在前人工作基础上，重点以青海煤炭地质一0五勘探队在青海木里三露天实施的系列天然气水合物钻井资料为基础，根据已发现天然气水合物产出层位、岩性、深度、气体异常、厚度变化、主控断层等信息，同时通过对地质异常、三维地震、测井化探、微生物多种方法技术的成果对比和分析，在平面上确定出研究区天然气水合物分布区块，进一步运用体积法估算了青海木里聚乎更煤矿区三露天地区天然气水合物资源量，并对其经济可采性进行了初步评价。结果显示，三露天地区天然气水合物烃类气体控制的地质储量和推测的地质储量分别为213.85万 m3和452.60万 m3；结合对三露天调查区天然气水合物的地质认识、资源量、开采技术条件等因素的综合分析，认为调查区天然气水合物赋存情况复杂、资源量偏低、开采技术不成熟，目前暂不具备经济开采价值。

On the basis of predecessors'work and a series of drilling data obtained from the gas-hydrate drill-holes carried out by Qinghai No.105 Coal Geological Exploration Team in Sanlutian of Muli,Qinghai together with the analysis of 3D-seismic,logging,geochemical and microbial data,the plane distribution of gas hydrates in this area was delineated with the use of hydrate-bearing intervals'lithology,depth,thickness,gas-content anomaly and main faults.The gas-hydrate reserve in the study area was further estimated using the volume method,and the results show that the gas-hydrate reserve in prospects is about 2.138,5 million cubic meters and the inferred gas-hydrate reserve is about 4.526 million cubic meters.After the comprehensive analysis of the geological information,the gas-hydrate reserve in the study area and the production technics of gas hydrates, it comes to the conclusion that the gas-hydrate reservoir in Sanlutian is of no industrial exploitation value be-cause of the complex occurrence situation,low reserve and immature mining technology at present.
