We have concluded five key tectonics geologic characteristics of Chinese foreland basins based on the study of the sedimentary infill, tectonics evolution, tectonic dynamics, spatial location distribution and structural deformation geometry.(1) The foreland basin is the superimposition of the compression sedimentary stratigraphic sequence with the extension basin, and the foreland basin includes underlying rift basin and upper dustpan flexure deposited basin.(2) The foreland thrustfold structural deformation has occurred four times since the Protozoic, in the Late Caledonian, Late Hercynian, Indosinan and Late Himalayan, respectively.(3) The foreland basin developed based on the control of two factors that are the basin basement collaged by many small plates or terrains and the rejuvenation of ancient orogenic belt, so the foreland basins or foreland thrusts are located in front of ancient orogenic belt.(4) The foreland basins and the rejuvenation of ancient orogenic belt make up a giant basinmountains system resulting from the distant effect of IndiaEurasia collision, which is located on the outer circle of Tibet Plateau, so the thrust deformation intensity, basin deposition range and coupling between orogenic belt and basin changed from strong to weak as from interior to outer circle of Tibet Plateau.(5) There are many structural styles of the thrust and fold belt in different basins, such as brittle behavior faultrelated fold, ductile behavior basementinvolved structure, basementinvolved faultrelated fold, and salt structure.

欠平衡钻井过程中气层逐渐被打开时，气体将以小气泡的形式从地层进入环空流体中，气泡进入环空后将膨胀运移，变成大气泡，因此气泡生成半径对环空流体的流动规律有重要影响。

The average epoxy value and the average viscosity of such diluent were 0.502×10-2eq/g and 3.2 mPa.s(25 ℃) respectively. It was an ideal diluent and could be used instead of active diluent such as butyl epihydrin etc. and non-active diluent such as dibutyl phthalate etc. in epoxy resin industry. The preparation of the epoxy diluent by fusel oil could not only settle the problem of environmental pollution caused by fusel oil drainage, but also produce economic and social benefits.
