摘要
针对准噶尔盆地二叠系致密砂岩油藏测井响应特征复杂多变,水淹层难以识别等难题,运用测井原理和方法建立水淹层的测井解释模型,提取含油饱和度、地层流动指数等水淹特征参数,并建立一套致密砂岩裂缝性油藏水淹层定量表征技术,能准确识别水淹层的测井响应特征。现场应用结果表明:该技术在实际油井应用中效果较好,方案实施后油井含水率由98%急剧下降至40%,日产油由0.5 t/d增至5.2 t/d,产能提高了近10倍,开发效果明显。研究成果为准噶尔盆地水淹层有效识别以及定量提供了技术支撑,为同类油藏水淹层识别及有效开发提供了参考。
In view of the complex and variable logging response characteristics of the Permian tight sandstone reservoirs in Junggar Basin,difficulty in identifying the water-flooded zones,and other challenges,a logging interpretation model was established for the parameters of the water-flooded zones according to the logging principles and methods,so as to obtain the characteristic parameters of water-flooded zone such as oil saturation and flow zone indicator.A set of quantitative characterization technologies for water-flooded zones in fractured tight sandstone oil reservoirs were developed to accurately identify the logging response characteristics of water-flooded zones.The field application results showed that the technology worked well in actual oil wells.After the implementation of the scheme,the water cut of the oil well was decreased sharply from 98%to 40%,the daily oil production increased from 0.5 t/d to 5.2 t/d,and the productivity increased nearly 10 times,with obvious development effect.The research results enrich the effective identification and quantitative characterization of water-flooded zones in Junggar Basin,and also provide a reference for the identification and effective development of water-flooded zones in similar oil reservoirs.
