In the end , the thesis supplies the parameter of magnetic & susceptibility anomaly forecasting oil and gas reservoir and pointed out the association with the parameter and the compartmentalized oil & gas perspective region may improve the precision rate greatly in magnetic exploration searching oil and gas reservoir directly 油井资料验证了磁性资料探测油气藏结论,验证结果表明了资料的有效性和划分的合理性。由此,本文给出了磁异常? ?磁化率异常联合预测油气藏量化因子,指出此因子配合油气远景区图示可以大大提高磁性指标直接探测油气藏的准确率。
By summarizing and analyzing the geological setting , uranium source , paleoclimate , hydrology , lithologic - lithofacies conditions in the region , it is indicated that the quantou formation in fanjiatun - jiutai area and the qingshankou formation in yangdachenzi area are potential metallogenic prospective areas for in - situ leachable sandstone type uranium deposit in the region , which develop braided channel or delta marginal sandstones , and possess favorable forming conditions of interlayer oxidation zone , and constituting supply - passage - discharge system of abundant uranium source 综合研究区域成矿地质背景、铀源、古气候、水文地质、岩性岩相条件,认为范家屯九台一带的泉头组及杨大城子一带的青山口组发育辫状河或三角洲前缘砂体,构成了铀源供应充足的补径排系统,具有有利的层间氧化带形成条件,是本区地浸砂岩型铀矿的有利成矿远景区带。
From geological view points , traditional economic or exploration geologists should take it into consideration of the environmental problems from different phases of mineral exploration ( exploration planning , regional exploration , prospect evaluation and prospect characterization ) and use the data for the purpose of exploring mineral resources to solve environmental problems for the mining planning and mining 本文从矿产资源勘查角度,讨论在矿产资源勘查的不同阶段(区域矿产普查、远景区勘查到矿床勘探即详查) ,传统资源学家所必须考虑的环境问题及地质勘探过程中所获资料在矿床(山)环境评价中的作用。
Beginning with the features of regional geophysical and geochemical fields in bazinao - zhanggongshan area , combinied with the available data of regional basic geology , this paper has put forward five i or ii grade potential au , sn enrichment zones on the basis of geophysical and geochemical metallogenic conditions of regional strata , magmatic rocks and structures 摘要从八字脑彰公山地区的区域地球物理场、区域地球化学场特徵分析入手,结合区内已有区域基础地质资料,研究了区域地层、岩浆岩、构造的地球物理地球化学成矿条件,提出了5个金、锡矿i 、级资源富集远景区。
And mainly applies gis to appraise gold resources of south ningxia , deeply synthetically analyzes gold metallogenic geological setting , mineralizing characters , ore - control factors and metallogenic law , appraises and predicts gold ore - prospecting prospective domain , brings forward ore - search directions , and appraises potential gold resources 主要应用gis技术进行宁夏南部地区金矿资源评价,深入综合分析了金矿成矿地质背景、矿化特征、控矿因素及成矿规律,评价预测了该区金矿找矿远景区,提出了找矿方向,并对金矿资源潜力进行了评估。
Selecting youxi - dehua - yongtai , zhenghe , taining and shanghang prospecting metallogenic provinces ( total area 2516 km2 ) , which have good gold - finding prospective and relatively rich data , and using the method of characteristic analysis and information extraction to seek gold prospecting target , the author builds the gold deposit forecast models of metamorphic rock category and the volcanic rock category , determines 86 good gold - finding units in fujian and assesses the gold resource extent of the order v prospecting metallogenic provinces in shanghang , taining , zhenghe , and youxi - dehua - yongtai and jianyan , . which provides important reference basis for seeking gold deposits in next survey 选择尤溪?德化?永泰、政和、泰宁和上杭四处成矿远景较佳、资料水平较高的成矿远景区(总面积2516km ~ 2 ) ,利用特征分析和信息量法进行找矿靶区优选,建立了变质岩型金矿和火山岩型金矿的预测模型,优选出有利成矿单元86处。对上杭、泰宁、政和、德化?尤溪?永泰和建阳级成矿远景区的金资源量进行了估算,为省内下一步金矿的找矿工作提供了重要的参考依据。
The thesis was written under the direction of dynamic theory of forming reservoir , follows the rules of comprehensive information , judgment , interpretation and assessment and even makes full use of outcrop geology , data from drilling and logging , data from laboratory analysis and achievements in geophysical exploration . considering the basic factors of forming reservoir in the south of ordos basin as the starting point , the thesis defines that yanchang group of triassic goes into the start of generating oil in the late period of mid - jurassic and that the largest oil generation peaks in the middle period of early cretaceous , after the analogue - history of hydrocarbon generation . meanwhile it also establishes the relationship between the evolution of oil and gas and the formation of traps , the time of oil exploration 本文以成藏动力学理论为指导,本着综合信息、综合判断、综合解释、综合评价的原则,充分利用露头地质,钻测井资料,实验分析资料及物化探成果,以鄂尔多斯盆地南部的基本成藏要素为出发点,通过生烃史模拟,确定了三叠系延长组在中侏罗晚期( 150ma )进入生油门限,于早白垩世中期达到最大生油高峰期;同时并确立了油气演化与圈闭形成、捕油时间的关系;通过流体势的全区计算,提出了该区油势具有明显的“双层”结构特征,并建立了以静水压力为主的重力流系统和以差异压实作用为主的压实流系统的流体动力分布模型;通过成藏动力学系统的划分及事件分析,探讨了该地区油气聚集规律,最终指出了有利的含油气远景区。
In this thesis a deeply arrangement of exploration and new view of search for minerals has been suggested , beneficial metallogenic zones for types of main copper deposits pointed out and prospective prognosis area divided , and the providing reserves for bases of the copper mine productions and main ways going on development for old mines has also been discussed 提出了进一步找矿工作部署与矿产勘查研究的新思路;指出了主要铜成矿类型的成矿有利区带,划分了成矿远景区;从资源勘查开发角度,探讨了铜矿生产基地后续资源保障与老矿山解困的主要途径。
