In the period of Middle N2,the source rocks with higher maturity of Middle Jurassic in Saishiteng sag originated expulsion of hydrocarbon followed by migrating into the deep layer(>1 000 m) of Well Mabei-1.In the Late Himalayan movement,the whole Mahai swell was uplifted,featuring fixed traps and shallower reservoirs.
4. The comprehensive prediction technology for natural gas enrichment belt of super tight reservoir in deep formation, the recognition technology for fractural reservoir and gas prediction geophysical method & technology have been developed and formed.
Deep submicron process technology is widely being used and interconnect structures are becoming more and more complex.
Analysis of armature reaction and winding inductances of permanent magnet brushless DC motor with deep slot concentrated coils
The two forests differ in forest humus layer; it is deep in the Ailao forest while little is present in the Xishuangbanna forest.
Based on a detailed investigation of vertical distributions of fine roots in Robinia pseudoacacia plantations at the Ansai Soil and Water Conservation Station, Shaanxi Province, a model was developed for the deep distribution of fine roots of R.
pseudoacacia, which reflects the growth of fine roots affected by the mixed process of infiltration water and deep soil water.
Considerable alteration of these limiting agrochemical and biological soil properties (in the variant with NK application) leads to the soil degradation not only in the plow layer but also in the 1-m-deep layer.
Relative elevations of different elements of the microtopography and the soil bulk density values within the 2-m-deep layer have been measured at the same points, and the relationship between these characteristics has been analyzed.
The soil structure and the water stability of the soil aggregates in the upper 30-cm-deep layer have improved.
Wave equation wave field numerical modeling technology is applied to the observation that deep layer imaging is difficult below a screening layer of high-velocity basalt.
A three-dimensional baroclinic shelf sea model's numerical simulation of the South China Sea (SCS) middle and deep layer circulation structure showed that: 1.
In the case of beech without a red heart, because of the high portion of inhibiting elements, such a deep zone of inhibition is formed in the concrete, that the concrete-relief picture barely shows any structures.
The results show that the volume fraction of red-stained (PAS-positive) material, as well as the frequency of occluded glomeruli, are similar in the superficial and the deep zone.
MR microscopy studies of the cartilage at the 12-week time point also found a trend toward longer T2 values and reduced anisotropy in the deep zone of the OA cartilage, consistent with increased hydration and less ordered collagen.
collected in a 80 to 120 m deep zone close to Barcelona (Spain) during the months of February-March 1981 were measured by atomic absorption spectrophotometry after subacute (10 ppm Zn for 3 wk) and acute (80 ppm Zn for 24 h) treatment with ZnSO4.
Caves of an early stage were formed within a deep zone of low thermal gradient.
These processing techniques have been applied for the first time to land seismic data from Liaohe areas, resulting in greatly improved quality of the deep formation and better imaging of the shallow layer obtained in the volcanic-shielded area.
Atacamite in the oxide zone of copper deposits in northern Chile: involvement of deep formation waters
Its viscosity and density are much lower and, under injection pressure in the deep formation, it may be under supercritical conditions.
Polymer solution is widely applied to resolve the water-channeling problem in a deep formation.
In practice, polymer is used in deep formation treatment either to form a gel blockage and plug high permeability zones in situ, or to act as a mobility control agent and increase the viscosity of injected fluids.
