Description
Technical field
The present invention relates to petroleum, natural gas sand control completion field, more particularly, to set packer on sand control pipe and packing
The connection structure of device.
Background technique
Loose sand oil-gas reservoir is extensive in distribution on global, such oil reservoir is due to burying shallow, loose cementation, pole in production process
Easily shake out.Gravel filling and simplified sand control are two kinds of major ways of current sand control, and gravel filling sand prevention is with ground sand-preventing pump
Certain density mortar is pumped into well from drilling rod, screen casing and casing annulus and Perforation are entered by selective crossover tool
Road, until covering entire sand control section, load fluid flows through screen casing and returns to ground or enter stratum with gravel, and simplified sand control is then not necessarily to
The filling of mortar is carried out, it is eased.
The main function of top packer (one kind of packer) and its setting tool (being also set packer) is sealing sleeve pipe
With the annular space (the mainly packer of sealing sleeve pipe and tubing string) of sand control pipe (sand control pipe is also tubing string), sand control is hung
Completion tubular column is one of key tool in gravel filling and simplified sand control technology.
Existing setting tool is connected by pin with packer or is connected by the very low part of breaking of a pull-off force,
Bearing capacity is poor, and the mode of slipping out of the hand is above to mention setting tool or suppress, and breaks the pin of connection or breaks part, by setting tool
Separated with packer, due to pin or to break part bearing capacity poor, and packer often carry it is heavier, may be in setting process
In slip out of the hand in advance, so that tubing string be made to can not work normally.
Summary of the invention
