    • An in-hole oil-drilling probe (10) is mountable in a drill string to measure hydrocarbon concentrations in drilling fluid flowing around the drill string. The probe consists of a drill collar (12) which is mountable in the drill string. A solvent, in which hydrocarbons are soluble, circulates within the drill collar (12) through a hydrocarbon detection chamber (28). A membrane (30) in the drill collar (12) has an outer surface (36) positioned to contact flowing drilling fluid and an inner surface (38) positioned to contact circulating solvent within the drill collar (12). The membrane (30) allows hydrocarbons to permeate from the drilling fluid into the solvent and into the hydrocarbon detection chamber (28) with the solvent. A radiant energy source (44) directs radiant ultra-violet energy into the hydrocarbon detection chamber (28). A sensor apparatus measures fluorescent energy radiating from the hydrocarbon detection chamber (28) to determine solvent hydrocarbon concentration. The sensor apparatus preferably comprises a pair of sensors (54, 56) which are responsive to two different energy wavelengths, respectively, to discriminate from hydrocarbons originating from sub-surface fluids and hydrocarbons (primarily diesel oil) orginating from drilling fluid.
    • 钻孔钻探探针(10)可安装在钻柱中以测量在钻柱周围流动的钻井液中的烃浓度。 探头由钻铤(12)组成,其可安装在钻柱中。 其中可溶解烃的溶剂在钻铤(12)内通过烃检测室(28)循环。 钻铤(12)中的膜(30)具有定位成接触流动的钻井流体的外表面(36)和定位成与钻铤(12)内的循环溶剂接触的内表面(38)。 膜(30)允许烃从钻井液渗透到溶剂中并与溶剂一起渗入烃检测室(28)。 辐射能源(44)将辐射的紫外线能量引导到烃检测室(28)中。 传感器装置测量从烃检测室(28)辐射的荧光能量以确定溶剂烃浓度。 传感器装置优选地包括分别响应于两个不同能量波长的一对传感器(54,56),以区分源自钻井液的亚表面流体和烃(主要是柴油)的烃。
