n: The tool that goes in the hole with fishing tool. It can not fish by itself but is helpful for fishing operation.

a flux damage estimating system.

n: a geologic structure resembling an inverted bowl, i.e., a short anticline that dips or plunges on all sides.

a symmeatrical upfold of the layers of rock in which the beds dip in all directions more or less equally from a common point;any deformation characterized by a circular local uplift.

n: A common and inexpensive measurement of the natural emission of gamma rays by a formation. Gamma ray logs are particularly helpful because shales and sandstones typically have different gamma ray signatures that can be correlated readily between wells

gas production facility.

n: according to the testof hydrauic fracture and sand box,Hubbert and Willis propose firstly the theoric solution to estimate the pressure of formation fracture. The express is as follows: Pf =PP+(1/3~1/2)*(P0-Pp).

the measurement of a wells deviation from vertical. When used with fluids, a positive number indicates upflow and a negative number may represent downflow.

n: when shutting in after overflow, we uses the known data to caculate the density of overflow and identifies the sort of overflow , then it is helpful to well control.

n: the wireline attached to a mast or derrick to provide the main support for the structure. Compare wind guy line.

n: the crude oil or refining oil that uses in the acid fracture, it is helpful to increasing the prodution.

n: on the basis of huber -wellise method, lead in variable base rock stress factor Ki , the caculation model is as follow: Pf=P+Ki( p0-p）。
