Based on the effect of the sanding on the bradenhead, the ground flow pipeline gtv and surface equipment in high pressure and high gas rate well in west Sichuan, and combination with actual engineering geologic characteristic and operation status, the paper analyzed the influencing factor of sanding in the fractured well, and put forward the countermeasures to effectively prevent sanding.

川西坳陷致密砂岩气藏拥有大量的高压高产气井，支撑剂回流出砂问题比较突出。由于气井压力高、产量高、流速快，加砂压裂后常出现支撑剂回流出砂的现象，对井口及地面流程管线闸阀、地面设备造成强烈的冲蚀破坏作用，已经严重影响到气田高压高产气井的正常生产。

Construction bucked the trend, up 26 per cent, due in part to a strong pipeline of housing projects.

Cabinda from Angola before a 300,000-ton Hong Kong tanker smoothly into Hong Kong, will be 17 million tons of crude oil through the oil boom and the success of terminals outside the pipeline dumping oil into the oil depot in the original.

日前一艘来自安哥拉卡宾达港的30万吨级油轮顺利进港，将17万余吨的原油通过输油臂和码头外输管道成功卸入油库原油罐中。

For supporting the building of the Pudong Expo area gas four tenders 26 road sections of 20,028 meters of gas pipelines and Puxi Expo area 8671 meters of road works Expo Gas calandria calandria local gas pipeline work in more than a year of intense work after the Recently all be completed.

对于浦东世博园区燃气配套建设4个标段26个路段20028米的道路燃气管道和浦西世博园区8671米道路燃气排管工程的世博园区内燃气管道排管工作在经过一年多的紧张工作后于近日全部竣工。

Some countermeasures are taken to solve the problems, such as the smaller pipeline diameter (108 mm), poorer water quality, more serious scale deposit and lower pump capacity, which are resulted from the panel cooler for concentrated sulfuric acid (32m2) instead of the calandria type cast-iron cooler for enlarging productive capacity (from 20kt/a to 40kt/a).

在硫酸装置扩能时(由20 kt/a改为40 kt/a)，选用板式浓硫酸冷却器(32m2)代替原铸铁排管冷却器。使用中发现管路直径偏小(￠108mm)，水质差结垢严重，硫酸泵扬量选择偏小等问题。提出改进措施。

It is shown that deformation temperature is the main factor that influences the static recrystallization behavior. Carbonitride precipitation inhibits recrystallization and causes a plateau in the softening ratio curve. The static recrystallization activation energy of X80 pipeline steel was regressed and calculated to be 380 kJmol^(-1), and its rationality was also discussed according to previous references and investigations.

结果表明：变形温度是影响奥氏体静态再结晶行为的主要因素；微合金碳氮化物的析出抑制了再结晶的进行，使软化率曲线出现了平台；利用实验结果回归计算出了X80管线钢的静态再结晶激活能为380kJmol^(-1)，并根据文献研究讨论了结果的合理性。

In near-neutral pH solution, the cracking mode is transgranular with the feature of quasicleavage.The function of SCC factors are as follows:(1)The additional potential takes an important role in the SCC behavior of X70 pipeline steel: the susceptibility to SCC increased with decreasing cathodal potential,HIC is the dominant reason,the crackles on the surface are almost vertical to stress;On the country, at anodic potential,there is a critical potential,below which the dominant reason is anode-dissolving supported by hydrogen,and the crackles on the surface are not vertical to stress.

电位因素和环境因素的影响作用为：(1)在阴极极化电位区，SCC敏感性随电位的负移而增加，氢致开裂作用占主导，表面裂纹多与拉应力垂直；在阳极极化区间，存在阈值电位，低于阈值电位时，SCC为氢促进阳极溶解所致，表面裂纹多与主应力方向成一定角度。

As important approach to pipeline reliability is cathodic protection.

阴极保护是保持管道可靠性的重要方法。

The coating and the cathodic protection are two important parts of buried pipeline system.

防腐蚀层和阴极保护体系是埋地管道系统完整性的重要组成部分。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.

自从我们的世界一直是世界原生森林被任意剥削人。
