Description
The invention belongs to from what the pump and the oil production technology thereof, particularly driving mechanism of depths lifting fluid rest on the ground and have earthward the free plunger of lifting fluid or the pump and an oil production technology thereof of piston.
When oil well pressure drops to forfeiture blowing ability, usually need to adopt the method for mechanical lifting that crude oil is risen on the ground, at present pistons or plunger upper part of adopting are that the rod pump of solid hopkinson bar or tubing pump and the oil-feed of employing center hole, looping pit are fuel-displaced more, the method of conversion of sounding producing fluid level and annulus logging is then adopted in the test of reservoir parameter, tie curedly, the dilution of the elimination of dead oil or viscous crude is then injected chemical agent or high temperature fluid by annular space to oil reservoir.The test method that sounding converts, there is double error, make the parameter error of acquisition bigger, annulus logging is not only because of easily to cause success rate low with the tubing string winding, and can not be used for inclined shaft, inject chemical agent or high temperature fluid by annular space to oil reservoir, cause a large amount of heat energy of waste and chemical agent.
For providing a kind of usability good, can improve the reservoir parameter testing precision and improve oil well pump and the oil production technology thereof of removing wax deposition, dead oil and dilution viscous crude efficient, hollow oil well pump and the hollow pump oil production technology of taking out are proposed.
Hollow oil well pump is by the pump barrel assembly, plunger piston assembly, advance, fuel-displaced one-way valve assembly and hollow shaft assembly are formed, the plunger pump assembly places in the pump barrel assembly, and on having, the central through bore of following perforation, the hollow shaft assembly places in the central through bore of plunger piston assembly, and on having, the central through bore of following perforation, advance, fuel-displaced one-way valve assembly is by the ball valve more than three, ring-type valve seat and ring-type valve bonnet with axial hole identical with the ball valve number are formed, in line check valve is installed between pump barrel assembly and the hollow shaft assembly, and fuel-displaced one-way valve assembly is installed between plunger piston assembly and the hollow shaft assembly.
Hollow oil pump pump oil production technology is: (1) annular pass between hollow shaft assembly and pump barrel assembly and plunger piston assembly promotes the crude oil of depths oil reservoir earthward; (2) inject chemical agent that dilutes viscous crude or the high temperature fluid of eliminating wax deposition, dead oil through hollow shaft assembly central through bore; (3) transfer the reservoir parameter test instrument through hollow shaft assembly central through bore, directly obtain reservoir parameter through transmission line.
Because the plunger piston assembly of hollow oil well pump has the central through bore of the upper and lower perforation that the hollow shaft assembly is installed, the hollow shaft assembly has the center trace hole of upper and lower perforation and structure and the oil production technology of being made up of ball valve, ring-type valve seat and ring-type valve bonnet of the present invention into and out of oily one-way valve, not only improved the testing precision of reservoir parameter, and high temperature fluid and chemical agent have been saved, improved and removed the efficient of wax deposition, dead oil and dilution viscous crude, thereby reached the object of the invention.
