大港油田盐水泥浆测井影响分析研究

Effects of Well Logging Data with Saline Mud on Dagang Oilfield

结合歧北斜坡地区的地层水性质,借鉴多口盐水泥浆井的测井资料及试油结果,利用泥浆侵入后非储集层比储集层更能准确反映地层信息,提出通过建立储集层深浅电阻率与邻近非储集层段电阻率的相关关系以及储集层径向电阻率差异的方法识别流体类型。在建立地区盐水泥浆井的油气识别图版标准的基础上,将电阻率比值法评价储层流体实现软件模块化,并挂接到Lead3.0软件上进行应用。

To combine the Qibei slope area of the formation water property, to learn from the mouth of saline mud well logging data and oil testing results and to use the mud inva- sion of non--reservoir more accurately to reflect the stratigraphic information than the res- ervoir layer, this paper describes types of fluid are identified through the establishment of reservoir depth resistivity and adjacent non--reservoir layers resistivity relationship and reservoir radial difference of the resistivity method. On the basis of oil and gas identifica- tion plate standard of the brine mud in wells, the reservoir fluid evaluation of the resistivity ratio method is realized into software modularity, and applied to lead 3.0 software.
