Application of gas logging in Well Heifudi-1

摘要:

黑富地1井作为一口小口径油气地质调查井，文章以该井施工为背景，简要介绍气测录井施工的原理和操作步骤，对气测录井施工过程遇到的问题和解决办法进行阐述，指出本井气测异常的评价原则和按照该原则对黑富地1井钻遇气层的判定情况，并参照气测录井结果和施工过程中的经验，分析在施工过程中影响气测录井数据准确性和录井曲线连续性的主要因素，探索小口径油气地质调查井气测录井操作规范，说明由于小口径钻井特点对油气储量评价带来的影响。

Abstract:

Well Heifudi-1 is a small diameter geological survey well for oil and gas, and in the context of drilling of the well, the basic principle and operation steps of the gas logging is introduced in this paper. The problems encountered and relevant solutions in gas logging are described. The evaluation principle for abnormality detected by gas logging in the well is explained and used for evaluation of gas formation encountered in the well. With reference to the results and experiences of gas logging, this paper analyzes the influence of major factors on gas logging data accuracy and logging curve continuity, explores the operating procedure of gas logging in small diameter geological survey wells for oil and gas, and describes the effect of small diameter drilling characteristics on the evaluation of oil and gas reserves.
