Abstract
The invention discloses a brake anti-blocking screw drilling tool with long service life, comprising a well head double-stage filtering device, an upper brake anti-blocking device, a hydraulic motor assembly, a transmission shaft assembly and a lower brake anti-blocking device. The brake anti-blocking screw drilling tool has the advantages as follows: the double-stage filtering is adopted, therefore, the filtering is performed according to particle diameters of impurities, the impurities such as sand grains in different particle diameters can be effectively prevented from entering into the drilling tool through well liquid, the anti-blocking and anti-wearing effects are much better, the service life of the drilling tool is prolonged, the drilling tool is avoided being dismounted due to blocking and wearing, and the work efficiency is improved; when the well liquid passes through, a filter screen plays a role in filtering, and when a pump is stopped, a spring is returned and a valve core is closed so as to play a role in braking, therefore, the well liquid with sand grains can be prevented from flowing back into the drilling tool to cause the blocking of the drilling tool.
Description
Technical field
The present invention relates to a kind of drilling well, well workover power drilling tool.
Background technology
Petroleum resources are a kind of non-renewable resources, and along with the increasing of oil exploitation synergy control potentiality degree, to more deeply more complicated geological extension, inclined shaft, horizontal well and service shaft are more and more gradually for oil drilling, workover treatment; When the common screw drilling tool carried out drilling well, workover treatment in these complicated wells, circulation fluid had impurity such as sand grains, caused drilling tool to stop up easily; In addition, because strata pressure is higher, during the well head termination of pumping; Downhole fluid can pass through bit port and bypass valve spout hole backflow drilling tool, causes drilling tool to stop up, even through gushing raised platform around a well on drilling rod or the oil pipe; Cause drilling tool to damage and remove again, operating cost increases, and causes raised platform around a well to pollute.
Summary of the invention
Technical problem to be solved by this invention is: the anti-blocking helicoid hydraulic motor of non-return that a kind of long service life is provided.
In order to solve the problems of the technologies described above; The technical scheme that the present invention adopts is: the anti-blocking helicoid hydraulic motor of non-return; Comprise: the bipolar filter of well head, last non-return anti-block apparatus, hydraulic motor assembly, driving-shaft assembly and following non-return anti-block apparatus, the structure of the bipolar filter of said well head comprises: shell, setting one-level chimney filter and secondary chimney filter in the enclosure; The said structure that goes up the non-return anti-block apparatus comprises: go up shell, be arranged on last setscrew nut, upper valve sleeve, upper valve core and upper reset spring in the shell; The structure of said down non-return anti-block apparatus comprises: lower casing, be arranged on following setscrew nut, lower valve sleeve, bottom spool and following back-moving spring in the lower casing.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adopts is: on said, also be provided with filter screen in the shell.
In order to solve the problems of the technologies described above better, the further technical scheme that the present invention adopts is: the diameter of the one-level filter opening on the said one-level chimney filter is 3-4mm, and the diameter of the secondary filter opening of said secondary chimney filter is 1.8-2.5mm.
Advantage of the present invention is: the anti-blocking helicoid hydraulic motor of above-mentioned non-return, owing to adopt bipolar filtration, filter respectively by the impurity particle diameter, and prevent that effectively impurity such as different-grain diameter gravel from getting into drilling tool through well liquid; The anti-blocking wearing-resistant effect is better, has prolonged drilling tool application life, avoids having improved operating efficiency because of obstruction, wearing and tearing drilling; When well liquid passes through, the filter screen filtration, when termination of pumping, spring reset; Spool is closed, and plays the non-return effect, prevents to have the well liquid refluence drilling tool of sand grains, causes drilling tool to stop up.

The specific embodiment
Describe particular content of the present invention in detail below in conjunction with accompanying drawing and specific embodiment.
Like Fig. 1, shown in Figure 2; The anti-blocking helicoid hydraulic motor of non-return; Comprise: the bipolar filter of well head, go up non-return anti-block apparatus, hydraulic motor assembly 1, driving-shaft assembly 2 and following non-return anti-block apparatus, the structure of the bipolar filter of said well head comprises: shell 3, be arranged on shell 3 interior one-level chimney filter 4 and secondary chimney filter 5; The said structure that goes up the non-return anti-block apparatus comprises: go up shell 6, be arranged on last setscrew nut 7, upper valve sleeve 8, upper valve core 9 and upper reset spring 10 in the shell 6; The structure of said down non-return anti-block apparatus comprises: lower casing 11, be arranged on following setscrew nut 12, lower valve sleeve 13, bottom spool 14 and following back-moving spring 15 in the lower casing 11.
As shown in Figure 2, on said, also be provided with filter screen 16 in the shell 6.As shown in Figure 1, the diameter of the one-level filter opening 17 on the said one-level chimney filter 4 is 3-4mm, and the diameter of the secondary filter opening 18 of said secondary chimney filter 5 is 1.8-2.5mm.
When the anti-blocking helicoid hydraulic motor of above-mentioned non-return used, the top connection 19 of the bipolar filter of well head upper end was connected with the pond through water pipe, and the lower contact 20 of the bipolar filter of well head lower end is connected through the joint 21 of oil pipe with last non-return anti-block apparatus upper end.Well liquid filters through filter screen 16 after filtering through one-level chimney filter 4 and secondary chimney filter 5 again, owing to adopt bipolar filtration, filters respectively by the impurity particle diameter; Prevent that effectively impurity such as different-grain diameter gravel from getting into drilling tool through well liquid, the anti-blocking wearing-resistant effect is better, has prolonged drilling tool application life; Avoid because of obstruction, wearing and tearing drilling; Improved operating efficiency, when well liquid passed through, filter screen 16 was filtered once more.Well liquid is pushed upper valve core 9 open, gets into hydraulic motor assembly 1, drilling tool work.When quitting work, upper reset spring 10 resets, and upper valve core 9 is closed, and plays the non-return effect, and well liquid can not be up.Following non-return anti-block apparatus is positioned at power transmission shaft 22 lower ends, and drill bit connects with the lower ends of following non-return anti-block apparatus, and well liquid gets into non-return anti-block apparatus down through back in the driving-shaft assembly 2, pushes bottom spool 14 open; Get into drill bit, drilling tool work is when quitting work; Higher like bottom pressure, when well liquid passed through bit port backflow drilling tool, the following back-moving spring 15 of following non-return anti-block apparatus resetted; Promote bottom spool 14 up and lower valve sleeve 13 sealings, prevent to have the well liquid refluence drilling tool of sand grains, cause drilling tool to stop up.
