摘要(Abstract)：

针对大庆长垣外围油田低渗透储层“砂体窄薄、油水识别难、裂缝动态演化复杂”的难题，基于“四分法”构建低阻油层识别图版，采用井震结合波形指示反演与密井网地质模式约束结合，精细刻画三角洲前缘分类储层单砂体，基于四维应力场模拟建立体现开发全过程的“动态缝”建模数模一体化技术。结果表明：葡萄花油层低饱和度油层识别新图版判别准确率提高了5.1百分点，井震结合窄薄河道砂预测精度达83.3%，明确河道砂体4类组合模式及席状砂3大类5亚类单砂体成因及分布模式，“动态缝”建模数模一体化模拟单井符合率提高了12.5百分点，实现开发过程中裂缝有效性的动态量化，精准定位剩余油富集区。研究成果为长垣外围高含水期油田灵活加密调整和精准挖潜提供了理论基础。
Facing the challenges of“ narrow and thin sandbodies, difficult identification of oil and water layers, and complex dynamic fractures evolution” in peripheral oilfield of Daqing Placanticline, low-resistivity reservoir identification chart is established based on “four-division method”. Well-seismic waveform indication inversion and dense well pattern geological model constraints are combined to finely characterize individual sandbodies in classified delta front reservoirs. Integrated “dynamic fractures” modeling and numerical simulation technique is established based on four-dimensional stress field simulation to reflect entire development process. The results show that new chart for low saturation oil layers in Putaohua reservoir increases identification accuracy by 5.1 percentage points, and well-seismic integrated prediction accuracy of narrow and thin channel sands reaches 83.3%. 4 types of channel sandbodies assemblage patterns are clarified and genesis and distribution patterns of 5 sub-types of individual sand bodies in 3 major types of sheet sand are determined. Integrated dynamic fractures modeling and numerical simulation technique increases single-well coincidence rate by 12.5 percentage points, achieving effective dynamic quantitative evaluation of fractures during development process and precise localization of remaining oil enrichment areas. The research provides theoretical foundation for flexible infilling adjustments and precise potential tapping in high water-cut stage of peripheral oilfield of Placanticline.
