针对塔河油田奥陶系碳酸盐岩缝洞型油藏目前储量动用程度低、开发效果变差的特点,以纵向岩溶分带、油井分段开采特征为基础,首次提出缝洞型油藏致密段定义,利用岩心、测井、单井纵向岩溶带分布特征和开发动态特征及地震波阻抗反演等,建立缝洞型油藏高阻致密段划分标准.采用点、线、面相结合技术流程,研究塔河油田6、7区不同致密段分布.该方法已应用到塔河油田开发中,效果较好,成为“十二五”缝洞型油藏精细描述和提高储量动用主要方法之一.
針對塔河油田奧陶繫碳痠鹽巖縫洞型油藏目前儲量動用程度低、開髮效果變差的特點,以縱嚮巖溶分帶、油井分段開採特徵為基礎,首次提齣縫洞型油藏緻密段定義,利用巖心、測井、單井縱嚮巖溶帶分佈特徵和開髮動態特徵及地震波阻抗反縯等,建立縫洞型油藏高阻緻密段劃分標準.採用點、線、麵相結閤技術流程,研究塔河油田6、7區不同緻密段分佈.該方法已應用到塔河油田開髮中,效果較好,成為“十二五”縫洞型油藏精細描述和提高儲量動用主要方法之一.

@@@@For the characteristics that the reserves produced degree and development effect of Ordovician fractured-cavi-ty carbonate rock reservoirs in Tahe oilfield decrease gradually,we use vertical of Karstification and the sublevel develop-ment of Well,first proposed definition of dense layer in fractured-cavity reservoir.And using drilling core,well logging, vertical of Karstification development behavioral characteristics and seismic wave impedance inversion method,estab-lished the distinction criterion of resistive dense layer,studied the distribution of different dense layer in Tahe six&seven district.This technique has been applied to the Tahe Oilfield Development,and it has become one of the most useful meth-ods of fine reservoir description and producing degree of reserves during the current 12th Five-Year Plan.
