BUILT-UP STRUCTURE FOR PULLING THROUGH PIPELINES IN WELLS MADE BY METHOD OF HORIZONTAL DRILLING IN UNSTABLE EARTH |
摘要 |
FIELD: oil and gas production. ^ SUBSTANCE: built-up structure for pulling through pipelines in wells made by method of horizontal drilling in unstable earth consists of directing conductor connected with hole reamer via bayonet slots and dowels. In front the hole reamer is connected with a drill string, and behind it is connected with a pipeline through a rotary swivel. Strengthening mounting attachments are welded on bayonet slots to facilitate their durability. The bayonet connection disconnects the hole reamer with the directing conductor at a planned section and pulls the pipeline into the well by driving the drill string to rotation. ^ EFFECT: trouble-free pipeline pulling through in unstable earth and elimination of additional operations for assembly of devices. ^ 3 dwg |
