摘要:

土库曼斯坦阿姆河右岸为盐下中上侏罗统低能缓坡礁滩型碳酸盐岩储层,储层基质物性差,裂缝发育。单井产能与裂缝发育程度密切相关,准确评价裂缝发育程度是产能建设过程中极为重要的一环。通过对研究区不同倾角裂缝有效性进行分析,认为高角度裂缝的有效性较高,对生产起主导作用;根据岩心观察统计、成像测井裂缝解释及常规测井响应特征分析,认为裂缝发育程度与双侧向幅度差大小及总孔隙度与声波孔隙度之差呈线性正相关,但不同岩相裂缝发育程度的测井响应特征存在差异;通过开展从单变量到相控_单变量的常规测井裂缝评价研究,最终采用“相控”多元线性回归方法,实现了不同岩相裂缝密度定量解释,形成了相控_多变量裂缝发育程度定量解释方法。岩心资料、测试资料及井漏情况表明解释结果较为可靠,可应用于相似类型储层裂缝发育程度常规测井定量评价。

Abstract:

It is low-energy ramp reef-shoal carbonate reservoir of sub-salt Middle-Upper Jurassic in central Amu Darya right bank block,with poor matrix properties and well-developed fractures.Single well deliverability is closely related to the fracture intensity.Accurate evaluation of fracture intensity is very important for the deliverability construction.The fractures in this area are of different angles.And the high angle fractures are more effective.The features of imaging logs and conventional logs are studied.The relationships between high angle fracture intensity and single log are set up.The intensity is linearly and positively relevant to the ratio of deep and shallow lateral resistivity and the difference of density and acoustic porosity.But the fracture intensity is different in different microfacies.Therefore,based on the microfacies,the models for fractures of different microfacies are set up with multiple linear regression method.The models are proved reliable with coring data,test data and lost circulations.This method can be used for similar fractured carbonate reservoir.

Key words: Carbonate, Ramp reef-shoal reservoirs, Fracture intensity, Conventional logging, Quantitative interpretation
