Z--is T in temperature, and pressure is the compressibility coefficient under the condition of P

As long as be aware of the pressure in certain moment, temperature and compressibility coefficient, just can in the hope of gas volume now.

2), the pressure model that produces in annular space of gas overflow weight

According to gas in annular space in uphill process gas weight constant, trying to achieve gas column with the equation of gas state in the density in kill-job moment is:

In formula: ρ _s, P _s, T _s, Z _s--represent the gas density under standard state respectively, pressure, temperature and compressibility coefficient, T _s--gas rises to a certain moment gas column mid point formation temperature, ° K

The pressure that then gas column weight causes is:

P_{w} = 9.8 ρ_{g} H_{x} = \frac{9.8 P_{x} Z_{s} T_{s} ρ_{s}}{Z_{x} T_{x} P_{s}}

By gas height gas volume V _x(rice ³) and cross-sectional area A _a(rice ³) represent, then:

P_{w} = 9.8 \frac{P_{x} Z_{s} T_{s} ρ_{s} V_{x}}{P_{s} Z_{x} T_{x} A_{a}}

A in formula _afor the cross-sectional area of gas place annular space section, change; But in order to convenience of calculation, can by A _avalue be taken as the average traversal area of whole annular space, then the pressure that gas weight causes is a constant.Because the value of this pressure is originally very little, the error caused after such simplify processes can be disregarded.

3), natural gas compressing model

Quote Kenneth, the formula that R.Hall proposes, after simplifying, obtains following computing formula to ask Z _xvalue:

Z = 1 + (0.3156 - \frac{1.0467}{T_{r}} - \frac{0.5783}{T_{r}^{3}}) W + (0.5353 - \frac{0.6123}{T_{r}}) W^{2} + W^{2} \frac{0.6815}{T_{r}^{3}}

In formula:

W = 0.27 \frac{P_{r}}{{ZT}_{r}}

Reduced pressure

P_{r} = \frac{P}{49.9 - 3.7 ρ_{g}}

Reduced temperature

T_{r} = \frac{T}{49.9 - 3.7 ρ_{g}}

Above formula is an implicit form, and its solution is: first suppose an initial compression factor Z ₀, calculate P _r, T _r, then obtain W, finally calculate Z again, if | Z-Z ₀|≤ε (ε is precision, generally gets 0.0001), then illustrate the Z of hypothesis ₀it is exactly required compressibility factor; If | Z-Z ₀| > ε, then illustrate and need again to suppose Z ₀, then calculate Z.Until | Z-Z ₀| till≤ε meets.
