全面、系统地论述了处理剂和泥浆体系的关系；聚合物的使用浓度应突破全絮凝点，实现低固相应以发挥聚合物的抑制作用为主，絮凝作用为辅；影响钻头水眼处流动阻力的主要因素是泥浆中的固相含量、粒度分布及固相的亲水性，用η_∞代表钻头水眼粘度是欠妥的；聚合物泥浆处理剂的发展主要是开发新的单体和研究新的复配物。

They cationic monomer Acryloyloxyethyl ethyl trimethyl ammonium chloride and resource-rich, low price, low values of weathering burning coal as its main raw material, aqueous dispersion polymerization methods, through the weathered coal / cationic monomer in-situ polymerization in the international arena for the first time prepared by a high efficiency oil-bearing wastewater treatment agent; use of oil-field wastewater treatment, the waste slurry as raw material, has developed the world's first CWS dispersants and oil fields of the "three mining" using profile control plugging agent, in order to The high value of solid waste has opened up new avenues of applications; integration of related technologies, and open up for the oil field wastewater treatment, an annual output of 300 tons of sets of processes and devices for the first time realized the slop oil and drilling fluid back row of the industrialization of treatment .

他们以阳离子单体丙烯酰氧乙基三甲基氯化铵与资源丰富、价格低廉、燃烧值低的风化煤为主要原料，采用水介质分散聚合方法，通过风化煤/阳离子单体原位聚合技术，在国际上首次制备出高效含油废水处理剂；采用油田废水处理后的废弃物泥浆为原料，在国际上率先开发出水煤浆分散剂和油田"三采"用调剖堵水剂，为固体废弃物的高值化应用开辟了新途径；集成相关技术，开拓出针对油田废水处理、年产300吨的成套工艺和装置，首次实现了油田污油水和钻井返排液的工业化处理。

Clear water shall be used to mix both silica fireclay and clay fireclay into stable mortars with medium consistency and well service behaviors.

硅火泥和粘土火泥浆都需用洁净的水混练成中等稠度、工作性能良好而稳定的泥浆。

For, now, the last of the fleet of ships was round the last low point we had headed; and the last green barge, straw-laden, with a brown sail, had followed; and some ballast-lighters, shaped like a child's first rude imitation of a boat, lay low in the mud; and a little squat shoal-lighthouse on open piles, stood crippled in the mud on stilts and crutches; and slimy stakes stuck out of the mud, and slimy stones stuck out of the mud, and red landmarks and tidemarks stuck out of the mud, and an old landing –stage and an old roofless building slipped into the the mud, and all about us was stagnation and mud.

现在，那些急飞的舰队中的最后一支正绕过我们来时已经过的的低水湾，很快便不见了踪影；最后一艘满载稻草的绿色游艇、扬着棕褐色的风帆尾随其后，也很快消失了；只见几只装运沙石的驳船，形状粗糙得如同小孩们第一次学做的船舶模型，一艘艘低陷在泥浆里；一座支在桩上略显矮小的灯塔，像是踩着高跷、拄着拐杖的瘸子踏在泥浆里；泥滑的木桩立在泥浆里，泥滑的石头躺在泥浆里，红色的地标和潮标露出在泥浆里，一个破旧的码头和一座没有了屋顶的房子滑倒在泥浆里。

If the displaced fluid is thicker than the displacement fluid, the larger the difference is, the more the blending volume of displacement and displaced fluid is.

反之，顶替液的粘度越高两者的掺混量越少。因此，注水泥过程中前置液的粘度应介于钻井液和水泥浆的粘度之间。

The rheologic property of these cement paste s was measured by means of the rotary viscometer,the micro slump meter cone and vicat apparatus,and the mechanisms of the influence of the ratio of sulfate and alkali content on the rheologic property of cement paste were analyzed with petrographic analysis and SEM.

结果表明：对于高碱熟料，硫碱比过低会导致水泥浆体的流变性变差，其主要原因是煅烧熟料时液相黏度高将导致矿物晶体发育不完善、晶粒细小，水化加快。

The influence of activator of Alkali-activated slag cement on strength is studied.

本文主要研究了激发剂对碱矿渣水泥强度、硬化碱矿渣水泥浆体的孔结构及其水化程度的影响。

Rusults show that mobility of cement paste can be improved when steel slag is added to cement.

结果表明，钢渣掺入水泥中可以改善水泥浆体的流动性。

The problem of lost circulation in salt bed can be solved by using F27A anti-loss-circulation toughness reinforce agent for oil cement.

采用以F27A防漏增韧剂为主的多功能水泥浆体系有望解决易漏盐岩地层固井作业中相关技术难题。

According to the theorems of the particle composition and the high packing volume fraction, it is obtained a low-density slurry system by micro-silicon and drifting beads.

以紧密堆积和粒级级配理论为基础，研究出了性能较好的微硅－漂珠低密度水泥浆体系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
