摘要/Abstract

摘要：

开发不受沼泽微生物影响的地球化学勘查技术是提高中纬度冻土区天然气水合物探井预测成功率的重要课题之一。选择在祁连山聚乎更天然气水合物已知区进行土壤热释光勘查技术实验。实验区为高寒沼泽景观,面积150 km²,采样密度2点/km²,采样深度60 cm,采集土壤样品300件,应用热释光测量仪对土壤样品进行了热释光分析。实验结果表明,天然气水合物矿藏上方出现天然热释光高值异常,与烃类异常浓度范围一致,为顶部异常模式。结合地质和地球化学勘查成果对异常进行了综合解释,认为祁连山聚乎更地区天然气热释光异常与天然气水合物矿藏关系密切,源于深部水合物矿藏。研究对天然气水合物的进一步调查具有重要的参考价值。

Abstract:

The development of geochemical exploration technologies unaffected by marsh microorganisms is necessary to improve the prediction of wells and to explore natural gas hydrates in mid-latitude permafrost areas. The potential of thermoluminescence as a new tool for the investigation of gas hydrates in permafrost areas was studied in this paper. The study area, 150 km² in size, is located in the alpine-arctic swamp landscape of the Qilian Mountains. The sampling density and depth were 2 points/km² and 60 cm, respectively. In total, 300 soil samples were collected and the Thermoluminescent Dosimeter (TLD) was used in measurement of soil natural thermoluminescence. The results indicated that thermoluminescence anomalies were identified in the gas hydrate deposits. A comprehensive interpretation was conducted based on geological and geochemical survey results. The relationship between the hydrocarbon of gas hydrates anomalies and thermoluminescence anomalies was further explored. We proposed a geogas migration mechanism of soil thermoluminescence in the soil above the natural gas hydrate deposits. The soil thermoluminescence anomalies near the ground surface of the Muli Coalfield in the Qilian Mountains, derived from the deep hydrate deposits and fault structure, are not affected by marsh microorganisms; they are effective tools for natural gas hydrate exploration in permafrost areas.

Key words: thermoluminescence, natural gas hydrate, alpine swamp, permafrost, Qilian mountains
