Description
Technical field
The present invention relates to well recovery wellhead assembly technical field, more particularly, to a kind of thick oil production measuring well head device.
Background technology
Viscous crude, as the term suggests, it is a kind of sticky oil of comparison；Because its viscosity is high, density is big, is abroad typically referred to asHeavy oil, we are referred to as viscous crude at custom, and this names with respect to thin oil；Viscous crude and the contrast directly perceived of thin oil, we can see
Flow as water to thin oil, and viscous crude is difficult to flowing, this is that viscosity of thickened oil height causes, and some viscosity of thickened oil are up to hundreds of
Ten thousand mpas, as " black mud ", available spade, be held by hand, said with the language of science it is simply that the mobility of viscous crude too
Poor, so sticky oil, is difficult to naturally from underground extraction.
At present, in heavy oil wells exploitation, wellhead assembly is all using single rotatable shaft mouth test apparatus, though single rotatable test device
So to test instrunment using more convenient, but, due to the characteristic of viscous crude, it is easier oil pipe occurs at wellhead assembly to block up
Plug phenomenon；Through retrieval, application number：200420030450.7；Publication number：2687333；Denomination of invention：A kind of heavy oil production test
Wellhead assembly；Disclose a kind of thick oil production measuring well head device, viscous crude, in test process, because of hole deviation, the reason such as bending, makes
Oil pipe produces bending in well, at present, due to testing well use fixed or single rotatable wellhead assembly exist test inconvenience with
And the drawback such as poorly sealed, have impact on test and carry out, the present invention adopts in tubing hanger equipped with upper and lower for overcoming this shortcoming
Eccentric bushing, and the structure such as plane ball axle is it is achieved that oil pipe rotation and eccentric tubing string rotate so as to instrument connection can be around in sleeve pipe
The heart rotates, and reaches and prevents from testing the purpose in well endogenous cause of ill coiled tubing or resistance, card for the rope；The rotatable oil pipe of people is thus prevent oil
Pipe blocks in oil pumping, but increased labour cost simultaneously, wastes natural resources.
