塔河油田碳酸盐岩储集层地球物理识别模式

塔河油田碳酸盐岩储集层埋藏较深，一般都在5300m以下，储集层主要为碳酸盐岩裂缝和溶蚀缝洞系统，纵横向非均质性强，储集层横向预测困难，通过大量的钻井，岩心，测井，地震资料对比分析，探讨并建立了超深层碳酸盐岩储集层的地球物理识别模式，为碳酸盐岩储集层的识别和预测提供了科学依据，成为塔河油田勘探开发的技术支持。

Geophysical Recognition Model for Carbonate Reservoir in Tahe Oilfield

Tahe oilfield's carbonate reservoir is buried deeply with normal depth over-5300m.The dominated system of carbonate fractures and corrosive caverns and serious heterogeneity in plane and vertical results in difficulty for transverse prediction of the reservoir distribution.This paper correlated and analyzed a lot of drilling,coring,well logging and seismic data,discussed and developed a geophysical recognizing model for extra-deep carbonate reservoirs,which gives a great support to exploration and development of Tahe oilfield by means of such a more practical model for carbonate reservoir recognition and prediction.
