Combining the domestic and abroad researches , several sets of comprehensive models evaluating the - type oil reservoir heterogeneity were built by applying the geological empirical formulae and theory of mathematics statistics . the evaluating principle and process of these methods were also described in detail . owing to the geological information of research target , the application of each model was also discussed in the end 综合国内外成果，应用地质经验公式和数理统计理论，建立了多套二类油层综合评价模型，详细阐述了各模型的原理和评价过程，根据研究区地质资料，讨论了各模型的适用状况。
Based on the development feature analysis , this paper studies thoroughly the reservoir flood feature and remaining oil distribution through the microstructure , sendimentary phase , reservoir heterogeneity and well control , and proposes the comprehensive adjustment based on the injection and development well net structure and improvement the result of the research is obvious with the production degression rate from 9 . 14 % of 1997 to present - 1 . 46 % , and water rate from original 0 . 33 % to present 0 . 16 % . in summary , the research idea , method and new achievement of the thesis provide a scientific geological basis for the oilfield development improvement 在对本区开发历程和开采特征分析的基础上，从微构造、沉积微相、储层非均质性、井网控制等方面深入地分析了油藏水淹特征及剩余油分布规律，提出了以完善注采井网、调整注采结构为目的的综合调整措施，已见到了明显的效果：油田递减由1997年的9 . 14降至目前的- 1 . 46 ，综合含水上升率由原来的0 . 33降至目前的0 . 16 。
