新疆准噶尔盆地西北缘九区齐古组稠油油藏吞吐后期剩余油分布研究

A Study of the Remaining Oil of Distribution in late Development of Shallow Heavy Oil

本文根据大量现场资料 ,立足于生产实际 ,针对准噶尔盆地西北缘典型的稠油油藏克拉玛依油田九区齐古组 ,并重点解剖了九 5试验区 ,运用密闭取心、生产测试、动态分析、开发地震、数值模拟、随机模拟、开发地质分析等方法 ,总结了稠油水淹层特征 ,建立了一种稠油水淹层测井解释模型 ,分析了各种剩余油研究方法的评价效果。由点到面 ,由定性到定量 ,进一步认识了井间、平面、纵向的剩余油分布规律。该项研究成果有助于稠油油藏开发中后期油藏的调整、加密及改善注蒸汽热采效果 。

According to the amount of field matericals,aiming to the typical heavy oil reservoir of Qigu group in region 9 in Karamay oilfield of Xibeiyuan in Junga'ar basin and emphasising on pilot area jiu 5,using the methods of sealing core drilling,production test,performance analysis,and development seismic,numerical simulation ,stochastic simulation and development geologic analysis and summarizing the characteristic of heavy oil water-out reservoir,the article established a type of logging interpretation model of heavy oil reservoir and evaluating the effect of various methods of remaining oil.The remaining oil distribution between wells,in horizontal and vertical direction is understood, gained from one unit and popularizing a whole area,and from qualitative analysis to quatitative analysis.The results is helpful to the adjustment, infill and the improvement the effectiveness of thermal recovery ,and afford experiences and basis for the thermal recovery of same types of reservoirs.
