It is controlled by fractured zones cutting through vein zones. Host rocks are mainly cataclastite and breccia which are derived from felsic veins, meta-quartzose sandstone, meta-andesite, slate and siltstone, etc. Mineralization is present predominately in the form of fracture fillings and it has no close relation with chemical compositions of the wall rock. Wall rock alterations include sericitization, silicification, potassic feldspathization, biotitization, pyritization, hematitization and hydrous kaolinization. Uranium minerals comprise mainly pitchblende, uranium black, coffinite, with minor brannerite and zippeite. Uraniferous minerals are anatase, rutile, hematite, hydrous kaolinite and limonite, etc. Other metallic minerals are essentially molybdenite, pyrite, galena and chalcopyrite. The uranium ores exhibit veinlike, brecelated, massive and disseminated structures and pitchblende has colloform texture. Molybdenum reserves in the deposit are much more than uranium reserves. The uranium orebodies occur within or at the margin of the molybdenum orebodies. Laboratory and field studies show that this deposit may be considered as a molybdenum-uranium composite deposit of meso-and epithermal origin associated with intermediate acidic small intrusions. 矿床产于中元古代地层中。矿区内酸性脉岩发育,常密集成带,矿床受穿过脉岩带的构造破碎带控制。矿化岩石主要为构造碎裂岩和角砾岩,其原岩为长英质脉岩、变石英砂岩、变安山岩、板岩及粉砂岩等。矿化以裂隙充填为主,对围岩化学成分的选择性不大。围岩蚀变有:绢云母化、硅化、钾长石化、黑云母化、黄铁矿化、赤铁矿化及水合多水高岭石化等。铀矿物主要为沥青铀矿、铀黑、铀石,其次有钛铀矿、水铀矾,含铀矿物有锐钛矿、金红石、赤铁矿、水合多水高岭石和褐铁矿等;其它金属矿物主要有辉钼矿、黄铁矿、方铅矿和黄铜矿。矿石具脉状、角砾状、块状和浸染状构造,沥青铀矿具胶状结构。矿床中钼的储量远大于铀,铀矿体产于钼矿体之中或其边部。通过室内、外研究,可以认为本矿床为与中酸性小侵入体有关的中-低温热液成因的钼-铀型复合矿床。 Since 1982, we have taken IP research for oil exploration at more than 20 oil fields in different parts of China.

Since 1982, we have taken IP research for oil exploration at more than 20 oil fields in different parts of China. This paper takes the oil field in region K at north-west of China, as a main example, to examine the mechanism of the cause of the IP anomaly over oil reservoir in detail. According to the results of many different kinds of physical and chemical determinations and analysis, we have come to the conclusion that the main geological factor which causes the IP anomaly is the pyrite mineralization distributed in the shallow layers over the oil reservoir. We infer that the pyrite mineralization relates closely to the diffusion or escape of the hydrocarbon substance from the oil reservoir. Along the vertical direction, the variation of the substance in the overburden layers has been investigated theoretically and practically. Thereby, we provide a referable geologecal-geochemical-geophysical model which refers the vertical variation of the material and of the ρs, Ms property of the overburden layers. 根据1982年以来在华北、西南、西北、华东等地大小20余个油田上进行激电找油的研究工作,特别对西北K区等油田进行的异常成因机制的剖析工作:激电测井、井中取样分析鉴定、扫描电镜观察、物性测定、数字模拟及同位素分析等,以充分论据证实了引起激电异常的主要地质因素是油藏上方浅部地层中的次生黄铁矿化分布。论述了黄铁矿化与烃类扩迁的密切关系。并对西北K区等油藏上方地层的垂向物质变异的规律,结合实际资料,从理论上进行了分析和解释。最后提出了油藏上覆地层垂向变化的地质-地球化学-地球物理综合参考模型。 It is generally considered that the induced polarization (IP) anomaliesover oil and gas accumulation are due to pyritizatiou in association withmigration of hydrocarbon compound. However, the IP experiment inCentral Hebei and the geological and hydrogeological study in Renqiudistrict in particular allow us to think that the IP anomalies over oil and gasaccumulation are not related to pyritization only, but to many factors. TheIP anomalies over the Renqiu Oilfield are mainly produced by the filmpolarization effect...

TheIP anomalies over the Renqiu Oilfield are mainly produced by the filmpolarization effect of ion conductor affected by temperature, salinity ofground water and clay mineral content. 目前,国内外资料普遍认为油气藏上的激电异常主要是由于与类物质运移有关的黄铁矿化所引起的。本文通过对冀中地区激电找油试验工作资料,结合任丘地区地质、水文地质特征和油气生成、运移规律的分析,初步认为油气藏上的激电异常与多种因素有关,任丘油田上的激电异常主要为离子导体的薄膜极化在温度、地下水矿化度、粘土矿物含量等因素的影响下产生,其激电异常与受温度、地下水矿化度、粘土矿物含量影响的极化体电阻率有关。   << 更多相关文摘      相关查询 黄铁矿化菌落 黄铁矿化植物 已黄铁矿化
