Dissolvable Frac Plug Cov ntaub ntawv

Hydraulic fracturing yog cov txheej txheem siv dav hauv kev lag luam roj thiab roj los txhim kho kev tsim cov hydrocarbons los ntawm cov dej qis permeability. Thaum lub sij hawm tus txheej txheem no, frac plugs yog ua hauj lwm los cais ib cheeb tsam nyob rau hauv lub wellbore, tso cai rau staged fracturing ua hauj lwm. Kev lig kev cai, cov frac plugs no tau muab rov qab los ntawm mechanically, ntxiv complexity thiab nqi rau kev ua haujlwm. Txawm li cas los xij, kev taw qhia ntawmdissolvable frac plugs revolutionized kev lag luam los ntawm muab ib tug ntau npaum thiab nqi-zoo lwm txoj.

Dissolvable choj plugs yog tsim los ntawm ntau yam ntaub ntawv tsim los yaj los yog degrade nyob rau hauv tshwj xeeb downhole tej yam kev mob, tshem tawm qhov yuav tsum tau rau mechanical retrieval. Plaub pawg loj tuaj yeem siv los pab pawg cov ntaub ntawv no:

Cov khoom siv raws li ntsev (xws li cov poov tshuaj thiab sodium chlorides): Cov tshuaj no feem ntau siv rau hauv cov ntawv thov kub thiab soluble hauv cov kua dej. Lawv muab tus nqi qis dua thiab nrawm nrawm.

Cov khoom siv raws li cov carbonates, xws li calcium carbonate, yaj hauv cov kua qaub, ua rau lawv muaj txiaj ntsig zoo hauv kev siv nrog hydrochloric acid lossis lwm yam kev kho acidizing. Lawv muab cov kev sib cais nruab nrab thiab sib haum nrog ntau yam kev mob zoo.

◆ Cov khoom siv organic: Cov no yog los ntawm cov khoom siv ntuj tsim thiab feem ntau yog biodegradable (xws li cellulose, starch). Lawv tuaj yeem tsim los ua kom yaj hauv cov kua dej tshwj xeeb lossis degrade thaum lub sijhawm vim muaj cov kab mob los yog kev ua haujlwm enzymatic. Organic cov ntaub ntawv muaj ntau yam kev sib cais tus nqi thiab yog ib puag ncig tus phooj ywg.

◆ Cov khoom siv hlau (xws li magnesium alloys): Cov ntaub ntawv no yog tsim los ua kom yaj los ntawm cov tshuaj electrochemical hauv cov cheeb tsam aqueous. Vim tias lawv lub zog-rau-qhov hnyav piv thiab tswj cov kev sib cais, magnesium alloys tau siv ntau heev. Lawv tsim nyog rau ntau yam kev mob zoo thiab tuaj yeem muab cov cuab yeej zoo.

Kev xaiv ntawm qhov tsim nyogdissolvable frac plugcov khoom siv yog qhov tseem ceeb rau kev ua tiav kev tawg. Ntau yam tseem ceeb yuav tsum tau xav txog:

◆ Dissolution tus nqi thiab solubility nyob rau hauv cov kua sib txawv (xws li dej, acid, hydrocarbons): tus nqi dissolution yuav tsum tau raws li cov kev cai ntawm lub qhov dej thiab fracturing kua siv. Cov ntaub ntawv uas muaj solubility siab nyob rau hauv cov dej xav tau yog qhov zoo dua rau kev so kom zoo thiab tshem tawm.

◆ Lub zog ntawm lub zog thiab kev tiv thaiv kev yaig: Cov txuas txuas txuas txuas txuas tsis tau yuav tsum tiv taus qhov sib txawv siab thiab erosive rog thaum ua haujlwm tawg. Cov ntaub ntawv uas muaj zog txhua yam muaj zog thiab yaig tsis kam yog xav tau kom muaj kev ruaj ntseg zoo.

◆ Kub stability thiab tsis kam mus degradation: downhole kub yuav txawv heev, thiab cov ntaub ntawv dissolvable yuav tsum tswj lawv cov qauv kev ncaj ncees thiab dissolution zog tshaj qhov xav tau kub ntau yam.

◆ Cov xwm txheej zoo: Kub, siab, thiab cov kua dej muaj pes tsawg leeg ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom tsim nyog. Piv txwv li, cov qhov dej kub kub yuav xav tau cov ntaub ntawv nrog kev txhim kho thermal stability, thaum acidic ib puag ncig yuav tsum tau siv cov khoom siv acid-soluble.

◆ Fracturing fluid compatibility: Cov khoom siv dissolvable yuav tsum tau sib xws nrog cov kua fracturing siv, kom ntseeg tau tias muaj txiaj ntsig zoo thiab tshem tawm yam tsis muaj kev cuam tshuam rau kev ua haujlwm tawg.

◆ Cov kev xav tau ntawm kev ua haujlwm: Qhov xav tau kev sib cais, lub zog ntawm lub zog, thiab kev xav txog ib puag ncig yuav tsum raug muab xam rau hauv cov txheej txheem xaiv cov khoom.

Txoj kev tsim khoom ntawmdissolvable frac plugskoom nrog cov txheej txheem tshwj xeeb los xyuas kom meej qhov zoo thiab kev ua tau zoo. Nyob ntawm cov khoom siv, ntau txoj hauv kev xws li hmoov metallurgy, kev txhaj tshuaj molding, lossis extrusion tuaj yeem ua haujlwm.

Kev soj ntsuam nruj thiab kev ntsuas kev tswj xyuas zoo yog qhov tseem ceeb los xyuas kom meej cov khoom xav tau ntawm cov khoom tawg. Kev ntsuam xyuas yog ua los soj ntsuam cov nqi tawg, lub zog siv tshuab, thiab kev sib raug zoo nrog cov kua dej zoo nyob rau hauv simulated downhole tej yam kev mob. Cov kev sim hauv teb chaws thiab cov ntaub ntawv zoo tiag tiag muab kev pom zoo rau kev ua haujlwm ntawmdissolvable frac plugsnyob rau hauv lub ntiaj teb no scenarios.
