Finally some tentative research in actual TEM curve inversion with this artificial neural network(ANN) expert system has been done which with the union of known drill hole and the electricity log information, and has made the inversion results and the traditional inversion methods results the comparison and has carried on the preliminary error analysis and the appraisal.
In order to set up stratigraphic succession of the Hexi Corridor, a stratigraphic division has been made on the basis of the characters of magnetostratigraphy of the Q y1 Drill Hole of Jiuquan, the achievement of test of heat releasing light, the data on 14 C and the characters of litho stratigraphy.
The paper briefly describes the genesis and ore formation mechanism of paleochannel sandstone type uranium deposit in Nuheting area. Techniques such as remote sensing digital image data processing and data enhancement, as well as 3 dimension quantitative analysis of drill hole data are applied to extract information on metallogenic environment of paleochannel sandstone type uranium deposit and the distribution of paleochannel.
This method had been used in different area and different types of gold deposits. The high-density resistivity anomaly is suit well with the practical deposit body in site. In some unknown area, unknown deposit bodies were found underground 38 meters by QZ14-2 drill hole.
Investigation about Buried Depth of Up-breakpoint on the Normal Buried Growth Fault——Taking Bore Hole Composite Profile of Buride Fault in Yinchuan as an Example
Sediment mass volumes for periods since the Oligocene (E3, N11, N12, N13, N2, and Q) in the South China Sea (SCS) were calculated on the basis of geological and geophysical data including ODP borehole data.
The concept of additional mud cake formed by the effect of cushion at the bottom of borehole during pouring concrete is introduced to explain the mechanism of end effect on skin friction of the bored pile.
The resulting force vector of the suture located between the anchor and the drill hole was close to the anatomic force vector of the coracoclavicular ligament complex.
There existed significant differences in serum levels of CEA, CA199, CYFRA21-1, NSE, and SCC-Ag among different Ccr groups and the markers bore a negative correlation with Ccr.
A study is made of the formation of a shock wave (bore), produced by the movement of an initially weak discontinuity in the spatial derivatives of velocity and liquid depth in an area of stationary current in a channel of constant inclination.
The heat flow values calculated in this paper and from petroleum bore hole in East China Sea shelf are much more close to that in southeast China than in Okinawa Trough.
Sheyang Lake was once in ancientry the largest lake in the north Jiangsu Plain. It was deep and vast, and swarllowed the water drainaging from Yongzou, Xinghua, Gaoyou, Baoying, Taizou, Yangchen regions and flowed eastward to the Yellow sea. From the Spring and Autumn period to the North Song Dynasty, it was the transport way between the Changjiang River and the Hueihe River. After 1128 A. D. (the Huanghe River flooded southward and deprived the lower Harihe River), the Huanghe River overflowed and bursted ...
The Zhangzhou Geothermal Field is one of the highest temperature geothermal fields so far discovered on SE coast of China. Geological, geochemical and temperature pattern studies indicate that the Zhangzhou Geothermal Field belongs to a deep circulating thermal water field of convective type. For calculating the circulation depth of thermal water, a cylinder model was applied in the study. Firstly, the upwelling flow rate of thermal water along the cylinder was calculated from the temperature measurements i...
In the Southern Hemisphere summer of 1985-1986, several shallow boreholes (mostly 10 m and deeper) were drilled on the glaciers in Nelson Island and King George Island, which are near the Great Wall Station, Antarctica. Temperature measurement in them
