南黄海崂山隆起下石炭统和州组至下二叠统栖霞组储层预测

RESERVOIR PREDICTION FOR DEPOSITS FROM HEZHOU FORMATION OF LOWER CARBONIFEROUS TO QIXIA FORMATION OF LOWER PERMIAN ON THE LAOSHAN UPLIFT OF THE SOUTH YELLOW SEA

以叠前时间偏移地震资料为基础,采用相干体、蚂蚁体和储层综合响应的物性因子方法针对勘探程度较低的南黄海崂山隆起下石炭统和州组至下二叠统栖霞组碳酸盐岩进行储层预测。相干体、蚂蚁体预测结果表明,和州组至栖霞组发育多套储层,栖霞组储层裂缝发育和分布受断裂和构造挤压变形控制强烈,北部断裂带和南部挤压背斜区裂缝较为发育。储层综合响应的物性因子预测结果显示,和州组至栖霞组在南部地区的有利储层发育,主要集中在挤压背斜发育区和沿断裂带发育区。该储层的预测结果为崂山隆起有利目标区的评价提供了地质依据,同时该方法的应用对于南黄海的油气勘探具有重要的指导意义。

Upon the basis of prestack time migration seismic data,coherent body,ant body and reservoir physical factors are applied to make reservoir prediction for the deposits from the Hezhou Formation of Lower Carboniferous to the Qixia Formation of the lower Permian at the Laoshan Uplift of the South Yellow Sea.Prediction results show that there are several sets of reservoirs in the studied sequence.Reservoir cracks are developed and distributed under the control of faults and tectonic extrusive deformation.There are more cracks in the northern fault zone and southern extrusive zone.The prediction based on the integrated response of reservoir shows that the most favorable reservoir is developed in the southern part of the uplift,mainly concentrated in the extrusive anticline zones and fault zones.The reservoir prediction results have provided a strong geological basis for the evaluation of the Laoshan Uplift and favorable target areas,and the methods used in the case are proven effective.
