渤深6下古生界潜山碳酸盐岩储层预测研究
|
摘要
渤深6潜山油藏的目的层为下古生界奥陶系碳酸盐岩地层,埋藏较深,内部断层和缝洞较发育,地震资料品质较差,而且完钻井少,因此,难以准确预测储层的纵向及平面展布规律。为此,利用相干分析、振幅属性分析、测井约束反演和多尺度边缘检测等技术,对渤深6潜山有利储层发育区进行了预测,并对预测结果进行了综合评价。利用多参数聚类分析技术进行了储层含油气性评价,认为渤深6区块大面积含油。将预测结果应用于井位设计,部署的4口井均获得了高产油气流。
The target bed of Block Boshen 6 is Ordovician carbonate reservoir of lower Palaeozoic. It is deeply buried with a few drilled wells, seismic data of poor reflection quality, complex development law and obvious heterogeneity. It is difficult to determine its distribution rule whether vertically or horizontally. So do research reservoir prediction, many new technologies such as coherent analyses, amplitude attribute analyses, inversion restrained by logging and multi-scales marginal detection etc. are adopted so that favorable growth area of Boshen 6 buried hill are de-script exactly, which can result in increasing of the accuracy of designed well location, reducing of the risk of progressive exploration and speeding up of productivity construction. Based on comprehensive evaluation result of reservoir prediction. 3 E&P progressive wells are deployed with good application effects.
