摘要： 准噶尔 盆地白垩系油气藏具有孔隙度、渗透率高,地层水矿化度、压力系数和电阻率低等低电阻率油气藏的基本特征。对典型储集层测井资料的分析和电阻率测井响应理论模拟表明,白垩系低阻油气藏钻井液侵入主要发生在打开油气层的初期,并以钻井液的“喷失”侵入为主,及时测井对于改善油气、水层的识别效果不明显。感应测井与侧向测井的对比测量结果表明,油气层、水层的深、浅感应测井电阻率差异特征显著,油气层感应测井电阻率高于侧向测井电阻率,水层感应测井电阻率则小于侧向测井电阻率。在快速识别白垩系低阻油气层和水层的效果上,感应测井明显优于侧向测井。根据新疆油田公司测井技术装备现状,分别制订并实施了低阻油气藏预探井、评价井和生产井三种测井.系列,提高了勘探开发效益,地质效果明显。

Abstract: The Cretaceous low resistivity reservoir in Junggar basin is characterized by high porosity, high permeability, low salinity of formation water, low formation pressure and low resistivity. Based upon the analysis of log curves and the simulated log responses of formation, it was demonstrated that the filtrate invasion to Cretaceous low resistivity reservoir mainly occurred during the very beginning of the penetration of the permeable formation. Logging immediately made after drilling has not much improvement to the identification of pay zone. It was verified that induction logging is superior to lateral logging by comparing those two measurements in various wells. Three kinds of logging suites are successfully carried into execution in the exploration and development of the Cretaceous low resestivity reservoir in Junggar basin.

Key words: low resistitvity reservoir, mud filtrate invasion, induction logging, laterolog, hydrocarbon identification, Junggar basin
