1.Pipe pullback
Matanho ekudzivirira kukundikana kwe pullback:
(1) Ita ongororo yekuona yezvishandiso zvese zvekuchera usati washanda, uye ita ongororo yekuona kukanganisa (Y-ray kana X-ray inspection, nezvimwewo) pamaturusi makuru ekuchera akadai sepombi dzekuchera, reamers, uye mabhokisi ekutamisa kuona kuti pane hapana kutsemuka uye simba rinosangana nezvinodiwa zvekuvaka.
(2) Iyo dhayamita yekupedzisira yekudzokororwa yakakura kudarika ka1.5 yepombi inodhonza kumashure. Kutevedzana kwepombi pullback: simba musoro - simba musoro kudzivirira zamu - drill pombi - reamer - swivel joint - U-shaped mhete - musoro wetirakita - mutsara mukuru, unokwanisa kuona kuti simba rakawanda rekuchera rinoshandiswa kune simba rekudhonza panguva yekudhonza shure uye kuve nechokwadi chekubudirira kwekudhonza. Kana uchimisa kuchera, chigadziro chekuchera chinofanira kubatanidzwa nekukurumidza, uye nguva yekumira yekuchera. chishandiso mugomba rekutyaira chinofanira kupfupikiswa zvakanyanya sezvinobvira, uye hachifanirwe kudarika maawa mana.Kana dzikamira, madhaka anopinzwa mugomba nguva nenguva kuitira kuchengetedza kuyerera kwedhaka mugomba.
(3) Pombi isati yadzoserwa kumashure, chidhiraivho, mudziyo wekuchera, dhaka rinotsigira system uye zvimwe zvekushandisa zvinofanirwa kuongororwa uye kuchengetedzwa zvakakwana (pamwe nemarekodhi ekuchengetedza uye ekugadzirisa akabatanidzwa) kuve nechokwadi chekuti chidhiraivho nehurongwa hwayo hwemagetsi zvine basa rakanaka. uye kushanda zvakajairika.Geza pombi yekuchera nedhaka usati wadhonzera kumashure kuti uone kuti hapana chinhu chekunze mupombi yekuchera;Iyo madhaka system inotsvedza uye kudzvanywa kunogona kusangana nezvinodiwa zvekudhonza.Munguva yekudhonza, ita bvunzo yekupfapfaidza kuona kuti muromo wemvura hauna kuvharika.Panguva yekudhonza, bayai madhaka akakodzera zvichienderana nemadhirowa, dzikisa kukweshera pakati pepombi yekuboorera nedombo remuburi regomba, wedzera mafuta epombi, dzikisa kupisa kwekukwenya kwepombi yekuboorera, uye simbisa budiriro yekudhonza kumashure.
Matanho ekuona kuti pombi yekudzivirira-corrosion coating haina kukuvara kana gomba rawedzerwa nekudhonzwa kumashure.
(1) Pakuboora gomba rekutyaira, ita kuvaka zvinoenderana nezvinodiwa nedhizaini kuti uone kuti gomba rekutyaira rakatsetseka uye rakati sandarara, uye dzivirira makona akawandisa.Paunenge uchikwevera kumashure, iyo dhayamita yeiyo reamer inoshandiswa inodarika 1.5 nguva yakakura kupfuura dhayamita yepombi yekuyambuka kuti kuderedze kudhonzera kupikisa uye kuderedza chiitiko chekukwenya pakati pepombi nemadziro egomba.
(2) Wedzera kugezeswa kwegomba kuti uchenese zvimwe zvakachekwa mugomba uye kuderedza kukweshera kwepombi mugomba.
(3) Chiyero chedhaka chinoshanduka nemamiriro e geological.Madhaka anorapwa panguva yekudhonzwa, uye imwe huwandu hwemafuta anowedzerwa kuderedza kupesana kwekupokana pakati pepombi nemadziro egomba.Iyo madhaka viscosity inofanirwa kugadziriswa chero nguva zvichienderana nemamiriro chaiwo.Zvinoenderana nekuchinja kwe geological, iyo yedhaka reshiyo viscosity uye kudzvanywa kunogadziriswa chero nguva, uye chiyero chedhaka chinoshandiswa kumisa pombi mumatope panguva yekudhonza kumashure kuderedza kukwesha.
(4) Mushure mekunge kudzokororwa kwapera, tanga watarisa pombi yekudzosera kumashure.Mushure mekusimbisa kuti anti-corrosion layer yakamira uye hapana kukanganiswa kwevanhu, zvinoenderana nemamiriro enzvimbo, pombi inomiswa nekuchera kutumira migero uye mirwi yevhu kuchengetedza anti-corrosion layer yepombi..
(5) Kana pombi yadhonzerwa kumashure, misa nzvimbo yekuona yekudzivirira kukoromoka kwemamita makumi matatu pombi isati yapinda mugomba (kana zvinoenderana nemamiriro ezvinhu panzvimbo), uye ronga vashandi vakasarudzika kuti vachenese pamusoro peiyo anti- corrosion layer pamberi penzvimbo yekuona, kuitira kuti zvive nyore kune vashandi panzvimbo yekuona kuti vashandise EDM yekuona inoputika inotarisa kana pane zvikwangwani kana kuputika pane anti-corrosion layer, uye kugadzirisa kukanganisa munguva apo kukwenya uye kubuda kunowanikwa. , kuitira kuti usapinda mugomba.
2.The proportioning nzira, kupora uye
treatment zviyero zvedhaka
Kugadzirira kwevhu:
Chiyero chedhaka chinoita basa guru mukubudirira kwekuyambuka.Iyo viscosity yekugadziriswa kwedhaka reprojekiti ichave yakavakirwa padhizaini yekudhirowa uye geological prospecting data, maererano nekugoverwa kweakasiyana madhaka viscosity kune akasiyana strata, mukuita kwekuchera makomba maburi, inofanirwa kuve nechokwadi chezvakanaka rheological properties, lubrication performance;Munguva yekudzorerazve, dhaka viscosity ichagadziriswa zviri nani maererano neinotungamira rekodhi kuti ive nechokwadi chekuti dhaka rine yakasimba cuttings inotakura simba uye kudzivirira kwemadziro.Panguva imwecheteyo, mune imwe neimwe nhanho yekutungamira, kudzoreredza uye kudzosera kuvaka, zvichienderana neiyo chaiyo data, wedzera madziro ekusimbisa agent, viscosifier, lubricant, chip yekuchenesa agent uye mamwe anobatsira vamiririri, kuwedzera dhaka viscosity uye simende, kuwedzera kugadzikana kwe. gomba, kudzivirira gomba remadziro kudonha, slurry leakage uye zvimwe zviitiko, kuve nechokwadi chemhando yeprojekiti inopedzwa zvakanaka.Madhaka acho anonyanya kuve bentonite (yakanaka kwezvakatipoteredza), uye kugadzirwa kwematope kunoenderana nemamiriro evhu anotarisana nawo pakuchera.Kune iyi purojekiti kuburikidza nekuumbwa kukuru, kugadzirira kwedhaka kweiyo huru index.
Kupora uye kurapwa kwedhaka:
Kuti unyatso kudzora huwandu hwemadhaka, chengetedza nharaunda yezvakatipoteredza, sezvinobvira kushandisa matope ane ushamwari, kudzokorodza, muganhu wepamusoro kuderedza chizvarwa chemarara emarara, panguva imwe chete kudzivirira slurry kusvibiswa, kudzokorodza nenguva yekunze. kurapwa kwezvakatipoteredza, matanho chaiwo ndeaya anotevera:
(1) Tungamira madhaka anoshamwaridzana nenharaunda ari kudzoka kubva pasi achienda kune inotenderera sisitimu, uye kuburikidza nedhishi rinotenderera uye tangi yekuchera, iyo yekuchera inocherwa inonatswa kuti iwane yekutanga yekucheneswa maitiro.Mushure mekucheneswa kwekutanga, madhaka anoyerera achipinda mudziva revhu kuti amire.Kuti ikurumidze kunaya kwezvimedu, baffle inogadzika mudziva rematope kuti ichinje kuyerera kwayo uye kuparadza chimiro mumatope, kuitira kuti kunaya kwekucheka kwekucheka.
(2) Ronga vashandi vakasarudzika kuti vatarise mutsara, kusimbisa chiratidzo chekuongorora, uye kana paine slurry leakage point, rongai vashandi kuti vavake cofferdam panzvimbo iyo slurry iri kubuda kuti ivemo uye kuibvisa nekukurumidza, saka sekudzivirira slurry kubva pakupfachukira uye chiyero cheslurry kubva pakuwedzera.Inounganidzwa yobva yadhonzwa nerori rematangi kuenda kugomba remadhaka riri panzvimbo yekuvaka.
(3) Pashure pokunge kuvakwa kwapedzwa, madhaka ari mugomba revhu panzvimbo yokuvaka anoparadzaniswa namadhaka nemvura, uye marara asara anotakurwa kunze nokuda kwokuchengetedzwa kwezvakatipoteredza.
3. Special technical matanho
Drilling rig anchoring system:
Mukuita kwekuchera kwakananga, nekuda kwekusagadzikana kwechimiro chepasi pevhu, iyo yekuchera inobatwa zvakanyanya nekuita simba kwepombi yekubooresa mugomba panguva yekudzorera uye backhauling.Kuwedzera kamwe kamwe kwekunetsa kunogona kukonzera kusagadzikana kweiyo drilling rig uye kunyangwe tsaona yekudhiraivha inonongedza pamusoro.Nokudaro, kugadzikana kweanchoring system yekuchera rig inonyanya kukosha.Zvinoenderana neruzivo rweiyi purojekiti uye kuvakwa kwakapfuura, iyo anchoring system yekuchera rig yakagadziridzwa, kunyanya sezvinotevera:
(1) Isa chiremerera chepasi mugomba, uye mutsara wepakati webhokisi resimbi rinopindirana neakisi yekuyambuka.Pamusoro peiyo pasi anchor bhokisi inotsvedza nevhu remusikirwo, uye iyo yekuchera yepasi anchor bhokisi ndeye 6m×2m×2m.
(2) Iyo tubular muswe anchor inoiswa 6 metres kuseri kwebhokisi anchor bhokisi, uye pasi anchor bhokisi uye muswe anchor zvakabatanidzwa nekubatanidza tsvimbo.Mushure mekunge anchor yemuswe yabatanidzwa, nyika inodzoserwa kumashure, uye ivhu rakatenderedza anchor rinotsikirirwa nemakanika uye artificially.Wedzera simba rekubereka ivhu.
(3) Isa danda remamita matanhatu padivi rega rega rebhokisi resimbi kuti udzivise muviri mukuru kurereka.
(4) Isa 6 × 0.8m simbi pombi pamagumo epango kuti uwedzere nzvimbo yekunetseka kwese uye kuderedza kumanikidza.
(5) Mushure mekugadzwa, ndiro yesimbi inofanira kuiswa mu anchoring system, uye rig inofanira kuiswa pamusoro peplate yesimbi.
Iyo kambani Gookma Technology Industry Company Limitediri hi-tech bhizinesi uye inotungamira mugadziri wehorizontal directional drilling machinemuChina.
