苏德尔特油田兴安岭油层地层精细划分对比研究
Study of the formation fine division and correlation for Xinanlin reservoirs in Sudert Oilfield
【摘要】 通过对苏德尔特油田兴安岭油层复杂沉积体系结构单元的精细研究,综合运用钻井、地质、地震、生产动态等信息,依据层序地层学和储集层沉积学理论,以沉积结构单元分析为基础,在确定单元内井间标志层的条件下,应用测井曲线旋回对比法和沉积微相模式砂体追踪法,完成了井间地层精细划分对比,提高了井间砂体单元横向追踪对比精度,为油藏注水开发提供了准确的地质依据。该方法在实际生产应用中见到了良好的效果,为复杂断块油田精细地层对比开拓了新的研究途径。
【Abstract】 By the fine study for the structural cell of the complex sedimentary system in Xinanlin reservoirs of Sudert Oilfield,synthetically using the information such as drilling,geologic,seismic and productive dynamic,in accordance with the theories of sequence stratigraphy and reservoir sedimentology,on the basis of the analysis for the sedimentary structural cell,the fine division and correlation in the cross-hole formation has achieved under the condition of determining the cross-hole reference lamina within the cell and by using the log cyclic correlation method and the depositional microfacies mode sandbody tracing method.It has improved the accuracy of the horizontal tracing and correlation in the cross-well sandbody cells,thus providing the precious geologic basis for reservoir water injection development.The achievement has obtained a better effect during practical production and opened up a new studying way for the fine formation correlation in complex fault oilfields.
