Abstract
The present invention provides a kind of deviational survey sucker rod.The present invention includes one group of oil pumping bar body linked together by friction prevention device, it is characterized in that：Described friction prevention device is included positioned at the linkage section at two ends and positioned at middle abrasionproof section, anti-abrasion body is connected with by stopping means in described abrasionproof section, the oil-through hole axially in parallel with it is provided with described abrasionproof section, the two ends of described abrasionproof section are located at its outside and are respectively arranged with pressure sensor.Inclined situation can be transferred to control centre by the present invention in time after can working as sucker rod run-off the straight, and sucker rod is safeguarded in time, it is to avoid a greater degree of abrasion is caused to oil pick-up tube, extends the service life of oil pick-up tube.
Description
Technical field：
The present invention relates to a kind of deviational survey sucker rod, belong to technical field of petroleum machinery.
Background technology：
Oil pumper used in oil extraction in oil field is that, by a kind of up and down motion for laying particular stress on leverage (being commonly called as horse head machine), drive is taken out mostly
Beam hanger is moved back and forth, and completes Pumping action.Sucker rod is formed by the threaded connection of multistage bar, and sucker rod is curved in oil recovery process
Bent and cause the pressure friction with oil pipe to be inevitable due to bending, the solution generally used is on sucker rod
Several friction prevention devices (centralizer) are installed, friction prevention device is made of the material less than sucker rod, oil pipe hardness, external diameter and the oil of friction prevention device
There is less gap in pore footpath, thus, and friction prevention device can both play the centralizing function to sucker rod, can protect or reduce again oil pumping
The abrasion of bar.At present, wearing layer is mainly directly sleeved in sucker rod anti-abrasion device main body by used sucker rod anti-abrasion device
Portion.The sucker rod anti-abrasion device of this structure when in use, is primarily present problems with：In oil pumping process, when sucker rod inclines
After tiltedly, tilt data can not be transferred to control centre by existing sucker rod in time, it is impossible to safeguarded in time, caused sucker rod to incline
Tiltedly the abrasion to oil pick-up tube is increased.
The content of the invention：
The purpose of the present invention is to provide a kind of deviational survey sucker rod, the energy after sucker rod run-off the straight for above-mentioned problem
It is enough that inclined situation is transferred to control centre in time, sucker rod is safeguarded in time, it is to avoid more great Cheng is caused to oil pick-up tube
The abrasion of degree, extends the service life of oil pick-up tube.
Above-mentioned purpose is realized by following technical scheme：
Deviational survey sucker rod, including one group of oil pumping bar body linked together by friction prevention device, described friction prevention device include being located at
Anti-abrasion body is connected with by stopping means in the linkage section at two ends and the abrasionproof section positioned at centre, described abrasionproof section, it is described
The oil-through hole axially in parallel with it is provided with abrasionproof section, the two ends of described abrasionproof section are located at its outside and are respectively arranged with pressure
Sensor.
Described deviational survey sucker rod, described pressure sensor is arranged on abrasionproof by being embedded in the compression spring of abrasionproof section
Duan Shang.
Described deviational survey sucker rod, described stopping means uses stop nut or spacing clip.
Described deviational survey sucker rod, the described linkage section positioned at two ends, wherein one section has and is connected with oil pumping bar body
Internal thread, another section has and the external screw thread that is connected of oil pumping bar body.
Described deviational survey sucker rod, described anti-abrasion body is torus wearing layer.
Beneficial effect：
1. the present invention is linked together sectional sucker rod by friction prevention device, and each friction prevention device is provided at both ends with
Pressure data between corresponding site and oil pick-up tube is transferred to control centre by pressure sensor, pressure sensor, if each
The pressure of friction prevention device is uniform, illustrates that sucker rod is not tilted, if pressure differential, beyond the scope typically allowed, is said away from larger
Bright sucker rod, which is tilted, seriously needs finishing, is easy to timely safeguard of pinpointing the problems in time, it is to avoid larger abrasion is caused to oil pick-up tube.
2. the wearing layer of the present invention is fixed using stopping means, the axial float of wearing layer, the course of work effectively prevent
It is more reliable and more stable.

Embodiment：
Embodiment 1：
As shown in Figure 1：The deviational survey sucker rod of the present embodiment, including one group of oil pumping bar body 1 linked together by friction prevention device,
Described friction prevention device includes passing through spacing dress positioned at the linkage section 2 at two ends and in middle abrasionproof section 3, described abrasionproof section
Put 4 and be connected with anti-abrasion body, be provided with the oil-through hole 5 axially in parallel with it in described abrasionproof section, the two ends of described abrasionproof section
Pressure sensor 6 is respectively arranged with positioned at its outside.The present invention is linked together sectional sucker rod by friction prevention device,
And each friction prevention device is provided at both ends with pressure sensor, pressure sensor is by the number pressure between corresponding site and oil pick-up tube
According to being transferred to control centre, if the pressure of each friction prevention device is uniform, illustrate that sucker rod is not tilted, if pressure differential away from compared with
Greatly, beyond the scope typically allowed, illustrating that sucker rod is tilted seriously needs finishing, is easy to timely maintenance of pinpointing the problems in time,
Avoid causing oil pick-up tube larger abrasion.
Deviational survey sucker rod described in the present embodiment, described pressure sensor is by being embedded in the compression spring of abrasionproof section
7 are arranged in abrasionproof section.
Deviational survey sucker rod described in the present embodiment, described stopping means uses stop nut or spacing clip.
Deviational survey sucker rod described in the present embodiment, the described linkage section positioned at two ends, wherein one section has and oil pumping
The internal thread of bar body connection, another section has the external screw thread being connected with oil pumping bar body.
Deviational survey sucker rod described in the present embodiment, described anti-abrasion body is torus wearing layer.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned technological means, in addition to
The technical scheme being made up of above technical characteristic equivalent substitution.The unaccomplished matter of the present invention, belongs to those skilled in the art's
Common knowledge.
