东营凹陷永安地区地震反演及储层预测
|
摘要
东营凹陷永安地区的油气勘探主要目的层是古近系沙河街组二段和三段,沉积环境为三角洲相和滨浅湖相,其中砂岩储层具有较好的成藏条件。但是,复杂的断裂系统造成的强烈改造增加了井间地层对比和储层预测的难度。针对东营凹陷永安地区目的层的地质情况,在准确层位标定的基础上,通过精细构造解释、构造地质建模、多井约束反演和储层预测等工作,结合钻井资料,建立了储层厚度与反演阻抗之间的关系模型,预测了储层分布范围。根据地震反演预测的沙河街组三段中亚段浊积砂体经钻探获得了油气发现,扩大了研究区油气滚动勘探开发的范围,对整个东营北带的油气勘探具有参考意义。
In Dongying Sag,the main formation for oil and gas is the second and third member of Shahejie formation of Paleogene.The sedimentary environment is mainly of delta,shallow lake and shore subface, in which,the sand reservoir has good condition for hydrocarbon accumulation,but the serious reconstruction caused by complex fault system increases the difficulty of stratigraphic correlation between wells and reservoir prediction.Seismic predicting technique integrates the advantages of interpretation and inversion software, aiming at the geologic conditions of the target intervals in Yongan area of Dongying Sag,based on accurate formation calibration,by fine structure interpretation,structural geological modeling,multi-well constraint inversion and sandstone reservoir prediction,combined with drilling data,the relationship model between reservoir thickness and inversed impedance was established,and the distribution of reservoirs was calculated.The turbidite sandbody,being predicted in the middle section of the third member of Shahejie formation by inversed seismic data,has obtained oil by drilling.The discovery extends the scope of oil and gas in Yongan area,and is important to the whole north part of Dongying Sag.
