常规测井技术作为采油业常用测井手段,如果深入地下高含水期作业,不仅不能提供出高精准度参数,且所提供的纵向分辨率也会存有很大差异。因此采油行业为了提高采油效率,引进了一大批油田开发高新技术。薄层电阻率(TBRt)测井技术作为采油业为提高采油效率而引进的先进技术之一,能够分析储层渗透性、能够推动岩心实验研究的开展、能够评价非均质砂层、能够指示薄互层可动油气、能够计算砂层净砂体厚度、能够划分薄互层以及能够评价分析灰质夹层等,作用远超于常规测井技术,带给了石油开发测井更大的收益。本文主要说明了薄层电阻率测井技术的组成、工作原理以及具体应用。
Conventional logging technology, as a commonly used logging tool in the oil industry, not only can not provide high-precision parameters, but also provides a great difference in vertical resolution. Therefore, the oil recovery industry in order to improve oil production efficiency, the introduction of a large number of oilfield development of high technology. As one of the advanced technologies introduced by the oil recovery industry to improve oil production efficiency, the thin-layer resistivity (TBRt) logging technology can analyze the permeability of reservoirs and can promote the experimental study of cores. It can evaluate heterogeneous sand layers and can indicate Thin interbedded movable hydrocarbons, the ability to calculate the thickness of sand bodies in the sand, the ability to divide thin interbeds, and the ability to evaluate and analyze gray matter intercalations, have far exceeded conventional logging techniques and have provided greater benefits to oil development logging. This paper mainly describes the composition, working principle and application of the thin-layer resistivity logging technology.
