The tribological behavior of different fraction diesel separated with distillation method was investigated and the lubricating performance of different polar diesel separated with chromatographic column separation method was evaluated.
Under the same condition of feedstock,TSRFCC technology could increase the processing capacity about 12%,improve the liquid yield 1.24 percent and decrease the loss of dry gas and coke 1.55 percent.
Experimental results show: ⑴Acidification can reduce the CODcr value and the content of suspended solids, and it also can play a good role in demulsification.
2, developed a high-sensitivity sensors for high-precision technology core "gaseous hydrocarbon sensor testing device", the equipment can also measure multiple parameters gaseous hydrocarbon micro trails content measurement accuracy can reach 10~(-11)grade.
It also shows that, near the wellbore and far from the wellbore, it displays two rectilinear with different slopes in ΔΔp-t log-log graph. The slope are (1-n_1)/(3-n_1) and (1-n_2)/(3-n_2) respectively.
Optimizing, combining and comprehensively applying the two series of technology can enhance oil recovery to a large extent ,at the same time , which can shorten the span of oil exploitation greatly and achieve more social and economic benefits.
Secondly, the effort of environment disclosure did by international and overseas governmental department are reviewed and at the same time a state of environmental disclosures is summarized synthetically.
The text analyses the existing models of pressure and temperature distribution ,applied formula solution ,deducted ordinary differential equation of pressure and temperature distribution , and programmed corresponding computer program ,at the same time ,used measured data to verify, drawing pressure and temperature distribution curve ,then applied Control Volume Method to calculate real pressure and temperature of variable-area oil tube , analyzed result .

It is an effective viscosity-reducer for the drilling fluid systems with different kinds and densities(1.04~2.10g/cm~3),and at the same time it can increase the inhibitory property of drilling fluid.
This paper reviews the drilling production practice of 48 cluster wells on AⅠ,AⅡ and B platforms of SZ36 - 1 oilfield pilot area , and introduces the experience of utilization of 9 items of key techniques to perform 48 wells drilling in 697 days with accumulated depth of 96 212 m,at the same time,indicates the problems which should be paid attention henceforth and the direction of effort in future.
The method applies to the standard arithmetic subgroups ofSO(n,1) (a case which was proved previously by Millson [Mi]), to the non-arithmetic lattices inSO(n,1) constructed by Gromov and Piatetski-Shapiro [GPS] and to groups generated by reflections.
We also show how to distinguish examples of open subsets with a good quotient coming from Mumford's theory and give examples of open subsets with non-quasi-projective quotients.
The cohomology algebra of the classifying space of a compact Lie group admits the structure of ann-Hopf algebra, wheren is the order of the Weyl group; the homology with dual structure is also ann-Hopf algebra.
The design that is subject to this criterion satisfies many kinds of linear optimal criterion and D-optimal criterion on several experiment models at the same time.
