塔河油田奥陶系古岩溶洞穴识别及预测
ORDOVICIAN FOSSIL KARST CAVE RESERVOIR RECOGNITION MAKER AND PREDICTION IN TAHE OIL FIELD
【摘要】 在塔河油田奥陶系中蕴藏着丰富的石油资源,碳酸盐岩储层的主要储集空间为裂缝和溶蚀孔、洞,其中岩溶洞穴是最主要的储集空间,研究岩溶洞穴的展布具重要意义.应用钻井、测井、地震等资料分析了岩溶洞穴的识别标志,并利用地震反射结构和振幅变化率技术预测了岩溶洞穴在塔河油田某区的展布.
【Abstract】 There are abundance oil resource in ordovician of Tahe oil field,The main reservoir beds are fracture,corrosive hole and Karst cave, karst cave is the most mostly reservoir,so,researching the distribution of karst cave is very importance.This paper founds the recognition marker of karst cave by using drilling,logging,seismic data,and predicts the distribution of karst cave in some area of Tahe oil field by seismic reflection structure and rate of amplitude technology.This results provide in term of geology science for exploration and development in Tahe oil field.
