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。
Combined with the properties of formation water in the slopes of the northern part of the country, using the logging data and oil test results of multi-salt saline well, the non-reservoir information can reflect the formation information more accurately than the reservoir after mud invasion. The correlation between depth resistivity and the resistivity of adjacent non-reservoir segments and the difference in radial resistivity of the reservoir identify the fluid type. On the basis of establishing the standards of oil and gas identification plates in the salt mud wells in the region, the resistivity ratio method is used to evaluate the reservoir fluid to modularize the software and to be connected to Lead3.0 software for application.
