查询词典 guide casing

In the design of expension tool, the cone angle is the key, because it must satisfy the plastic extreme condition of the expension tube and reduce the upgoing frictional resistance of the expension cone to minimize the possibility of tool sticking. It is preferred that the material quality of expension tube must differs from that of casing and the yield limit of expension tube must be less than that of casing, which is favorable to protect casing.

在膨胀工具结构设计中，锥角设计是关键，除了要满足膨胀管达到塑性极限条件外，还应综合考虑膨胀锥上行的摩阻尽可能小，以减小工具卡死的可能；膨胀管的材质应与套管材质有差异为好，并且膨胀管的屈服极限应小于套管的屈服极限，这样有利于保护套管。

After 5~1/2" casing pipes having been corrupted and punched, Caiyou Wuchang in Zhongyuan oil field carried out well workover with 4" casing pipes, but it is impossible to pump with big pump and the pump setting depth is limited .Consequently, Caiyou Wuchang directly makes 4 casing pipes as lift pipe string without tubing to pump oil.

中原油田采油五厂原5 1/2&套管严重腐蚀穿孔，下4&套管修井作业后，无法在小油管内实现大泵提液，同时限制了下泵深度，因此，直接将小套管作为举升管柱进行抽油。

Bilirubin and heparin sodium etc. are also produced. The pigs ' intestines casing is mainly used in making sausage, ham, red sausage and other foods. The sheep ' s intestines casing produced in this factory casing can be used in medical, piano string and feather bat etc.

猪肠衣主要用于制造香肠、香肚、火腿、红肠以及灌制各种食品，羊肠衣除用于制造各种食品外，还广泛用于医学缝合线、钢琴弦、羽毛球拍等制线产品。

To prevent casing damage and expand well life, a thick wall casing, TP130TT of high collapsing strength was designed and developed, based on the analysis to the mechanical conditions of casing and its damaging tendency in the salt bed. The matching technology and tools were also developed.

因此 ，防治套管损坏，延长油水井寿命，已是中原油田当前亟待解决的问题。1 油水井套管损坏的主要原因由于中原油田是一个复杂断块油气田，不同的区块和同一区块的不同部位，套管损坏的规律和造成套管损坏的因素都有很大的差异。

The casing strength design charts presented by this paper can be used to check the safety of the casing in salt bed or help perform casing strength design when the load is known.

可用来检测盐岩等流变地层中下入套管的安全性或在已知套管外载时进行套管强度设计。

Most casing damages in Zhongyuan oilfield take place in the salt bed formations, and this has remained a problem that seriously threatens oil and gas production for long time. Causes of casing damages were investigated, and a series of measures in casing design have been adopted accordingly, but with unsatisfactory results.

中原油田由于地质结构复杂，断层纵横交错，油气埋藏深，又有多套盐膏层覆盖，再加上注采关系不够平衡，导致了一大批先期投产的油水井套损现象十分严重，这不仅造成了巨大的经济损失，而且破坏了注采关系，大幅度地降低了油气产量。

Don not attempt to do something which you can not to do.

不要企图做那些办不到的事情。
