以"油铀兼探"的找矿思路,带动松辽盆地中南部开展砂岩型铀矿调查选区及钻探验证工作.将异常强度250 API和450 API确定为划分潜在铀矿孔、潜在铀矿化孔和正常孔的关键技术指标,对中央拗陷区南部1572个钻孔进行异常筛查工作.排查发现潜在铀矿孔362个,潜在铀矿化孔223个.对191号钻孔和36号钻孔进行钻探验证,发现1个工业孔、1个异常孔.认为区内寻找砂岩型铀矿的有利地段为油田区反转构造形成的隆起区边部四方台组河流相砂体,并总结了中央拗陷区南部6种主要控矿因素.  相似文献

石油、天然气、煤炭和砂岩型铀矿在同一盆地共同富集成藏为多种能源矿产的协同勘探提供了有利条件。地震和测井方法在各个能源矿产的勘探开发中都得到了广泛的应用。多种能源矿产的协同勘探应该利用现有的丰富的油气煤勘探开发资料(地震资料和测井资料)寻找砂岩型铀矿。鄂尔多斯盆地周边西缘逆冲带、天环凹陷、伊盟隆起和晋西挠折带这些砂岩型铀矿的远景区,据资料统计钻探油气井已达300口以上,为砂岩型铀矿勘探积累了丰富的地震和测井资料。  相似文献   

利用陕北地区测井资料识别煤层技术分析及对策

针对陕北地区水资源匮乏,油煤重复勘查导致地下水污染,以及单矿种勘查投资高的现状,开展油煤协同勘查可以节约水资源,减少投资成本,加快勘查进度。测井是协同勘查中重要的技术手段,采用油田测井和煤田测井资料对比的方法,分析油田测井资料在识别煤层方面存在的问题,认为在陕北地区可利用"高电阻、高声波时差、低自然伽马"的测井特征来识别煤层,并根据需要可增加高精度测井系列。  相似文献   

Progress in Study of Potash Resources of Oil (Gas) Field Brine in China

With a population of 1.3 billion, China is a large agricultural country. However, China is short of potash resources as the external dependence is more than 50% for many years. With the limited possibility for increasing potash reserves from surface salt lakes, and the challenge of finding potash deposit from marine strata has not been yet overcome, the oil (gas) field brine resources has become the preferred source for the urgent needs of potash. In recent years, a lot of exploration and research work on the oil (gas) field brine has been done under the guide of “oil and potash co-exploration” policy and delightful achievements have been obtained. The research achievements at Qaidam Basin, Sichuan Basin, Jianghan Basin and Tarim Basin were summarized in the present paper. All of the above basins are the most important areas with great prospects of oil (gas) field brine. This paper mainly focused on three aspects, the brine characteristics, the brine geochemistry and resource assessment. After the summary, the characteristics of oil (gas) field brine and the progress in study of that were gotten in different basins. It was suggested that the research work of (gas) field brine at Qaidam Basin should be emphasized. It was concluded that the evaluation work of oil (gas) field brine resources is insufficient at the four basins, and it is urgent to establish oil (gas) field brine resources evaluation criteria and methods.  相似文献
