摘要
针对上古生界山西组、太原组煤层较脆、钻时较快的特点,为保证现场煤层卡取心层位和准确划分煤层厚度,结合综合录井仪的钻时录井间距可以根据地质需要人为缩小的功能,使用“微间距录井法”对煤层进行精细卡层。结合现场实例对上述方法的特点及应用效果进行了介绍,以数据对比的方式阐述了该方法的优越性。该方法在现场使用取得了较好的效果,值得在现场推广应用。
In view of features that coal seams in Groups Shansi and Taiyuan from Upper Palaeozoic were brittle and penetration rate was fast, in order to ensure field sticking coring horizons and divide coal seams′thickness correctly, and combining the function that drilling time interval for comprehensive logging unit could be artificially reduced according to the needs of geology, the coal seams could be fine sticked with the micro-interval mud logging method. With on-site samples, the paper made an introduction of the above method characteristics and applied results, and set forth its superiorities in the mode of data correlation. Micro-interval mud logging method had achieved good results in on-site application and it was well worth for popularizing and applying at wellsite.
