This paper uses quantitative evaluation method and principles of diagenetic reservoir facies,gray theory,matches and picks up petrophysical parameters,analyzes the comprehensive effect of evaluation parameters on diagenesis,establishes parameter index and automatic analysis and processing method for diagenetic reservoir facies evaluation with gray theory,integrates gray system theory and multi-information,and provides an important method and basis for reservoir description,heterogeneity study,oil well productivity analysis and screening favorable oil blocks.
The reservoirs are tight sand, with an average porosity of 4. 74% and permeability of 0. 417×10-3 μm2. Delta front underwater distributary channel and mouth bar are the favorable reservoir micro-facies.
Well Ht13, Ge11 and Ge13 wells newly drilled in advantaged gas detection area have obtained commercial oil-gas flow rather than Ht12, Ht205 and Ge14 wells outside the advantaged area, which support the reliability of this method.
In this paper, finally, combined all the research results in the paper with other information of hydrocarbon occurrence, trap types and the migration and gathering of hydrocarbon in Weibei depression, forecast and evaluate the advantageous bed sets and zones of containing oil and gas, and then point out serial advantaged exploration targets.
Under favourable structural and lithological conditions, this can lead to the formation of displaced oil-and-gas deposits, with oil enriched in light components.
The new method is of obvious economic advantage and favourable to decreasing surplus mud derived from adding Ca(OH)2 to precipitate Cr(III) traditionally so as to avoid recontamination.
However, in summer, the dipole blocking could be formed in the east part of the two oceans, and the heat source over the eastern part of two continents is favourable for the formation of dipole blocking in the east regions of two oceans.
Moreover, the two bacterial strains had favourable lytic effects not only on M.
This waste biomass, produced in high quantity in carefully controlled industrial processes, has certain favourable characteristics that may be improved for its usefulness.
Expanded cells from the coculture scheme appeared to be favorable for the second increasing of WBC in the transplanted mice.
It can be concluded that the existence of more Br?nsted acid sites was favorable for proton participation in the cyclization reaction.
This paper tested trace elements and vitrinite reflectance data from the the abnormal high pressure and normal pressure strata profiles, respectively, and found that the acidic and lower salinity starta are favorable for the increase of Ro.
The lower cooling number is favorable for the system, but it has an optimal value for a certain humidifier.
Out of the carbon sources studied, D-glucose and D-xylose were most favorable for the biosynthesis of xylose isomerase in E.
If species group III or II is the advantaged species in the shrub layer, the community would change from a coniferous forest to a sparse evergreen broad-leaved forest.
Moreover, by increasing the negative index, the width of defect layer and the numbers of period photonic crystal, the width of defect modes will be narrowed, which is advantaged to obtain optical filters with narrow band.
In this paper the position, advantaged and disadvantages of both HPLC and electrophoresis for the separation of amino acids, peptides and proteins in protein structure analysis are discussed.
On the base of the experimental phenomenon and failure mechanism for tube in tube structure specimen, nonlinear seismic responses analysis program on the basis of the advantaged element model for tube in tube structure is developed.
The results suggest that such resources operated more strongly for advantaged blacks than for whites.
