For the influen- cing factors of drilling time,drilling fluid inlet flow rate when the hydrocarbon reservoirs are drilled into,the total hydrocarbon detecting values will be different for the same reservoir conditions,and even the difference is great.
气测录井随钻检测的全烃值是发现和评价油气层的重要参数,但由于钻开油气层时受钻时、入口钻井液流量等因素的影响,相同储集层条件下其全烃检测值有所不同,甚至相差较大。
