Description
Technical field
The present invention relates to petroleum, gas drilling, complete well, well workover or production fields, more particularly, to one kind for managing
The bearing assembly of column.
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 (being also packer) and its setting tool (being also set packer) be sealing sleeve pipe with
The annular space of sand control pipe (top packer) (sand control pipe is also tubing string) hangs sand control completion tubing string, is gravel filling
With one of key tool in 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 due to pin or to break part bearing capacity poor, and packer often carry it is heavier, therefore, in tripping in process
Middle pin breaks the easy disconnection of part, leads to premature setting.
Summary of the invention
