Daim ntawv thov ntawm geophysical txiav nkhaus


Kev Ntsuas Hluav Taws Xob

Tsis

Nkhaus nta

Thov

Qhov cuam tshuam

Cov xwm txheej

Gradient electrode system txiav cov khoom siv

Thaj resistivity

1. Daim kab hauv qab muaj qhov siab tshaj plaws ntawm qhov qis kawg ntawm txheej txheej siab tshaj qhov siab thiab qhov tsawg kawg nkaus tus nqi rau saum.

2. Sab saum toj kawg nkaus muaj qhov siab tshaj plaws ntawm qhov kawg ntawm qhov siab cov txheej tiv thaiv thiab qhov tsawg kawg yog tus nqi rau hauv qab.

1. Txiav txim siab qhov tawm tsam ntawm qhov stratum.

 

2. Txiav txim siab lithology raws stratum resistivity.

 

3. Txheej txheej

1. Qhov txheej no thaiv cov nyhuv.

 

2.High-resistance nyob ze txheej txheej thaiv cov nyhuv

1.Txiav pem teb slurry

2.Oil av raws av nkos

3.Salty cement slurry

4. Tsis siv rau hauv cov qhov dej

Tej zaum cov tshuab hluav taws xob tsis zoo

Thaj resistivity

Qhov nkhaus yog qhov zoo sib xyaw nrog qhov nruab nrab ntawm qhov tsim, nrog siab muaj nuj nqis ntawm txheej txheej siab-siab, tsis tshua pom qhov tseem ceeb ntawm txheej txheej qis-qis, thiab lub pob zeb interface ntawm ib nrab-taw tes ntawm nkhaus.

1. Txiav txim siab qhov tawm tsam ntawm qhov stratum.

  

2. Txiav txim siab lithology raws li stratum resistivity

 

3. Txheej nrog ib nrab dav

Tsawg cuam tshuam

1.Txiav pem teb slurry

 

2. Tsis siv rau qhov tshij uas tau xeb

Microelectrode txiav ntoo

Resistivity ntawm ob qhov sib txawv hauv qhov dej

1. Qhov nkhaus ntawm lub siab tsis kam txheej muaj tus nqi siab, thiab cov nkhaus rau ntawm qhov muaj peev txheej tiv thaiv qis muaj tus nqi tsawg.

 

2. Muaj qhov sib txawv ntawm cov txheej osmotic, thiab tsis muaj qhov sib txawv ntawm cov txheej uas tsis ua rau ntev.

 

3. Qhov ib nrab-dav sib raug rau pob zeb tsim interface.

1. Txiav txim siab qhov permeability ntawm lub pob zeb stratum. Yog tias lwm cov xwm txheej zoo ib yam, qhov txawv yog loj thiab permeability tau zoo, txwv tsis pub nws yog me me.

 

2. Tshwj xeeb rau kev ua stratification.

 

3. Txheeb xyuas lithology, pom kev tiv thaiv zoo, thiab txhim kho kev tsim khoom.

1. Kev ua haujlwm tsis zoo yog hais txog qib ntawm cov khoom siv av ntawm cov av xuab zeb hauv kev tsim cov dej qab ntsev. Nyob rau hauv tib lub xuab zeb txheej, qib ntawm kev ua noj yog txawv ntau.

 

2. Qhov sib txawv ntawm qhov ntau ntawm ntu ntawm limestone yog qhov tsis tseeb.

 

3. Qee qhov av xuab zeb txho ua rau pom qhov tsis zoo uas tsis zoo nrog cov micro-gradients ntau dua micropotentials.

1.Txiav pem teb slurry

 

2. Tsis siv rau qhov tshij uas tau xeb
