密闭取心检查井岩心水淹判断方法研究

JUDGING WATERED-OUT METHOD OF CORES FROM SEALING CORE DRILLING IN-SPECTION WELL

本文通过对油基泥浆取心井和密闭取心检查井岩样资料进行综合分析研究，建立了喇、萨、杏油田萨、葡、高油层全渗透率段的原始含水饱和度图版和油层水淹判断图版，为低渗透薄油层和在外储层水淹状况的判断提供了准确、可靠的方法。

Based on the comprehensive analysis and study of cores from oil-based mud cor-ing well and sealing core drilling inspection well,original water saturation chart and wa-tered-out judgement chart of whole permeability sections in Sa.Pu.Gao oil reservoirs of La.Sa.Xing oil fields are set up.which provide provide accurate and reliable method for judging the watered-out condition of low permeable thin reservoirs and ultra low permeable reservoirs.
