The reason why no oil flow was found in these wells is that people had not ascertained the geological structure, trap type and lithology distribution in that area.
The controlling of tectonics for distribution of source rocks, types of traps, andtimes of hydrocarbon generation, migration and accumulation are obvious.
Imageries of structures in Sichuan basin clearly show that there exist different types of traps in the basin, characterized, vertically, by a general disconcordance in their configuration, location, size and elevation.
1. Stage of regional exploration: To investigate the geological conditions of a basin as a whole and the basic conditions for oil and gas formation in the region; to locate depressions favourable for oil generation and pick out zones favourable for its accumulation; and to predict types of traps that probably exist and make a preliminary estimate of reserve or resources in place.
The offshore oil and gas pools on the continental shelf of China are chara- cterized by their multiplicity of lithology, reservoir property and 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.
It has the character of multi type of trap,multi time accumulation oil,combination of reservoir cap rocks matched well with the time of trap close forming and oil gathering.
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.
Five trap types (colored stakes, inverted cone trap, Alsynite? impact trap, sticky window pane trap and reservoir trap) were evaluated for their capacity to trap adult O.
Comparative studies on the relative efficiency of two trap types for two allopatric populations of Glossina pallidipes in Kenya
The findings of these tests allow a choice among trap types and semiochemicals for cost reduction and convenience, but not for enhancement of the efficacy of the method.
In Newfoundland, the pattern of male captures in L and P traps was similar at both high and low temperatures, so competition between trap types would always be high.
The dominance structure of seven linyphiid spider (Araneae: Linyphiidae) taxa differed between the two trap types in wheat but not barley, although large differences were restricted to two taxa.
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.
