Lithologies are mostly sand and carbonate rocks, caps are mud rock, shale and magmatite. Entrap types are anticline, fault block rebuilt by breaking and the screened entrap diapered rock mass. The composition is CO_2, N_2, CH_4, C_2H_6 and He etc. It is magma air source body and its geologic fashions are intrusion and buried volcanic conduit. The relations between gas reservoirs and gas source bodies have three types: magma intrusion-breaking-communicated gas reservoir, magma intrusion-contacted CO_2 reservoir and buried volcanic conduit-contacted gas reservoir. The CO_2 migration in magma intrusion is consisted of fusing and crystallizing phases;it in volcanic conduit is consisted of near-surface effusion and crystallizing phases.The buoyancy of CO_2 in water far more than migration resistance in breaking or chink, CO_2 is easy float upward, the floating can results in differentiation of different density gases and concentration of sealed gas. The gas in sand reservoir firstly migrate into the higher porosity and coefficient of permeability sand, and along with the pressure going up it migrate into the lower. In magma intrusion-breaking-reservoir migration, CO_2 firstly migrate into watered breaking, began gravity differentiation and concentrate, the gas pressure time and again go up, CO_2 migrate into reservoir and concentrate under expansibility as the pressure reach upward a given extend. The CO_2 in reservoir experience four breaking modes: chemistry deposition, dissolution, diffusion and mechanic breaking, the pressure balance can be broken by faulting and the CO_2 will further migrate and form new reservoir.

济阳坳陷已发现的八里泊、阳25、平方王、平南、高青、花17 CO_2气藏主要储集层位有奥陶系、中生界、沙四段、沙三段、沙一段、馆陶组和明化镇组，储集层岩性以砂岩和碳酸盐岩为主，盖层以泥质岩、页岩和岩浆岩为主。；圈闭类型主要为受断裂改造的背斜、断块及刺穿岩体遮挡圈闭。；气体成分主要有CO_2、N_2、CH_4、C_2H_6、He等。；主要气源体为岩浆气源体，气源体的主要地质形式为侵入体和埋藏的火山通道。；气藏和气源体的空间关系有岩浆侵入体一断裂一气藏沟通型、岩浆侵入体-CO_2气储集层接触型和埋藏火山通道-气储集层接触型三种类型。；岩浆侵入体CO_2气运移分为熔融运移阶段和结晶运移阶段，火山通道中CO_2气运移分成近地表喷发阶段和结晶运移阶段。；断裂中，CO_2在水中的浮力远大于运移阻力，CO_2气容易上浮，CO_2在断裂中的易浮性导致不同密度气体的分异和走向上封闭的断裂气体相对富集。；气体在砂岩储集层运移聚集具有选择性，会优先进入孔隙度和渗透率较高的砂岩，随着压力增加，才会进入孔隙度和渗透率较低的砂岩；在岩浆气源体-断裂-储集层空间输导格架下，CO_2气在膨胀力的驱动下，首先进入含水的断裂并重力分异而聚集，气体压力会不断增高，当压力增至一定程度，CO_2气会向高孔隙度、渗透率的储集层运移并聚集。；在岩浆气源体-储集层接触空间输导格架下，CO_2气受膨胀力的驱动直接向储集层运移并聚集。；成藏的CO_2气会经历化学沉淀、溶解、扩散和机械破坏四种破坏方式，会受断裂切割而打破压力平衡，沿断裂进一步运移和聚集成藏。

During well drilling, LWD monitoring device, comprehensive logging device, cutting logging, seismic interpretation, geologic models, and many other technical measurements had been used for real-time monitoring and comprehensive analysis. What had been done helped geosteering, and the putting forward of drilling track. The horizontal wells drilled in ultra thin single sand layer with the thickness of less than 2m, and the penetration rate for sandstone was higher.

在现场钻井过程中，采用LWD监控仪、综合录井仪、岩屑录井、地震解释、地质模型等多种技术手段相结合，实时监控，进行综合分析，为地质导向提供依据，并准确地指导了钻井轨迹运行，实现了在不到2m的超薄单砂层中穿行，达到了较高的砂岩钻遇率，并成功的穿越了小断层，实现了二次着陆。

Beginning with areal geologic background, the authors have discussed the features of quartz vein at Rujigou mining area Ningxia, such as lithology, contact correlation with wall rock, scales, space-time distribution, attitudes, assemblage, mineral inclusion, and have compared the quartz vein with the veins within other coalfields and coal measures.

笔者从地质背景入手，较详细的论述了汝箕沟矿区石英脉的岩性、与围岩的接触关系、规模、时空分布、产状、组合、矿物包裹体等发育特征，比较了该区石英脉与诸多煤田和煤系中脉岩的差异。

According the self-similarity of the sand flat conformation of delta sand and the vertical frequency of the mud thin bed and combine some basic geologic material and interrelated literatures, bring the theory of holographic geology first time, think that geological bodies are generated not only the physical grain, but also the sedimentary of the geological information, local geological body can contain much or all information of the whole geological body which it belong to.

根据三角洲砂体平面分布和泥质薄层垂向发育的规律性尤其是其自相似性，从空间和时间两个方面进行了总结，同时结合相关地质资料和国内外有关文献，初步提出了&地质全息&理论，认为地质体不仅是物质颗粒的沉积，同时也是地质信息的沉积，局部地质体可以包含其所在整体的大部分甚至全部信息。
