口盆地惠州凹陷12个洼陷文昌组的烃源指数，并基于“源控论”与黑箱原则，建立了烃源指数与成因体积法计算的资源量之间的乘幂关系。经另一高勘探区渤海湾盆地东营凹陷的检验，由烃源指数估算的资源量是可信的。应用烃源指数快速评价了低勘探区恩平凹陷，得出EP17、EP18和EP12等3个洼陷文昌组总资源量达13.193×108 t，并认为恩平凹陷属于富烃凹陷，其中EP17洼烃源条件最优，为富生烃洼陷。烃源指数涵盖了凹陷体积与源岩质量两方面信息，涉及参数少且易获取，适用于生烃凹陷资源潜力的快速评价，尤其是低勘探区。
Abstract:
The evaluation of hydrocarbon source condition and resource potential for hydrocarbon-generating depression is the essential foundation of petroleum exploration in petroliferous basin. The quality of source rock could be assessed by common geochemical experiments of samples effectively, but the character of the whole depression can not be revealed. The depression can be evaluated by direct calculation of resource quantity, which needs lots of data, so it is unsuitable in low level exploration area. A new parameter, the index of hydrocarbon source (IHS), was proposed. IHS is defined as a numerical index assessing the hydrocarbon quantity provided in a depression, and it is calculated by depression area, maximum thickness of source bed, sediment facies, kerogen type and maximum depth. The IHSs of twelve sags in Wenchang Formation of Huizhou depression, Pearl River Mouth Basin were calculated, and the power correlation between IHS and resource quantity calculated by genetic volume method was built based on “source-controlled theory” and black box. This relationship is verified fine in Dongying depression of Bohai Bay Basin. IHS was used to quickly evaluate the resource potential for Enping depression with low exploration. The results show that the total resource quantity of EP17, EP18 and EP12 sags is 13.193×108 t, and Enping depression is rich in hydrocarbon; the hydrocarbon source condition of EP17 sag is best and rich. As a new parameter, IHS includes the information of both depression volume and source rock quality, and the parameters for calculating IHS are common and accessible, so it is useful to rapidly evaluate the resource potential of depressions, especially the low level exploration areas.
