摘　　要：针对大庆外围油田仅根据储层厚度识别难压层存在的不足,通过对A区块葡萄花层可能影响破裂压力高低的储层厚度、岩性特征等10项参数,先进行单因素、归一化、关联度量化分析,明确影响储层破裂压力的主要参数;再通过对主要参数综合评价分析,建立了葡萄花层难压层识别方法,并以此方法对邻近B区块等葡萄花难压层进行识别并进行综合治理,使葡萄花难压层压裂成功率从A区块的77.1%提高到88.3%,为后续相邻区块方案优化提供借鉴。in view of the shortage of identifying difficult reservoir pressure according to reservoir thickness in Daqing peripheral oilfield, 10 parameters, such as reservoir thickness and lithological characteristics, which may affect the level of fracture pressure in the grape flower formation in block A were analyzed by single factor, normalization and correlation degree quantization to identify the main parameters affecting the fracture pressure of the reservoir. Then,through the comprehensive evaluation and analysis of the main parameters, A method for identifying the difficult pressing layer of grape blossom was established, which was used to identify and comprehensively treat the difficult pressing layer of grape blossom in the adjacent block B, so that the success rate of fracturing of the difficult pressing layer of grape blossom increased from 77.1% to 88.3% in block A,providing reference for the subsequent optimization of adjacent block plan.
