Horizontal well production technology without well-pulling job in Shengli oilfield
Keywords:
Application; Horizontal well; Oil recovery; Pipe string; Test; Water detectingAbstract
A new horizontal well production technology without dismantling well head and pulling up string to find water and test is introduced which can decrease operating times and cost. The pipe string includes double hydraulic cylinder with anchorage packer double hydraulic cylinder without anchorage packer releasing too reversing valve and centralizer. The results of tests show that the technology pipe string is advanced and reliable and has an obvious social and economical benefit.
