摘要:
2011年以来,在东营凹陷和沾化凹陷部署了一系列页岩油专探井,但页岩油产量并未达到预期效果,表明前期对东营凹陷和沾化凹陷陆相页岩油的富集规律认识不清。以东营凹陷和沾化凹陷页岩油出油井为对象,综合数理统计、系统井解剖和实验模拟方法,明确了页岩油的富集产出主要受岩相、裂缝、页岩油可动性和地层压力等因素控制。在明确主控因素的前提下,对有利于页岩油富集各项因素的边界条件进行分析,建立了适用于陆相湖盆页岩油评价的基于岩相、(微)裂缝、页岩油可动性和地层压力的单因素评价、多因素叠合的页岩油甜点综合评价方法,有效提高了页岩油的预测精度,预测了页岩油甜点的有利区。研究表明,东营凹陷和沾化凹陷具有较好的页岩油勘探潜力。
Abstract:
A series of exploration wells targeted at shale oil have been deployed in Dongying sag and Zhanhua sag of Shengli oilfield since 2011. But the shale oil production rate can’t achieve the expected results, which indicates the understanding about the continental shale oil accumulation in Dongying and Zhanhua sags are not clear. Taking the shale oil wells in the 2 sags and combining mathematical statistics, well analysis and experimental simulation, the paper considers that the accumulation and production of the shale oil in the areas are mainly controlled by four factors such as lithofacies, fracture, mobility of shale oil and formation pressure. The boundary conditions of these factors favorable for shale oil enrichment are analyzed and a comprehensive evaluation method suitable for lacustrine shale oil evaluation is established based on single factor evaluation of lithofacies, fracture, mobility and formation pressure and multi?factor combined evaluation of shale oil sweet spot, which effectively improves the prediction accuracy for shale oil and forecasts the favorable area of sweet spot. The study shows good potential for shale oil exploration in Dongying sag and Zhanhua sag
