地震和测井联合反演技术在塔河油田碳酸盐岩储层预测中的应用

Application of seismic and logging joint inversion in the prediction of carbonate reservoirs in Tahe oilfield

碳酸盐岩储层预测一直为一世界性难题。基于引进软件Jason的方法原理 ,针对塔河油田奥陶系碳酸盐岩储层以岩溶、构造运动形成的溶蚀孔洞和裂缝系统为主 ,埋藏深 ,非均质性强的特点 ,探索出了一套适合塔河油田奥陶系碳酸盐岩储层预测的地震、测井联合反演流程 ,提高了碳酸盐岩储层预测的可靠性 。

Prediction of carbonate reservoirs is a cosmopolitan problem. Seeing that the Ordovician carbonate reservoirs in Tahe oilfield are dominated by vugs and fracture systems caused by karstification and tectonic movement, and characterized by deep bury and strong heterogeneity, this paper proposes to apply seismic and logging joint inversion to the prediction of carbonate reservoirs. Desired results with improved reliability have reached.
