     double stage casing head double stage casing head

In addition to all the features of single-stage casing head ,the double-stage casing head presents the following features:

Through putting the testing plug into 9-5/8 "hanger before pressure test of the third section drilling, Can be fully detected quality of the second section drilling.

The procedures and workforce of installing BOP can be shorten through Optimizing design of the casing head and the wellhead equipment can be installed at one time.

The protection sleeve of the third section drilling don?t have to be removed due to the optimum design of structure.

     Float shoe Float shoe

The float collar is mainly composed of spoiler, floating ball, shell and the basket. The casing float shoe is mainly composed of spoiler, floating ball, shell , the basket and guide shoe. The cone of spoiler center hole with floating ball can seal fluid reverse. The basket can support floating ball, flush well cycle and adjust performance of the drilling fluid . When cementing job,the basket support the floating ball and float collar is in the conduction state, so fluid can pass through freely. Float collar is back-pressure after running casing and the end of cementing job. Floating ball with sealing face of spoiler can prevent fluid backflow.

     Rigid casing centralizer Rigid casing centralizer

Spiral casing centralizer has the advantages of simple structure, safe and high intensity. It can be widely used in vertical, deviated and horizontal well in the construction work. Rigid spiral centralizer can improve the efficiency of well cementation through cement paste revolving when cement injection in the vertical well. Spring centralizer is unlikely to support heavy casing in the deviated and horizontal well, so rigid spiral centralizer is the only choice.
