| 摘 要： | 黔北是贵州又一聚煤区,在煤系地区综合利用数字测井技术,测量3种以上有效的物性参数,即研究视电阻率、伽马-伽马、自然伽马等参数特征,对煤层、常见岩石、标志层、地质界线等作出定性解释,取异常曲线上的特征点,确定煤层的深度、厚度和结构,对钻探工程打薄或打丢的煤层(线)进行更正。除用于找煤外,还用于判定地质构造、计量放射性物质辐射剂量等多种应用。 |
| 关 键 词： | 数字测井 电阻率法 伽马-伽马法 自然伽马法 多参数测量 |

| Abstract: | North Guizhou is another coal concentrated area. By using digital log synthetically in this area, more than 3 kinds of effective physical parameter were measured, which include: the characteristic analysis of apparent resistivity, gamma-gamma, gamma-ray and other indexes, the qualitative explanation for the coal seam, familiar rock, key bed, geological boundary and the likes, pick-up of the characteristic point of abnormal curve, determination on the depth, thickness and structure of coal seam, corrections of the coal seams(lines) which were thinned or missed by drilling engineering. Besides the coal prospecting, the digital log was also used in judging the geological structure, calculating the radiation dose of radioactive substance and so on. |
| Keywords: | digital log resistivity method method of gamma-gamma gamma-ray method muti-parameter survey |
