According to the facies' distribution and structural features,it is predicted that the fine reservoir of type Ⅰ is mainly located along the pinchout boundary of the research area,and the main trap type is structured-iagenetic.
The oil distribution rule of oil and gas in the Tertiary basin of Chaidamu was studied by using the model of the terrigenous sequence. The arrangement relation of the sedimentary system in different system of the sequence and the source reservior cap combination and the distribution of trap type were discussed.
Through analyzing the distribution of the discovered reservoirs and the characteristies of different types of traps, the authors consider that the Kungurian FM salt bed played a key role in the process of reservoir formation throughout the Basin, especially to the reservoirs above Kungurian FM.
Deep-water exploration has 5 characters,which include that basin types are dominated with passive marginal basins,exploration zones are mainly in extended deep-water zones with oil-bearing zones in shallow-water,types of traps are mainly of large structures,and reservoirs are high permeability reservoirs with tertiary deep fans,oil type is dominated with oil.
Thefault activity controls the types of traps, the fotmation and distributionof the secondary structure zones, the distribution and, moving of thesubsiding center and the zones of sedimentary facies, and the maturity,migration and acctimulation of oil and gas.
The Silurian hydrocarbon accumulation of Tazhong area is characterized by no highness in abundance of hydrocarbon accumulation, coincidence of thin layers with large distributive area, and control of several types of traps.
This research know distribution and connectivity of the sand layer by the study of division and correlation of substrata, and effective analyze the distribution of gas pool, disciplinarian of gas and water, heterogeneity, condition of reservoir, making hydrocarbon, caprock and the type of trap in the whole field.
The effect of funnel trap type and size of pitfall trap on trap success: implications for ecological field studies
johngarthi consisted of males with a carapace width (CW) >amp;gt; 125 mm and, depending on the trap type, relative abundance values from 0.05 to 1.2 crabs per trap-hour.
The effects of dispenser type, dispenser aging in the field, pheromone dose in the dispenser and trap type on trapping efficiency of codling moth,Cydia pomonella (L.), males were investigated in Israel.
These young weevils are sensitive to other stimulus and it is may be, only by chance, that they are found in this trap type.
The white sticky trap type Rebell bianco was the most attractive for B.
It is shown that the carrier transport in a high-resistivity (a-Si:H):Er film (resistivity ～109 ? cm) proceeds by the mechanism of unipolar-injection space-charge-limited currents controlled by two types of traps.
Trap parameters, namely, the densities and ionization energies of acceptor and donor centers (～1019 cm-3 for both types of traps; 0.85-0.95 eV and 0.4 eV, respectively) are estimated by analyzing the current-voltage characteristics.
Annealing at 100-250°C was found to result in the formation of two types of traps with the levels Ec-0.32 eV and Ev+0.29 eV.
Two types of traps are found, namely, traps for holes and electrons, whose density can be varied during deposition of the monolayer by the choice of intensity of illumination and by the method of passivation of the surface.
According to this model, two types of traps with binding energies of 2.4 and 4.1 eV are present in graphite.
The test of independence indicates that the sex ratio in the catches is independent of the type of trap, but dependent on the population.
Small traps were most efficient in catching small species, whereas large traps caught relatively more large beetles.4.The capture efficiency of each type of trap was tested in the laboratory, using six species of Carabidae.
To date, however, there is only one type of trap on the market in the U.K.
The former type of trap deployed over long exposure periods is therefore recommended as providing the best estimate of net downward particle flux in lakes such as Lough Neagh.
The degree of undercollection depends on the flow velocity, the type of trap, the height: diameter (aspect) ratio of the trap, and the type of sediment.
