Though application of remote sensing for oil exploration is still in stage of enriching and developing, the ten-year practice has shown that remote sensing takes advantage in the research of petroleum geological factors and the selection of efficient target areas for exploration. It can also contribute to forcasting the new oilfields by analogical analysis of remote sensing information features of the known oilfields.展开更多

The enhancements of the thermomechanical performance of bulk diamond compacts in terms of hardness, fracture toughness, wear resistance, impact strength, and thermal stability are our project objectives. It is to aim at applying an advanced nanosynthesis process for the manufac-turing of superhard and ultratough diamond/SiC nanocomposites with the implementation of nanofiber reinforcement. The R&D re-sults can be used in multi-industrial applications, particularly, for drill bits designed to encounter dynamic impacts for high speed oil/gas drillings, thus to achieve high efficiency and energy saving. Science and technology (S&T) researches on precursors, cata-lyst, reactive sintering, and in-situ/real-time characterization of high P-T neutron/X-ray diffraction studies on phase stability, syn-thesis kinetics, residual strain, and yield strength have been applied to help optimizing the nanomanufacturing process. Our R&D ef-fort in high P-T nanosynthesis of TSP diamond/SiC composites is to achieve superior performance of nanomechanics in resisting dy-namic impact and thermal degradation, while still maintaining the super-hardness and super-abrasiveness of diamond and silicon-car-bide. The improved polycrystalline diamond compact (PDC) bit inserts for drilling, boring, and cutting will be applied in harsh envi-ronments so as to meet the demands of the mining, petroleum, and machinery industries. With success of the proposed project, the expected energy savings and reduction of CO2 emission will be significant and the economic advantages are going to be enormous.展开更多

Inspired by earlier western studies on the theme of enforcement style,this article proposes a creative dimension for analyzing enforcement styles. It is suggested that enforcement styles comprise the degree of formalism,the degree of coercion,and the degree of willingness to enforcement. The second contribution is in showing the relationship of different types of enforcement styles to the three dimensions. In addition,we analyze the enforcement styles in the sector of pollution control of petroleum industry based on the refined hypothesize and draw out lessons to be learnt.展开更多
