Compared with prior art, the utility model has the beneficial effects that
First is that being changed according to oil well casing internal diameter, the amplitude for wiper block its spreading that centralizer body is equipped with is different, from
And ensure that guide shoe dipper is in well wellbore center always, it is easy fishing and arrives trouble of lost tool in hole；Second is that guide shoe dipper designs
The roofbolt of pit shaft bias internal is captured horn mouth by rotary guide shoe dipper by the bell mouth shape for angle shape with guide shoe function
Interior, the tooth form that inside is equipped with cone mouth shape saw type teeth is identical as the tooth form of oil well oil-pumping roofbolt for crude oil suction, taper
Be it is down big up small, can satisfy the well sucker rod of 22mm to 28mm plurality of specifications.Meanwhile saw type teeth also have the function of thread making.
Third is that returning its effect of water hole of returning that connector waterborne (3) is equipped with is that the sundries on trouble of lost tool in hole top is returned to pit shaft through returning water hole
It is interior, to ensure that salvaging one-time success rate.Labor intensity is alleviated, workover cost, promotional value with higher are reduced.
