摘　　要：随着鄂尔多斯盆地南缘致密油成藏机理与富集规律认识的不断深入,镇泾、彬长等区块断缝体油藏相继取得突破。但由于鄂南断缝体多为走滑断层,断距较小,其地震同相轴仅有微弱的扭曲,导致小于10 m断距的断裂在物探剖面中较难识别。通过对镇泾、彬长区块断缝体油藏成藏机理和富集规律分析,开展了断裂体系发育特征研究,厘清了断缝体油藏成藏主控因素和富集规律,确定了断缝体储层类型及其测录井响应特征,并形成了一套致密油断缝体储层测录井评价技术,可为区内断缝体油藏评价和开发提供技术支撑。With the continuous deep understanding of the formation mechanism and enrichment law of tight oil reservoirs in in the southern edge of the Ordos Basin,breakthroughs have been made in fractured reservoirs in blocks such as Zhenjing and Binchang blocks.However,because most of the fault joints in southern Hubei are strike-slip faults with small fault distance,the seismic in-phase axis is only weakly distorted,which makes the faults with fault distance less than 10 m difficult to identify in the geophysical profiles.Based on the analysis of reservoir formation mechanism and enrichment law of faulted fracture reservoir in Zhenjing and Binchang blocks,the development characteristics of fault system were studied,the main controlling factors of reservoir formation and enrichment law of faulted fracture reservoir were clarified,the types of faulted fracture reservoir and their logging response characteristics were determined,and then a set of tight oil faulted fracture reservoir logging evaluation technology was formed.It can provide technical support for the evaluation and development of fractured reservoir in the region.
