b) Use of the HZGB127/89 Rubber-put drill pipe ektexine sludge
scraper
HZGB127/89 Rubber-put drill pipe ektexine sludge scraper is a kind
of equipment which can scrape off the mud affixing in the drill
pipe ektexine.It mainly used for petroleum and gas drilling
process,scraping off the drilling fluid affixing in the drill pipe
ektexine,reducing the lose of the drilling fluid as well as
pollution to the environment.
It can also replace artificial scraping so as to reduce the labor
intensity of workers. The drill pipe ektexine will be very clean
due to the use of the sludge scraper. When lifting drill you will
never see the work scenes drilling fluid everywhere on the surface
of the drill floor,dirty, slippery and dangerous.
c) Structure of the HZGB127/89 Rubber-put drill pipe ektexine sludge
scraper
Construction principle of the HZGB127/89 Rubber-put
drill pipe ektexine sludge scraper as shown
HZGB127/89 Rubber-put drill pipe ektexine sludge scraper is mainly
made up of sludge scraper underplate、pressure pad、inside hexagonal
nut、spring steel and crapper ring.The crapper ring is vulcanized by
the NBR mould, hollow in the middle, there will be contraction
allowance and flexible when drill rod coupling
passing,keeping the crapper ring affixing in the drill pipe
ektexine. Spring sheet steel lies in the middle of the crapper ring
so as to when axial direction stressed the crapper ring can also be
elastic and can scrape mud close to the drill pipe ektexine.
HZGB127/89 Rubber-put drill pipe ektexine sludge
scraper is of compact structure, modeling novel, it is convenient
for installation, using and maintenance in the field location.
d) Working principle of the HZGB127/89 Rubber-put drill pipe ektexine
sludge scraper
e)HZGB127/89 Rubber-put drill pipe ektexine sludge scraper mainly
put the hollow, flexible and wear-resistant NBR ring affixing in
the drill pipe ektexine closely,scrape off the drilling fluid
affixing in the drill pipe ektexine.When the drill rod lifting, the
crapper ring affixing in the drill pipe ektexine all the
time,scraping off the drilling fluid affixing in the drill pipe
ektexine.
When the drill rod lifing to the coupling,as the maximum elongation
of the NBR ring greater than or equal to 400%, the coupling will
extend the crapper ring aperture and pass the crapper ring.After
passing the crapper ring,due to the NBR ring with good flexibility
and affixing in the drill pipe ektexine closely, scrape off the
drilling fluid affixing in the drill pipe ektexine,leading the
drill pipe ektexine clean , no pollution and drilling workers have
a good working environment.

g) Installation and use of the HZGB127/89 Rubber-put drill pipe
ektexine sludge scraper
1 After taking off the square Kelly when lifting,cover the sludge
scraper to the drill rod in the the mouth of a well.(You'd better
put a taper joint join to the drill rod, convenient for drill pipe
ektexine sludge scraper cover in the drill.
2 Use lift sub lift the drilling tool in the well, raking-out the
turntable quadrel.
3 Puse down the HZGB127/89 Rubber-put drill pipe ektexine sludge
scraper above to the mouth of a well as well as pipe socketbelow to
the turntable quadrel.
4 Hang the turntable quadrel back to the turntable quadrel
hole,and lock the lockpin of the turntable quadrel.
5 Under the turntable quadrel of sludge scraper stabbing sludge
when the
drilling rod lifting, sludge ring can scraper clean the drill rod
ektexine
drilling fluid.
6 Drilling fluid scraped flow to the mouth of a well as well as
pipe socket and back to the well .
7 After lifting, get out the the turntable quadrel,take out the
drill pipe ektexine sludge scraper from the well,clean it in the
clean water and use it next time.
h)、Maintenance and repair of the HZGB127/89 Rubber-put drill pipe
ektexine sludge scraper
1 Clean the sludge scraper in the clean water after using,keep
it in the shade.
2 After outwear,you can replace a new crapper ring.
3 When replacing the crapper ring,yo
