According to gathering plentiful relative datum of of Xuer section of Yazihe structure and seismic、 well logging、 surveys、 core ect during the exploitation and exploration,the research starts with analise of slice data、 core observation and core specimens,then combines with coordination、 analyse、 concluding and the former research result.The article recognizes the tectonic feature of Xuer section of Yazihe structure and it"s tectonic evolution,analyzes the distributing feature of oik、 gas、 water、 their dominated factor、 the pressure feature of gas reservoir and especially the conservative condition of Xuer gas reservoir.At the same time,the article acquaintances the depositional feature and sedimentary environment and discusses the main genesis typeof reservoir sandstone.By analyzing the physical feature and physical relation of reservoir rock, the article first classifies and evaluates the reservoir rock simply ,then concludes it"s feature of reservoir and permeability. According to detailed core observation and fracture explanation in well logging ,the article uses single well fracture indentifying and evaluation to confirm the section where the fracture growths,putting emphases on the method to get parameter of fracture,such as fracture width and fracture porosity.Finally,combining with the principal curvature for tectonics deformation the article predicts the plane fracture of reservoir and weave the general evaluation map of crack fracture growth.

Based on a quantitative analysis of radiolarian in 80 surface-sediment samples from the northern area of Okinawa Trough, this paper reported the species composition and faunal assemblages characteristic of radiolarian, expounded the distribution pattern of radiolarian abundance and diversity in surface sediments from this area. In this paper, a preliminary study on the relation of the distribution and abundance of radiolarian to environmental factors, such as chemical and physical properties of the overlying masses (sea-surface temperature, salinity, nutrients and primary productivity) and the type and composition of sea-bed sediments was made. The radiolarian data was evaluated using a Q-mode factor analysis to identify different faunal assemblages and their geographic distributions, then the relationship between radiolarian assemblages and distribution of water masses, hydrographic boundaries such as frontal systems was analyzed. A new radiolarian-based transfer function to estimate mean-annual sea surface temperature and seasonal range were examined to test its success in the study area.

本文对冲绳海槽北部80个表层沉积样品中的放射虫进行了系统鉴定和定量统计，研究了放射虫的种类组成与类群特征以及其丰度和分异度的分布；分析了海水温度、盐度、营养盐以及沉积物类型、成分等环境因素对放射虫分布的影响；采用Q-型因子分析，求得放射虫的属种和组合分布特征，探讨了放射虫组合与不同水团、海洋水文结构之间的关系；并对Pisias（1997）建立的估计表层海水年平均温度和其变化范围的放射虫转换函数在研究区的适用性做了检验。

Based on scene X fluorescence analysis ray fluorescence , X of sea floor , that principle develop survey system can go on normal position survey to the sediment in sea floor, can carry on non- destructive analysing to the sediment of sea floor that is gathered fast on the ship too, mineral products reconnoitre or environment investigate in time submitting necessary information for marine.

基于现场X荧光的分析原理研制的海底X射线荧光探测系统可在海底对沉积物进行原位测定，也可以在船上对采集的海底沉积物进行非破坏性的快速分析，为海洋矿产勘察或环境调查及时提供必要的信息。

After comparing the examination result with the common biological indicators, we notice that the organic substances in the samples collected from the mud volcanoes mainly come from land higher plants and the result of the redeposit after washing out the upstream's deposit, this conforms the geographic location in the mountains and the luxuriant plants in the region, hoping this research result can provide reference values for the future land developers, in order to take advantage of the land as much as possible, aw well as a perfect planning and conservation of the mud volcano.

将检测结果与常见的生物指标比对后，发现所取泥火山样品中所含的有机物质主要来自於陆生高等植物及上游沉积物经冲刷后再沉积的结果，这和泥火山的地理位置位於山区且附近植被茂盛是相符合，希望这样的研究结果可提供将来土地开发者参考，对这块土地做最好的利用，并对泥火山做完善的规划与保留。
