扇三角洲岩性油气藏储层描述技术研究——以营子街地区为例
|
摘要
制约深洼区隐蔽性岩性油气藏勘探开发的因素较多,其中准确描述储层空间展布特征是主要因素。以营子街地区为例,通过对该区地震相的精细划分以及砂体的识别描述研究,形成了扇三角洲岩性油气藏储层描述"五步法"技术,包括拓频处理识储层、地震响应明特征、地震相分析定区带、测井约束反演定目标、分频属性圈边界。勘探实践表明,该项技术具有良好的应用效果,可建立不同类型砂体的地震波形识别模式及砂体横向接触关系,并可明确前缘亚相、前三角洲亚相的地震特征。利用该项技术预测了洼陷带岩性油气藏有利发育区,为勘探部署提供了可靠依据。
There are many factors restrict the exploration and development of subtle reservoir in the deep lake area. The accurate description of reservoir distribution is the important factors of oil and gas exploration and development. Taking the exploration in Yingzijie area as an example, through the research of seismic facies division and sand body identification, we formed the"five steps"method for reservoir description of lithologic reservoirs in fan delta, which includes using seismic frequency extension to identify reservoir, using seismic response to show characteristics, using seismic facies to define zones, using muti-well joint constrained inversion to determine fine sand bodies and using frequency divider to interpret boundary. The exploration practice shows that this technology has good effect, and can be used to establish models of seismic wave form for different type of sand bodies, show the contact relationship of crosswise sand, confirm the facies configuration of delta front and prodelta, and predict favorable zones of lithologic reservoir.
