摘要： 在水平井钻井过程中，向钻井液混入油类或有机添加剂，往往会对气测显示造成干扰，影响油气层的发现和评价。传统的解决方法一般根据经验扣除部分气测值，扣除部分作为钻井液混油响应气测值，该方法无法准确测定地层油气显示值。根据来自地层的气测值和来自混油的气测值及各个组分的相对含量，通过计算，可实现钻井液混油响应气测值的较准确剔除，剔除后的气测值更加客观地反映地层含油气信息。该方法在胜利、中原、川东北、新疆等油田进行了现场应用，效果良好。该方法不增加成本，计算简单，可在所有混油钻井液气测录井中推广使用。

Abstract: During horizontal well drilling process, people often mix oil or organic additives into drilling fluid, which may have interference on gas measured indication and impact on the discovery and evaluation of oil and gas shows. The traditional solution is deducting part of the gas measured values based on experience, and regarding the deducting part as the gas measured values in response to oil?emulsion drilling fluid, which does not realize the proper measurement or quantitative elimination of strata oil?gas indication value. The relative content of each component is different between gas measured values from the strata and the oil?emulsion drilling fluid, by which such a proper quantitative elimination that may objectively reflect in?situ hydrocarbon?bearing information can be made through calculations. This approach has been successfully applied to Shengli oilfield, Zhongyuan oilfield, northeastern Sichuan and Xinjiang, etc, without increasing costs and complex calculations, thus can be widespread for use in gas logging with mixed oil?emulsion drilling fluids
