【摘要】 钻井液粘度对气测录井影响较大。对不同钻井液体系在不同粘度下气体检测的实验研究分析,得到了不同钻井液体系的气测全烃检测对比关系。通过不同体系粘度使用范围的优化,确定最佳粘度值,以天然气检测解释标准为例建立了不同钻井液体系的录井气体检测解释标准。实际应用表明,不同钻井液体系的气测录井资料的校正是必要的,也是可行的。更多还原

【Abstract】 Drilling fluid viscosity has greatly affected gas detection logging. The experimental analyses of gas detection of various viscosity under different drilling fluid systems are made. Comparative relation of gas detection total hydrocarbon monitoring of different systems is worked out according to the experimental results. By optimization of the viscosity application scope of the different systems, the optimum viscosity value is deter mined. Logging gas detection interpretation standards of different drilling fluid systems are established, taken an example of the gas dectection interpretation standards. In fact it is necessary and feasible that the gas detection logging material is calibrated under different drilling fluid systems.更多还原
