Large displacement wells, horizontal well casing, dogleg degree, generally continuous adjustment of the position more, the casing into the generally quite difficult, if not in place in the casing since the casing is very difficult, the generalhave to cementing in place, the loss of large segments of the middle layers. Therefore, in order to ensure the safety of the casing down into the next casing when must be considered to reduce the positive pressure of the lower part of the casing of the borehole wall, reducing the casing into the friction and ensure smooth casing down into the.
      Shengli Oilfield professional floating casing, the lower part of the casing at the air full of state, greatly reducing down into the resistance. The process is characterized by: the process is simple, easy to operate, leading technology. Suitable for 7 ",5-1/2", 9 5/8 "casing of the various types of single well service charge of RMB 350,000.
