| 摘 要： | 混油泥浆钻进或卡钻时泡油解卡,必然对岩石样品造成不同程度的污染,对地化录井影响也在所难免。通过模拟实验方法分析混油泥浆对岩心、岩屑和井壁取心的污染程度及其对地化录井的影响,证明了混油泥浆对岩心和岩屑样品分析结果的影响可以忽略不计,对壁心样品分析结果影响很大,不能用来进行储层评价。两口井现场录井实例说明,地化录井具有较强的抗污染能力和识别真假油气显示的能力。 |
| 关 键 词： | 混油泥浆 地化录井 模拟实验 污染 油气显示 |

| Abstract: | During the process of drilling or drill pipe sticking, the influence of oil emulsion drilling fluid on geochemical logging and its varying degrees of pollution on rock sam- ples can not be avoided.Through simulation experiment, the influence of oil emulsion drilling fluid on geochemical logging,and its pollution degree on core,cuttings and sidewall coring are carefully analyzed.The results indicate that its influence on core and cutting samples can be neg- lected.However,reservoir evaluation can not be carried out due to its bad influence on sidewall coring samples. Meanwhile,geochemical logging is found to be capable of anti-pollution and identify hydrocarbon show with on- site logging practice of 2 wells. |
| Keywords: | oil emulsion drilling fluid geochemical logging simulation experiment pollution hydrocarbon show |
