Low Amplitude Thin Edge And Bottom Water Reservoir Remaining Oil Distribution And Its Application

According to the domestic water development experience, oilfield waterflood development phase in which high water improves waterflood recovery urgent requirement, which requires distribution of remaining oil in-depth study, in order to build an expanded range of water flooding the injection patterns, so as to achieve the purpose of improving water flooding recovery.The object of this thesis is Luliang Lu9wellblock Hutubihe Formation reservoir, the reservoir is low amplitude thin edge and bottom water reservoir, all the main reservoir in high water has entered the stage, still no comparison the remaining oil distribution system of research and development at home and abroad have been no similar reservoirs reservoirs can provide a reference. This thesis on the development characteristics of reservoir geology basically, using conventional logging, special logging techniques for reservoir383through the drilling of wells flooded real thickness, location identification and numerical simulation methods comprehensive research and analysis, have out of the reservoir can be well described waterflooding and remaining oil distribution. In the numerical simulation based on the adjustment of the reservoir by way of a post-optimization analysis, obtained distribution of remaining oil to adapt the best adjustment mode.The papers of well group numerical simulation shows the remaining oil distribution obtained with conventional logging identification rules are basically the same, and the reservoir in2008, after some sporadic infill mining results also confirmed in this study reliability of the results.
