开发地震技术在扶余油层分支水平井地质设计中的应用
|
摘要
大庆外围东部油田开发的目的层主要为葡萄花油层和扶余油层,其中扶余油层因储层发育差,具有低孔、低渗、低丰度的特点,其未动用储量的有效开发一直是困扰油田开发的难题之一。要应用开发地震技术,结合钻井、测井、试油、沉积相等资料,通过细致描绘肇州油田芳483区块扶余油层的构造特征,预测扶余油层内部单砂体的分布形态、厚度和展布范围,为扶余油层分支水平井设计提供地质依据,同时也为有效开发扶余油层探索了新的思路。
The Fuyu oil layer in eastern oilfields of periphery Daqing is poorly developed with lower porosity,low permeability and abundance.The effectively production has been puzzled for many years. The production seismology combined with drilling,logging,oil testing and sedimentary facies has been used to delineate structure characteristics of Fuyu oil layer in Fang 348 block of Zhaozhou oilfield.The extended formation,thickness and spatial area about single sandstone inside the layer are then predicted,which provides geological support about branched horizontal well design of Fuyu oil layer. This method also explores a new idea about effective development of Fuyu oil layer.
