【摘要】：三维定量荧光技术能够克服大斜度钻井时落实油气显示的难题。本文为此通过研究制定了技术规范,包括样品的挑选和处理、分析取样密度、合理的稀释倍数。通过大工作量的统计后,研究制定了显示层的识别方法,高荧光背景下的显示识别方法,并建立了相应的解释图版。元素录井技术能够克服大斜度钻井时岩屑代表性差导致的剖面符合率低的问题。本文为此通过研究制定仪器标定和样品分析技术规范,分析各种影响因素。通过对冀东油田常见岩石的元素分析,建立了元素数据库,并由此研究出岩性解释的方法,尤其是针对特殊的碳酸盐岩根据元素含量变化及元素曲线形态分析判断原始沉积环境,获得了较大的突破。应用三维定量荧光技术后,33口井的油气显示发现率为100%,油气显示解释符合率由70%提高至80.4%。应用元素录井技术后,潜山界面卡取准确率100%,剖面符合率达91.3%,资料解释符合率明显提高。本文研究重点是解决大斜度井录井过程中的油气显示识别及岩性识别问题。因此,以三维定量荧光录井及元素录井技术展开研究,全面探讨技术原理,总结技术方法,应用于现场及推广等。
[Abstract]:Three-dimensional quantitative fluorescence technology can overcome the problem of implementing oil and gas display in large slope drilling. In this paper, a technical specification was formulated, including the selection and treatment of samples, the analysis of sampling density and reasonable dilution multiple. After a large amount of work statistics, the identification method of the display layer was developed, and the display under high fluorescence background was shown. The method of identification and the corresponding interpretation chart have been set up. Element logging technology can overcome the problem of low profile coincidence rate caused by bad cuttings in large slope drilling. In this paper, the technical specifications of instrument calibration and sample analysis are formulated and various influence factors are analyzed. The method of lithologic interpretation is set up and the method of lithologic interpretation is studied, especially for the special carbonate rocks to judge the original sedimentary environment according to the element content change and the element curve form analysis. After the application of the three-dimensional quantitative fluorescence technology, the oil and gas display discovery rate of 33 wells is 100%, and the oil and gas display interpretation conforms to it. After increasing the rate from 70% to 80.4%. application element logging technology, the accuracy rate of the Qianshan interface card is 100%, the section coincidence rate is 91.3%, the coincidence rate of the data interpretation is obviously improved. The key point of this paper is to solve the identification of oil and gas display and the lithology identification in the well logging process of large inclined wells. Study, discuss the principle of technology, summarize the technical methods, apply to the scene and promotion.
