This paper correlates the source rocks with biology marks in natural gas formation asphalt by adopting indirect correlation method , recognizing that deep natural gas mainly comes from jurassic and denglouku formations 本文采用间接对比法，将源岩与天然气储层沥青中的生物标记物进行对比，认为深层天然气主要来自侏罗系和登娄库组地层。
Study on petrology , geochemistry and isotope chronology shows that the metallogenesis is closely related to granite - porphyry , which belongs to the early ordovician adakite formed in volcanic arc 花岗斑岩与成矿作用关系密切，从岩石学、岩石化学、年龄学等方面对花岗斑岩进行了研究，认为花岗斑岩属于志留世早期形成于火山弧环境的埃达克岩。
In addition , in view of the high gold contents in the lamprophyres , and the significance of yanshanian for gold mineralization in shandong , the relation between lamprophyres and gold deposit is also discussed in this paper 同时，考虑到鲁东地区煌斑岩中金含量普遍较高，且燕山期又是山东金矿的主成矿期，论文中对煌斑岩与金成矿之间的关系也作了一定的研究。
The distribution of non - structural gas reservoir is constrained by hydrocarbon generating depression and the distribution of high efficient reservoir , the non - structural gas reservoir is often located in a coincident position of the high efficient reservoir and in the crossover of uplift with depression 非构造气藏分布受生烃坳陷和高效储集层分布制约，常位于气源岩与高效储集层的叠合部位、隆起与坳陷的转换部位。
The lacustrine carbonate rocks in the wudaoliang group consist of boundstone ( stromatolite ) , micritic limestone , grainstone and micritic dolostone which were laid down in the shallow - water to bathyal , high - salinity and enclosed to semi - enclosed lake systems 五道梁群湖相碳酸盐岩分为生物粘结灰岩（叠层石） 、泥晶灰岩、颗粒灰岩与泥晶白云岩四大类，反映出沉积环境为一个具有浅水半深水、高盐度、半封闭封闭特点的综合湖泊系统。
It is considered that the sequence evolution in the palaeozoic went through the following three stages , the filling of evaporate platform , the filling of carbonate and detrital rock mixed deposits in epiric sea , and the filling of detrital deposits of lake - deltas in paralic inland sag 认为研宄区古生界层序演化经历了以下三个阶段：蒸发台地充填阶段、陆表海碳酸盐岩与碎屑岩混合沉积阶段，以及近岸内陆坳陷的湖泊三角洲碎屑岩沉积阶段。
We have carried out th / u dating on intercalated calcite samples . the results show that the capping flowstone layer is of an age of 94 ka , and the second one 220 ka . the fossil - bearing deposits which are bracketed by the two flowstone layers should be of an age between 94 and 220 ka 新生碳酸盐岩与骨化石的铀系测年结果表明：该地点覆盖含人牙化石堆积的表层钙板在约94ka以前开始形成，堆积叠压的钙板年代为约220ka ，人牙化石的年代应介于两者之间。
According to actual situation of production wells , external boundary conditions and coupled inner boundary conditions between welibore and adjacent rocks , welibore and production zones , adjacent rocks and production zones are constructed , and an alternate direction implicit finite difference algorithm ( adi ) is used to solve temperature models 根据生产井的实际情况，构建起外边界条件以及井筒与围岩、井筒与产层、围岩与产层之间的耦合内边界条件，采用交替方向半隐式有限差分方法( adi方法)求解所建立的井下温度场模型。
There are 3 types of reservoir for the continuing subsidence type basin , there are diapir reservoir , fault reservior , drape reservoir , and the source rock is apart from the reservoir , they are contact by fault ; and there are anticline reservoir , fault reservoir , incline reserve ir , mudstone reservoir under the denudation area , and the source rock is contact with the reservoir 以沉降为主要趋势的盆地的油气藏有底辟构造油气藏、断层油气藏、披覆构造油气藏，其烃源岩与油藏在空间上是分离的，并通过断层相连；剥蚀区以下的油气藏有背斜油气藏或断层油气藏、向斜油气藏及泥质岩油气藏，其烃源岩和油气藏可有密切的接触关系。
And then according to every process of tunnel construction , simulated analysis is carried out . by combining with monitoring and instrumentation of surround rock periphery displacement and the face of land to sink , surround rock with spray laminating force , surround rock body internal displacement , anchor rod axle force and protect and lining build strength , we have carried out scientific analysis and synthesis judgement of the stability of tunnel wall rock and the security of timbering structure 然后，根据隧道施工的各个工序进行模拟分析，并结合对围岩周边位移、地表下沉、围岩与喷层压力、围岩体内部位移、锚杆轴力、支护及衬砌强度进行的量测与监控，对量测结果作出了科学分析，从而对隧道围岩的稳定性和支护结构的安全性做出了综合评判。
