摘要
针对SYS区块复杂钻井工艺与地质条件下,现场岩屑难以反映地层真实岩性的实际情况。探讨提高岩屑识别及代表性的方法,一是运用常规岩屑识别方法,采用“大段摊开,宏观细找;远观颜色,近看岩性”等原则,识别真假岩屑;二是岩屑体积追踪法解决岩屑代表性差的问题从而提高岩屑识别;三是运用碳酸盐岩分析仪;四是综合运用常规录井参数与钻井参数辅助识别岩性。
In view of the complex drilling technology and geologic condition in SYS block,field cuttings can’t characterize the actual formation lithology.This paper puts forward methods to improve cuttings identification and representativeness.First,using conventional method to indentify cuttings on the basis of“spreading large segments and finding out problems carefully within the intervals,observing from color at a distance and looking closely form lithology”to distinguish false cuttings.Secondly,using debris volume tracing method to solve the problem of poor representativeness of cuttings thus to improve cuttings recognition.Thirdly,using carbonate analyzer.Fourth,integrating conventional logging parameters and drilling parameters for lithology identification.
