黄场斜坡带岩性油藏极其发育,通过开展构造精细解释、沉积微相以及砂体展布特征的研究,认为黄场斜坡带构造和砂体空间配置较好,极易形成上倾尖灭型岩性圈闭,并划分出该区岩性圈闭发育的范围;然后利用地震储层预测技术和岩性圈闭识别方法,预测出该区的岩性圈闭;最后通过对这些岩性圈闭进行地质综合评价研究,对发现的岩性圈闭进行含油气性预测。预测与实钻结果吻合较好,钻探成功率高达60%。同时,总结出一套典型盐湖地区预测岩性油藏的系统研究方案,在同类盆地中有推广应用价值。
Through the study of fine structure interpretation, sedimentary microfacies and distribution characteristics of sand bodies, the lithology reservoirs in the Yellow Slope and the slope are extremely well developed. It is considered that the Yellow Earth slope belt structure and sand body space configuration are good, Type lithologic traps and divide the range of lithologic trap development in this area. Then, using the method of seismic reservoir prediction and lithologic traps identification, the lithologic traps of this area are forecasted. Finally, Traps to conduct a comprehensive geological evaluation of the discovery of lithological traps containing oil and gas prediction. The prediction is in good agreement with the real drilling result, with a drilling success rate of up to 60%. At the same time, a set of typical systematic research programs for predicting lithologic reservoirs in the Salt Lake region is summarized, which has the value of popularization and application in similar basins.
