摘要
岩心核磁共振测井技术具有测量结果准确、对岩石结构无损害的优势,在油田勘探开发中应用越来越广泛。针对北黄海东部坳陷中、新生代有岩心核磁共振的资料进行解谱处理方法研究,确定了预处理、解谱和地层参数求取方法与流程,实现了岩心核磁共振资料解谱处理。根据最优解谱方法得到有效孔隙度、可动流体孔隙度、束缚水孔隙度和渗透率等地层参数。
NMR logging technology,due to its accurate measurement result and the advantage of detecting lithological texture without damage,is increasingly and extensively applied in oil exploration and development.In this paper,we focused on the core data spectral processing method of NMR taking the Eastern Depression of the North Yellow Sea as a case.Pretreatment,spectrum analysis and formation parameter method and process were discussed for the core data processing of NMR.Using the optimal solution spectrum method,we obtained the data of effective porosity,movable fluid porosity,bound water porosity and permeability of formation parameters.
