What is mlst
What is MLST

  • Using double-sealed plug to well screen segments separated to flow only from the test section and out, let air into the connecting pipe, causing the water level surface of the tube down a steady rate.

  • When release the gas, tube between inside and outside the pressure difference cause the groundwater level surface pressure changes .


Flow field geometry of n
Flow Field Geometry of n

planar, n=1

radial, n=2

spherical, n=3

n=1

1<n<3

n=2






Skin effect
Skin Effect

  • In the drilling process, Caused by human factors as changes in the wellbore permeabilitiy.

  • If the permeability in the skin zone

    (1)less than that in the rest of the formation , Skwillbe positive.

    (2) equal ,Sk=0.

    (3)greater than that in the rest of the formation ,Skwill be negative.




Conclusion
Conclusion

Effect hydraulic conductivity of the factors

(1)Flow dimension.

(2)Fully penetrating slug test or partially penetration slug test.

(3)Skin effect.

Cause several combinations, the formation of a non-unique.


Future work
Future Work

  • Improve the understanding the Parameters of

    Flow area、Skin effect and etc .

  • Adding observation well field data.
