摘　　要：文明寨油田是一个埋藏浅、油层多、非均质严重的层状中高渗透极复杂断块油藏。为增加动用储量,运用高精度碳氧比测井技术,开展剩余油分布研究,通过生产层水淹程度分析,对未射孔储层进行含油性评价。应用结果表明,该技术可以确定剩余油分布,寻找潜力层,提高Ⅱ,Ⅲ类层动用程度。该技术为薄油层、差油层及未分层的地层含油性评价,以及改善油藏整体调治效果,提供了有力的技术支持,对进入中高含水期后的类似中高渗复杂断块油藏剩余油挖潜具有借鉴意义。Wenmingzhai Oilfield is a very complex fault-block oil reservoir with shallow depth,multiple zone,serious heterogeneity,medium and high permeability.In order to increase the producing reserves,this paper studies the distribution of remaining oil,analyzes the watering-out degrees of pay horizons and evaluates the oil-bearing ability of not perforated reservoir by using high-precision C/O ratio spectrum logging technology.Application practices show that this technology can determine the distribution of remaining oil and find the potential layer.It can provide strong technical support for improving the whole effect of adjustment and government for reservoir,increasing the producing degree of TypeⅡand Ⅲ layers and evaluating the oil-bearing ability of thin and poor oil layers and not layered formation.It has certain reference significance for the potential tapping of remaining oil from the similar complex and medium permeability fault-block oil reservoir at mid to high water-cut stage.
