东辛油田营14复杂断块油藏构造建模技术应用
|
摘要
东辛油田古近系断裂破碎,构造复杂,主要油藏类型为复杂断块油藏。复杂断块油藏是一种重要的隐蔽油气藏类型,在陆相断陷盆地中占有很大的储量份额,也是老油区挖潜增储的重要目标,然而这种油藏面积较小,隐蔽性强,识别与描述非常困难。以东辛油田营14断块为例,在地质资料分析的基础上,以地震资料解释及合成地震记录标定结果为约束条件,采用相干分析、构造特征分析等技术手段进行研究,建立了油藏精细构造模型。该模型提高了构造解释的精度和准确性,为后续的油藏地质建模提供了高精度的边界约束数据。

<br> For the Early Teriary in Dongxin oilfield, there are complex geologic conditions due to complicated faults. The complicated fault-block reservoir is an important anthydrocarbon reservoir, which account for considerable proportion in continental rift basin at present, and also which becomes the primary production aim. But they are very difficult to distinguish and describe as their complicated and subtle in structure. Based on analysis of geological data of Yingl4 fault-block in Dongxin oilfield, fine structural model of oil reservoir was established with constrained conditions of interpretation of seismic data and calibration of synthetic seismogram and techniques of coherent analysis and structure character analysis. It developed the accuracy degree and veracity of structure interpreting. The result provided refined boundary constraints for the sequent geologic modeling of reservoir.
