Requests on resistance of corrosion destructibility of sealing interfaces that related to sealing up and cementing exercises in petroleum engineering are more and more of rigidity. It is urgently needs to resolve all sorts of problems that affect interface bonding quality. Conventional cement slurry design resist the destructive function worse, and can't like to satisfy the request to carry on latter production such as perforation, acidify, fracture etc.

常规油井水泥抵抗破坏的性能较差，不能很好满足水泥环抗冲击振动以及射孔、压裂等各种变形破坏的要求，这在一定程度上限制了小间隙、大位移、定向与水平井等特殊钻井工艺技术的发展，也制约了后期压裂、酸化等诸多开发工艺措施的实施。

However, development of cement industry will also face disadvantageous factors: 1 along with the coming of high cost epoch, continued rising in costs of coal, power, mineral resources, environment, human resource and capitals and the increase in social responsibilities that enterprises should take on will bring restricting factors to the investment and development of cement industry; 2 on the basis of the gradual increase of industrial concentration, market competition will change from the current competition between large enterprises and small enterprises and between new dry process and backward shaft kiln technology to the competition among large enterprises and among new dry processes, so the extent of market competition may further extend; 3 along with RMB increasing in value, demand decreasing in north America, new production lines in Middle east being put into operation and the persistent high price of international shipping, national cement export will face huge menace; backward flow of export products will certainly aggravate market competition in some areas.

但水泥行业的发展也将面临不利因素。一是随着高成本时代的到来，煤炭、电力、矿产资源、环境、人力、资金等成本的不断提高及企业所承担的社会责任的增加，将对水泥工业的投资和发展平添抑制因素；二是在产业集中度逐步提高的基础上，市场的竞争将由目前大企业与小企业、新型干法与落后立窑工艺之间的竞争转为大企业与大企业、新型干法与新型干法之间的竞争，市场竞争的程度有进一步加大的可能；三是随着人民币的升值、北美市场需求的下降、中东新生产线的投产及国际航运价格的居高不下，我国水泥出口将面临巨大的威胁，出口产品的回流，势必将加剧局部地区的市场竞争。

Optimal mixing ratio of SRA as delay forming agent in cement treated base is 0.05%-0.06%; the influence of compacting delay on strength and dry density of road base may be reduced by SRA additive, forming time may be delayed to 9h; after the forming time is delayed to 4h, 6h and 9h, the strength and dry density shrinkage of cement-treated base with SRA admixture are much less than that of those without SRA.

SRA用作水泥稳定粒料路面基层的延迟成型剂的最佳掺量在0.05％～0.06％：用SRA可降低因延迟压实对水泥稳定粒料基层的强度和干密度的影响，可把延迟成型时间延长到9h；在成型延迟4h，6h，9h后，掺入SRA的水泥稳定粒料的强度和干容度损失明显小于未掺外加剂的混合料在相同延迟成型务件下的强度损失。
