To resolve these problems, this paper deals with the technology of foamed acidizing. The anti-salt and anti-acid foamer DY-1+SJ-8 and foam stabilizer KMS-2 were selected, then their performance under different foamer concentration condition was evaluated and the proper concentration was determined. Thereafter the diversion experiment of foamed acid through the parallel core was conducted.

针对上述问题，对泡沫酸酸化技术进行了研究：通过室内实验筛选出了耐酸耐盐的起泡剂DY-1+SJ-8和稳泡剂KMS-2，并对不同起泡剂浓度下的泡沫酸性能进行了评价，确定了其使用浓度；在此基础上进行了泡沫的岩心分流实验，实验结果表明泡沫泡体可以增加低渗透岩心的分流量，减少高渗岩心的分流量，使泡沫流体在不同渗透率岩心内均匀推进。

Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.

因此，本文首先分析研究了PDC钻头的运动学和动力学，并利用分析的结果对PDC钻头的涡动是如何损坏切削齿的进行了探讨；在此基础上，进行了PDC钻头切削齿的受力实验，在受力实验研究中，不仅考虑了岩性、钻进参数、布齿密度等对切削齿受力的影响，而且考虑了切削齿不同的磨损状态、钻头的冠部形状对切削齿受力的影响；PDC钻头的切削齿是由聚晶金刚石层和碳化钨底层复合而成的，它的磨损特点既不同于金刚石的磨损又不同于碳化钨的磨损，因此，在分析了复合片磨损机理的基础上，进行了PDC钻头切削齿的磨损实验。

Therefore has carried on the next experiment: For the proof slip of paper dry scope migration is but because of receives the earth's attraction the influence to concentrate toward the slip of paper lower part, we have carried on the next experiment, we cut the slip of paper the long strip, then changes the level laying aside, because whether there is can't such slip of paper both sides underneath the space cause the hydro energy downward to concentrate create the experimental result the difference, after the experiment discovered, after has removed this difference, the slip of paper both sides dry need the time is nearly same, but according to above experiment, we arrived following conclusion, the slip of paper dry scope is downward moved from on downward migration because of the slip of paper in moisture content by the attraction attraction, causes under the slip of paperAbove the hydraulic modulus also must be many, above the natural slip of paper falls very quickly on the few water on the evaporation, but under many moisture content need more time can evaporate, causes the slip of paper dry scope most above downward to increase slowly from the slip of paper.

急！！！物理翻译中翻英请帮帮忙於是进行了下一个实验：为了证明纸片〈paper sheet〉乾燥范围的移动〈boundary of drying〉是因为受到地心引力的影响而往纸片下部集中，我们又进行了下一个实验，我们把纸片剪成长条状，然后改为水平放置，这样纸片两端就不会因下方有无空间使水能往下集中而造成实验结果的差异，实验后发现，去除了这个差异后，纸片两端乾燥所需的时间几乎相同，根据以上的实验，我们的到了以下的结论，纸片乾燥范围从上往下移动是因为纸片中的水分被引力吸引而往下移动，使得纸片下面的水比上面还要多，自然纸片上面就少量的水很快就蒸发掉，而下面较多的水分需要更多的时间才能蒸发完，使得纸片乾燥的范围从纸片最上面慢慢往下增加。

Co-firing characteristics of corn stalk and stone coal in different proportion were investigated by thermal gravimetric analysis. The results showed that corn stalk can improve the ignition and combustion of stone coal. The agglomeration experiments on corn stalk were made in a bench-scale bubbling fluidized bed with quartz sand as bed material and stone coal ash as additive. The results indicate that stone coal ash can inhibit agglomeration of bed material particles at temperature of 900℃. Agglomerate of blends was analyzed by means of scanning electron microscopy, energy-dispersive X-ray, and the bed materials were analyzed by means of X-ray fluorescence. Analysis showed that aluminum element and iron element in stone coal ash can react with alkali compounds and eutectics with low melting point, form a covering layer with high melting point on the surface of biomass and quart sand particles, thus inhibit the forming and transfer of low melting compounds.
