摘要
油田进入特高含水开发阶段,油层严重水淹,剩余油分布零散,给油田增油上产带来一定困难,搞清剩余油分布规律、产层水淹状况势在必行。中子寿命测井是近几年发展起来的一项开发测井技术,随着测井工艺的不断完善,相应岩心实验研究的展开,以及配套处理解释软件的开发,中子寿命测井技术得到迅速发展,以其快速直观的特点在找水、找串、堵漏、确定剩余油饱和度、判定水淹层方面都有较好的应用效果。
When oilfield development is in extra high water stage,the reservoir is serious flooded,the remaining oil is scattered distribution. It is difficult for oilfield to Increase production. Therefore, finding out the remaining oil distribution law and the producing layer flooded situation is imperative. Neutron lifetime logging is a development well logging technology developed in recent years, With the constant improvement of the well logging technology, The commencement of the study of the corresponding core experiments and the development of processing and interpretation software. Neutron lifetime logging technology is developing rapidly, its fast and intuitive to find water, find the string, plugging, to determine the residual oil saturation and determining the effect of water flooded layer has a good application.
