摘要
针对S油田高台子油层三次加密井解释厚度少划的问题，通过分析原因主要是由于流体性质和钻井泥浆体系的变化，使储油层在测井曲线上的反映发生变化，因此，利用原来的电性标准已不能准确地划分储层厚度。应用“岩心刻度测井”技术，优选出能够反映该区岩性、物性、含油性特征的测井参数，经过偏差校正、采用多参数判别方法，结合岩心描述和物性分析等资料，编制了电性图版，根据含钙层的特点，建立了含钙层判别图版，并形成了一套新的高台子油层厚度解释方法。利用5口取心井进行验证，解释精度有了很大的提高，较好地解决了厚度少划问题，为三次加密井的各类厚度解释提供了可靠的依据。
The problem of inadequate thickness interpretation in the third infilling wells of Gaotaizi Oil Formation of S Oilfield results mainly from the changes of both liquid properties and the system of drilling mud based on the analyses, which made the reflection changes of oil layers in the logging curve, so the reservoir thickness cannot be correctly classified according to the original criteria of electrical property. In order to solve the problem, the tech- nique of ＂ core calibrated log＂ is used to optimally select the logging parameters responding the lithology, physical properties and oil-bearing characteristics in the region, and by error correction, multi-parameter identifying method and integrating the data of core description and physical property analysis, the chart board of electrical properties is complied and then a set of new thickness interpreting methods for Gaotaizi oil reservoirs is established. By the proof of 5 coring wells, the interpreted precision has increased a great deal, so the above problem has been favoritely resolved, thus the reliable evidences are provided for all kinds of the thickness interpretations in the third infilling wells.
