将高精度层序解释结果和地震储集层预测技术相结合,在体系域框架下按准层序进行地震属性的储集层预测成图,预测出阿尔金地区的深湖湖底扇沟道浊积砂体有利分布区。湖底扇中扇辫状沟道浊积岩以灰色、灰绿色具粒序砂砾岩、砾状砂岩为主,与半深湖-深湖亚相泥岩伴生。根据预测的砂体,结合构造和生油条件,可以确定勘探岩性油气藏的有利目标。
Combining the results of high-precision sequence interpretation with the prediction techniques of seismic reservoirs, the reservoir properties of the reservoir are predicted and mapped by quasi-sequence in the framework of the system tract. The turbidity at the bottom of the deep lake and the lake in the Altun area is predicted Sand body favorable distribution area. Fan braided trough turbidites in the fan-lacustrine fans are mainly composed of gray, gray-green grained gravel and gravel sandstone and are associated with semi-deep lake-deep lake subfacies mudstones. Based on the predicted sand body, combined structure and oil generation conditions, favorable targets for exploration of lithologic reservoirs can be identified.
