Top Screen Pipe Cementing Technology in YM32 Well

The hydrocarbon zone pressure of Talimu YM32 wellblock is low and so does its stratum development well.When cementing the well,it often leaves the poor quality of casing and cementing slurry for serious oil pollution due to lost circulation,which seriously affects the later development of the block.Top screen pipe cementing technology can prevent oil and gas channeling after conventional cementing,prevent polluting wellblock's zone in the process of cement paste's loss and cementing,and help to find out the block's reserves better.Well cementing uses reasonable cementing technology and tools.The article introduces top screen pipe cementing technology including pipe structure,work principle and advantage of the technology.The successful application of the technology provides valuable practical experience for future similar cementing.
