提出了一套利用常规测井资料在地质条件约束下,动静态相结合、岩心刻度、多学科联合下,先对水淹层水淹级别进行划分,然后,在地质条件约束的水淹层测井评价模型基础上,对水淹层水淹级别进行由定性识别到定量判别再到定量评价的水淹层测井评价方法。利用该方法对孤岛油田中一区Ng3+4高孔、高渗河流相储层510口井的水淹层常规测井资料进行了处理和评价,经动、静态资料误差检验,证明该方法能较大幅度地提高水淹层测井评价精度。经现场8口新井检验,该方法的水淹层测井评价精度比常规其它水淹层测井评价方法的评价精度提高25倍以上,其评价结果能够满足实际生产需要。
In this paper, a set of conventional well logging data using the combination of dynamic and static conditions under the constraints of geological conditions, core scale, multidisciplinary joint, the water flooded layer flooding level is divided first, and then, in the geological conditions of the water flooded layer measurement Based on the well evaluation model, the method of water flooded bed logging evaluation from qualitative identification to quantitative discrimination to quantitative evaluation of water flooded layer flooding levels is presented. The conventional logging data of waterflooded layer in 510 wells of Ng3 + 4 high porosity and high permeability fluvial facies in Gudao Oilfield were processed and evaluated. The error of dynamic and static data verifies that this method can be applied to large Improve the logging evaluation accuracy of the flooded layer in a range of ways. According to the field test of eight new wells, the accuracy of the method of water flooded bed logging evaluation is 25 times higher than that of conventional other water flooded bed logging evaluation methods, and the evaluation results can meet the actual production needs.
