With the analysis of cluster and correlation,this paper finds a polynomial connection with one unknown and quadratic expression existing in interlayer pressure difference, interlayer thickness and cementation factor of cement BI, which is used to appraise the quality factor of well cementing.

Different sedimentary facies zones have different water absorbing rule during waterflood development and water-drive reservoir is constantly flushed and reformed,which made the sedimentary facies zones,having good physical property of reservoir,more apparent by waterflood reform action and led the interlayer difference in waterflood input wells to gradually become larger.

Determining the anisotropic parameters of fractured formation by using P-wave interval moveout;

,Ltd suffered excessively high bed pressure differentials.

For these,through adjusting the pressure difference of material layer,improving the matching ratio between primary air and secondary air,making the bed temperature in boiler to be enhanced,and the combustion condition to be improved.
