With the using of new full 3-D interpretative technology, the carefully interpretation of the micro ?amplitude structures and faults by the reprocessed 3-D seismic data in IES (Interactive Exploration System) interpretative system of Sun workstation is obtained. Because of the application of the well - advanced predictive technique for reservoir lithological changes, the predictive accuracy rate of drilling for 31 wells drilled in 1996 achieved 100% and the economic and social benefits are desirable. 相似文献

The practice has proved that it is an economic and effective method to investigate placer gold deposit by using multi-level information sources of remote sensing and multi-variate analysis methods, especially for the area with a sparse population and difficult condition like the Da Hinggan Mountains, China.The information sources used in our work includes Landsat TM, aerial infrared photography and their mosaic image maps and enlarged photos with different scales. According to statistic data, in the study area the gold-bearing rocks are mainly granite, alaskite, granodiorite and some old metamorphic rocks. On gold-bearing geological structures, the fault zones in the four directions (NE, NNE, NW and EW) are obvious, in which NNE and EW are the most key fault zones. On fluvial geomorphology the flow courses stored placer are in the tributaries of the 4th and 5th levels, especially in straight or slight curve reaches. On the basis of analysis the interpretative signs were set up, and the interpretative wo 相似文献

The identification and evaluation of oil reservoir with logging data are one of most important ways in geologic logging services. For the last decades, with the further development of the oil & gas exploration, great advances have been achieved in techniques on the acquisition, processing and interpretative evaluation of logging data. How to identify fluid characteristics and evaluate the productivity in light oil reservoir (the crude density being between 0.74g/cm3 and 0.82g/cm3)has become one of the difficulties.With the establishment of the regional interpretation criterion of the study blocks, the optimized logging parameters that reflect the reservoir characteristics have been used to establish the chart for the interpretation of oil-water reservoir combining with well logging parameters. Then, to begin with geologic reserves of crude in single well, we establish evaluation criterion for productivity in oil reservoir with determining lower limit value of the reservoir and applying the relationship between chart parameters. The techniques are verified in production and get better effect.On the basis of the reservoir characteristics analysis of both basin A and B, We established the evaluation method of static productivity on light oil reservoir with getting quantitative evaluation parameters after quantitatively evaluating the date of core, pyrolysis chromatogram and gas chromatogram. It provides new technique 7 for new well interpretation and old well review, as well as evidence for project.design of well testing. 相似文献

The Liaoji Proterozoic rift is an inter- intracontinenatl rift developed from Archean granite- greenstone tectonic regime and contains many important mineral deposits of U, B, magnesite, Pb - Zn, Au, Ag, Co and P. These deposits were formed as the result of late mobilization, transportation and concentration of the previously enriched ore - forming materials in several ore- bearing formations formed during the rift stage. So the metallogeny of these deposits in the rift shows both inheritance and new generation of the ore - forming materials. In future ore - searching practice, attentions should be paid on the studies of the ore - bearing formations in the rift, on the multiple stages of metallogeny and and on multiple derivations of the ore - forming materials. 相似文献

The release behavior of inorganic nitrogen and phosphorus in sediment during disturbance 总被引：1，自引：0，他引：1
Sediments and surface water were sampled in a tide flat in the Huiquan Bay, Qingdao, China in January 2004 to simulate the exchange of NH4-N/NO3-N/ PO 43- between sediments and surface water. A working system was designed with which samples were shaken at 60, 120 and 150 revolutions per minute (r/min). Experiment results show that NH4-N concentration in water at shaking rate of 60r/min decreased gradually, while at 120r/min increased gradually. In resuspension, fine-grained sediments contributed most NH4-N to the seawater, followed by medium-grained and coarse-grained sediments. The NO3-N concentration in water had a negative relation with the shaking rate; the medium-grained sediments contributed more NO3-N to seawater than the coarse-and fine-grained sediments. The PO 43- concentration is positively related with the shaking rate, the fine-grained sediments were the main N and P contributor to the seawater, followed by medium-and coarse-grained sediments. 相似文献

美国1892年伊利诺斯中央铁路司诉伊利诺斯州案确立了公共信托理论对限制政府处分公共信托资源之权的法律地位。借助于司法判例的解释功能,该理论扩大适用于美国渔业管理领域并形成相对稳定的基本内涵。有限介入权作为平衡公共渔业权与个人渔业权的制度工具,业已发展成为破解公地悲剧的重要手段。我国渔业权和海域使用权制度旨在特定海域赋予单位或个人有限期的捕捞权和养殖权,但不如有限介入权更能科学地界定渔业产权。有限介入权之合理性和制度价值当为我国立法所大胆借鉴,构建起我国渔业管理的创新机制。 相似文献

Foreign direct investments (or FDIs) have been employed since the early 1980s and they have become more and more important
in Chinese economic development. However, the roles of FDIs are very different between regions, partly due to the different
locational preference of various source countries. Some facts show that FDIs from Hongkong - Macao indicate a strong locational
preference. Therefore, this paper attempts to make an empirical research on the locational preference of Hongkong - Macao’s
FDIs and their spatial diffusion under the support of statistical data with regression analysis. In this paper, three statistical
models, including the special location model, the general location model and the spatial diffusion model, are created. The
results show that this kind of analysis is successful. The major conclusions are as follows. (1) The optimum location for
FDIs from Hongkong - Macao lies in the coastal area, especially Guangdong, Hainan, Jiangsu, Shandong, Fujian provinces. Besides,
Hubei Province is also an important region. (2) The FDIs from Hongkong - Macao in China have diffused gradually from the coastal
provinces to the inland regions, the northern and the metropolis and from the locations that had attracted a large number
of investments to their vicinities since the 1990s. (3) The special location factors, such as the border effect, the unique
social and kinship ties are the key factors determining the special locational distribution. (4) The general location and
spatial diffusion of Hongkong - Macao’s FDIs are the results of interplay of several economic factors. They are the economic
scale and advantage, the growth rate, the labor force and economic extrovert etc. 相似文献

通过对云南地区43个GNSS连续站2011-01~2018-12站点位移时间序列原始数据进行深加工处理,在计算应变参数格网时间序列的基础上,分别提取适合云南地区M≥5.0地震短临预测的面应变及最大剪应变短临异常指标;并基于其间发生的27个M≥5.0地震,采用R值评分法对异常指标进行预测效能评价。结果表明：1）两种异常指标对云南地区M≥5.0地震的发震时间具有较好的指示意义;2）当预测窗长设置为30 d或60 d时,在相同预测窗长下,最大剪应变短临异常指标的预测准确率高于面应变短临异常指标;3）通过对同一异常指标进行不同预测窗长的对比发现,面应变短临异常指标的最佳预测窗长为90 d、最大剪应变短临异常指标的最佳预测窗长为60 d（对于27个地震,二者预测结果均为：报对23个,漏报4个,预测准确率为85.19%）。 相似文献

山东省还没有发现过独立的铂族元素矿床，但在济南历城铜镍矿床中存在可回收的伴生铂族元素。在众多的中生代金矿床中铂族元素常常出现，虽然还没有经济意义，但可作为寻找新的铂族元素矿床的线索。根据近年来国内外铂族元素地质找矿与成矿理论研究的新进展，在山东寻找铂族元素矿床是值得注意的。山东可能存在多个时代(太古宙、元古宙和中生代)的成矿作用，矿床类型也可能是多种多样的，如与基性一超基性岩有关的济南历城式铜硫镍化物型矿床、与金伯利岩筒有关的铂族元素矿床和热液成因多元素组合的铂族元素矿床等。 相似文献
