【摘要】：针对马头营凸起馆陶组低幅度构造落实程度低、储层预测难度大和成藏规律认识不清的难题,通过等效Q补偿高分辨率处理技术,提高地震资料主频分辨率,目的层段地震资料主频由30 Hz升至40 Hz;采用层控网格层析速度建模,提高速度求取精度,准确落实低幅度构造圈闭;利用属性分析技术进行沉积相分析,精细刻画目的层段河道砂体展布,并结合原油生物标志化合物对比、油气输导体系、油藏主控因素分析,明确了马头营凸起馆陶组的控藏要素,精细刻画了各成藏要素之间的时空配置关系,重建了马头营凸起馆陶组的油藏模式。预测了有利的油气聚集区,通过勘探部署,取得了良好的钻探效果,并形成了一套针对浅层低幅度构造油藏的精细评价技术和方法。该研究可为冀东油区周边凸起及渤海湾盆地相似地质条件下低幅度构造油藏的勘探提供借鉴。
[Abstract]:In view of the difficulties of low amplitude structure implementation, high difficulty in reservoir prediction and unclear understanding of reservoir forming law in Guantao formation of Matouying uplift, the main frequency resolution of seismic data can be improved by equivalent Q compensation high resolution processing technology.The main frequency of seismic data in the target interval increases from 30 Hz to 40 Hz, the velocity modeling of stratified grid tomography is used to improve the accuracy of velocity calculation, and the low amplitude structural traps are accurately implemented. The sedimentary facies are analyzed by attribute analysis technique.The distribution of river channel sand bodies in the target formation is described in detail. Combined with the correlation of crude oil biomarkers, oil and gas transport system, and the analysis of main reservoir control factors, the reservoir control elements of the Guantao formation in the Matouying uplift are determined.The spatiotemporal distribution of the reservoir elements is described in detail, and the reservoir model of the Matouying uplift Guantao formation is reconstructed.A favorable oil and gas accumulation area is predicted and a set of fine evaluation techniques and methods for shallow low amplitude structural reservoirs are developed through exploration and deployment.This study can be used as a reference for the exploration of low amplitude structural reservoirs in the peripheral uplift of Jidong oil area and the similar geological conditions in the Bohai Bay basin.
