Research And Application Of Coiled-tubing Operation In Liaohe Oil Field

Coiled tubing is wound on the drum can be straightened out continuously from the wellor into a whole root unthreaded length tubing connection, the tensile strength of the cable isfaster than the speed ratio of the large drill pipe into the sky, because with the " applicationwidely, from the drilling speed, save time, and low overall cost,"etc. in the petroleumexploration and development is widely used, involves drilling, production and other aspects.This article is based on coiled tubing operations abroad cutting-edge technology and researchapplications in Liaohe Oilfield, Liaohe oil field exploration and development combined withthe actual demand for oil and gas production around the reality from the positive cycle waterjet pumps and connectors, tubing and no collar supporting tools, high-pressure piston pumpdeveloped, twin-tube test wellhead, twin-tube testing ground conversion device, injectionhead bracket and supporting device, supporting deeper drilling screw motor, extension rods,short drill collars, motor head, joints and other non-rotating tools parameter design, physicalmanufacturing, ground test start, synchronized with coiled tubing equipment to adapt to thetransformation process and to enhance SAGD test drilling devices supporting ground andthrough multi-site test wells to study the formation of coiled tubing with horizontal wellstested, coiled tubing deepen three technology and practices coiled tubing drilling andtransformation equipment.
