摘　　要：依据黄沙坨油田油气井的实际生产动态资料,将油气井进行分类,认真识别和研究辨识其不同的裂缝发育类型和储层特征,不断校正岩心、测井、物探、应力场和有限元等静态资料的认识缺陷,排除泥浆污染油层等因素对储层研究解释的干扰;得出高产速淹井生产特征对应的高角度裂缝发育在构造的主体部位,中产缓淹型油气井的生产特征背后,对应网状裂缝～孔隙发育类型和构造"腰部"的分布范围,低产不淹或不窜型油气井对应微缝细孔等储集空间类型,主要分布在构造的边部;并利用物质平衡法等油藏工程研究软件,对裂缝储层参数进行量化,分析调整措施的政策界限,为类似油田的勘探和开发,进行了有益的尝试,提出的动态辨识裂缝和储层的新方法,在生产实践应用中,见到了较好的节能与挖潜效果。Based on the performance data of the actual production of oil and gas wells in Huangshatuo oilfield, the classification of oil and gas wells is undergone; various fracture growth types and reservoir characteristics are carefully identified and studied; cognition faults of these static data such as core, logging, geophysical exploration, stress field as well as finite element are continuously corrected ; the disturbance of the mud - contaminated oil reser- voir to the research and interpretation of reservoir is eliminated. It has been concluded that the high angle fracture corresponding to the fast watered - out high production characteristics grows in the structural principal position ; the production characteristics of oil and gas wells with the slow watered - out medium production show they belong to net fracture - pore types and distribute in the middle of the structure ; low production wells with non - flooded or non- channeling characteristics show they belong to micro -fracture and fine pore types and locate in the edge structure. Applying material balance method and other petroleum reservoir engineering software quantifies reservoir parameters and analyze the adjustment measure for different fracture reservoirs, which executed a useful attempt for exploration and development of the similar oilfield. The new methods proposed to differentiate fracture and reservoir dynamically got good energy - saving and potential effect in practical application of production.
