测井资料在水淹层投产方案优化中的应用

Application of Logging data in Production Scheme Optimization for Water-Flooded Reservoirs

扶余油田历经40多年的开发,已经进入高含水中后期,而扶余油田油层多属于正韵律油层,通过研究明确了其水淹特征规律,水淹特征规律是新井投产方案优化的重要依据。投产方案优化是在对油藏地质特征及产能调整方案目的认识比较清楚的基础上,主要利用新井的测井曲线进行投产选层,并结合邻井的各种静、动态资料对新井的射孔井段、改造方式和规模进行合理的优化,也是实现油藏设计目的达到新井预计产能及效果的保障,结合扶余油田具体情况分四类井探讨测井曲线在制定新井投产方案中的应用。

Fuyu oilfield has gotten into the stage of high water cut after more than 40 years of development,and the oil layers are belong to positive rhythm quite a lot.We has made clearly the law of water flooded characteristics which is the important basis of the production scheme optimization.First,we need to understand clearly the geologic characteristics of the reservoir and the aim of the production capacity adjustment scheme.Then we use logging data to select the layer.At the same time,combining with all the kinds of static and dynamic data from offset well to optimize rational perforated interval.Transformation methods and the scale and the optimization is the security to realize the purpose of reservoir plan and achieve the estimate production capacity of new well.The article will discuss the application of logging curve in formulating the scheme of the new-well putting into production in four types wells,which combines with specific situation in Fuyu oilfield.
