RMS提取技术在溶洞型碳酸盐岩储层地质建模中的应用
|
摘要
三维地质建模在油气田的开发过程中发挥着越来越重要的作用。在碎屑岩储层的应用中已经形成一套较为成熟、效果良好的方法技术,但是在碳酸盐岩储层预测的应用中尚处于探索阶段。应用PETREL储层建模软件,以地震属性RMS提取技术为建模核心方法,建立塔河4区碳酸盐岩溶洞的分布模型,并且对塔河4区实际洞穴与此模型预测结果进行对比统计,72个样点中吻合的有54个,吻合率为75%,较为准确的再现塔河4区地下空间分布,此模型可为以后的勘探开发提供有效依据。
Three-dimensional geological molding(3D-GM) is getting more and more important in the oil-gas field exploration.The utility of 3D-GM in the detrital reservoirs is mature and efficient;however,in the carbonate reservoirs,it still lies in the exploratory stage.With the developing of the geophysical technique and its extensive using in the research of petroleum geology,people become aware of the practicality of the seismic technology.In this article,authors use PETREL reservoir modeling software,adopting the RMS seismic attributes extraction technology as the core modeling method,to establish the distribution model of carbonate cavities.A contrast between the real and the predicted caves shows that 54 out of 72 predicted data inosculate the real ones.The coincidence rate is 75%.The model precisely reconstructs the Tahe-4 region's underground directional distribution and provides a valid reference for the subsequent exploration.
