Dissolvable bridge plug inogadzirwa nezvinhu zvitsva, iyo inoshandiswa seyenguva pfupi tsime rekuvharisa segmentation chishandiso cheyakatwasuka tsime rekutsemuka uye kugadzirisa.
Dissolvable bhiriji plug inonyanya kuumbwa nezvikamu zvitatu: bhiriji plug muviri, anchoring michina uye zvisimbiso. Iyo bhiriji plug muviri wakagadzirwa neakakwira-simba rinonyungudika zvinhu, kusanganisira yepakati chubhu, koni, mhete yekudzivirira uye majoini. Iyo anchoring mechanic inogadzirwa nezvinhu zvinonyungudika semutakuri, uye pamusoro inobatwa nealloy poda, alloy particles kana ceramic particles. Zvisimbiso zvinobviswa rabha kana plastiki.

Dissolvable bhiriji plugs anonyanya kugadzirwa neakakwirira-simba magnesium-aluminium alloy kana polymer zvinhu kugadzirisa. Magnesium-aluminium alloy inonyanya kuumbwa ne magnesium, ine density yakaderera (inenge 1.8 ~ 2.0g / cm³), uye panguva imwechete, basa rayo remakemikari rakakwirira, saka zviri nyore kunyungudutswa munzvimbo ine hunyoro.
Kuparara kwehuwandu hwe magnesium-aluminium alloy inonyanya kuenderana nekushisa kwemvura uye Cl-concentration, iyo yakakwirira tembiricha, inokurumidza kupera; iyo yakakwirira yeCl-concentration, iyo inokurumidza passivation firimu pane alloy surface inoparadza, zviri nani conductivity yemvura, inokurumidza kupera kwehuwandu.
2.Dissovable bhiriji plug anchoring mechanism
Dissovable bhiriji plug anchoring tile yakasiyana kubva kune yakajairwa simbi simbi tile uye composite tile, mukuwedzera kune iyo inodiwa yekupa yakavimbika casing anchoring simba uye silinda yekuvhara simba, asi zvakare inofanirwa kuve nekuita kwakanaka kwekunyungudika uye kugona kudzoka pakuburitsa.
3.Dissolvable Bridge Plug Seat Seal Release Value
Baker 20 # hydraulic seating tool ichave yakabviswa bhiriji plug yakagara mucasing tooling, maitiro ekuyedza bhurogi plug nechigaro chekugara chakanyatsoenderana, plug yebhiriji yakagara zvakanaka uye yakarasika ruoko, kurasikirwa kwekumanikidza kweruoko kwe12.3MPa. (yakaenzana kurasikirwa kwesimba remaoko rinosvika 155kN) akagara ruoko curve sezvakaratidzwa mumufananidzo.
4.Pressure sealing performance ye dissovable bridge plug
Kuti zvionekwe kusimba kwekuvharisa kwepamusoro-tembiricha yekuvharisa plug yebhiriji, mugadziri wekesi akaiswa mumudziyo wekuyedza wepamusoro-soro uye akadziya kusvika 93°C. Mushure mekunge tembiricha yakagadzikana, kudzvanywa kwakawedzera zvishoma nezvishoma kusvika 70 MPa. Dzvinyiriro yacho yakatsiga kwemaawa makumi maviri nemana ndokuzochengetwa kwemaminitsi gumi nemashanu. Pane kudonha kuri pachena kwekumanikidza uye iyo yekumanikidza test curve inoratidzwa mumufananidzo. Mhedzisiro yemuyedzo inoratidza kuti kudzvanywa kwekuvhara kuita kwebhiriji plug kunogona kusangana nezvinodiwa zvepa-saiti fracturing kuvaka.
5.Kushanda nguva ye dissovable bhiriji plug
Muganho wenguva yekushanda inguva kubva painopinzwa plug yebhiriji mutsime kusvika pakutsemuka. Zvinoenderana neiyo iripo shale gasi yekuvaka modhi, iyo nguva yekushanda yeinoparara bhiriji plug imaawa makumi maviri nemana, iyo inogona kuzadzisa zvinodiwa pa-saiti yekuvakwa kwematsime egasi e shale, ndiko kuti, kubva panguva yekuiswa kwebhurogi rinoputika. mutsime Kutanga kubva paawa, fracturing kuvaka inogona kuitwa mukati memaawa makumi maviri nemana. Chero bvunzo dzekuita kweanogona dissvavable bhiriji plugs inogona kuitwa nekutarisa kune 24-awa yekushanda nguva yakatarwa.
