Continuous oil tube fracturing and downhole throttling producing integrated process tubular pile and method thereof

Abstract

The invention discloses a continuous oil tube fracturing and downhole throttling producing integrated process tubular pile. The continuous oil tube fracturing and downhole throttling producing integrated process tubular pile comprises a continuous oil tube, a shearing releaser, a sleeve coupling positioner, a hydraulic ejector, a packer, a slide sleeve base, a hydraulic adding tool and a downholethrottling machine, wherein the continuous oil tube is connected to a hydraulic releaser through a connector; the lower end of the shearing releaser is connected to the sleeve coupling positioner; thelower end of the sleeve coupling positioner is connected to the hydraulic ejector; the lower end of the hydraulic ejector is connected to the packer; the lower end of the packer is connected to the slide sleeve base; the lower end of the slide sleeve base is connected to the hydraulic adding tool; and the lower end of the hydraulic adding tool is connected to the downhole throttling machine. Thecontinuous oil tube fracturing and downhole throttling producing integrated process tubular pile overcomes the defect that a gas well cannot perform downhole throttling at an early stage, gas well early-stage cost can be greatly reduced, liquid carrying ability of gas flow in a well shaft at the early stage is improved, and the yield increase effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of fracturing in oil and gas fields, and in particular relates to a continuous tubing fracturing and downhole throttling production integrated process string and method thereof, which are suitable for use in directional wells and vertical wells for casing completion. Background technique [0002] The downhole throttling technology relies on the downhole throttle to realize wellbore throttling and pressure reduction, and utilizes the technological principle of geothermal heating. This technology has been fully promoted and applied in the Sulige Gas Field. Practice has proved that this technology has the advantages of reducing costs, effectively preventing hydrate formation, and improving the liquid-carrying production capacity of gas wells. [0003] The slip type downhole choke widely used at present is to send the choke into the design position in the well through the well test wire, rely on the slips to loc...
