塔河2区奥陶系油藏剩余油分布主要受断裂、古水系、连通性、构造、采出程度、水淹状况等因素控制,通过对主干断裂的精细描述,分析储集体展布方向及控制因素,利用多种动态分析方法对连通性进行综合分析,并对油井纵向和平面上的水淹状况进行分析,明确水淹进程,得出剩余油分布特征及模式。针对不同的剩余油分布模式采取不同的治理对策,改善开发效果。
塔河2區奧陶繫油藏剩餘油分佈主要受斷裂、古水繫、連通性、構造、採齣程度、水淹狀況等因素控製,通過對主榦斷裂的精細描述,分析儲集體展佈方嚮及控製因素,利用多種動態分析方法對連通性進行綜閤分析,併對油井縱嚮和平麵上的水淹狀況進行分析,明確水淹進程,得齣剩餘油分佈特徵及模式。針對不同的剩餘油分佈模式採取不同的治理對策,改善開髮效果。

Ordovician reservoir in the second block of the Tahe oil field is mainly controlled by faults,ancient water sys-tem,connectivity,structure,recovery percent of reserves,water flushed characteristic and other factors.Analysis of reser-voir distribution and control factors are through the fine description of the main fault;using a variety of dynamic analysis method is to make a comprehensive analysis of the connectivity;Based on reservoir distribution and connectivity,analyse of watered-out vertical and lateral wells,clear water flooding process,Summarize the distribution of remaining oil.The dif-ferent treatment countermeasure taken in view of the different mode of residual oil distribution is to improve the develop-ment effect .
