摘　　要：随着塔北地区吉拉克油田勘探开发工作的不断深入,对低电阻油层的认识与评价已成为该区油气储量与产量增长的重要工作。正确识别该区低电阻油气层,一直是测井解释的一大难题,也是影响测井解释成功率的主要原因之一。本文在分析吉拉克油田三叠系TII低电阻油层成因的基础上,利用地层测试技术、孔隙度-电阻率差值比交会技术及视冲洗带电阻率重叠技术,提出了该区油、水界面及流体的识别方法。现场资料的应用取得了较好的效果,为该区低电阻油气层的评价提供了可靠依据。As the deepening of exploration and development in the Jilake oilfield,north Tarim area,identification and evaluation of low-resistivity reservoirs have become important to increasing oil and gas reserves and production.Proper identification of low-resistivity reservoirs has been a major problem in logging interpretation.Based on analysis of the genesis of the TII low-resistivity reservoirs in the Jilake oilfield,the method of identifying oil and water zones for this area has been established by using formation testing technique,porosity-resistivity difference ratio crossplot technique and apparent flushed zone resistivity method.The application to field data has achieved good result and provided reliable basis for identification of low-resistivity reservoirs in this area.
