4), find after overflow, should the closing well of termination of pumping in time.Before borehole pressure balance, formation gas still can constantly enter in well.Therefore, suppose to stablize from termination of pumping closing well to closing well during this period of time, in well, form one section of pure gas column of continuous print; And in Well Killing Process, this continuous gas column is not destroyed.

5), gas enters pit shaft and meets Darcy's law from stratum.

6) if the overflow entered in well is gas, then will expand when supposing that gas overflow rises in annular space, its expansion process meets the equation of gas state, and ignores gas slippage phenomenon.

7), the underground temperature gradient supposed in well is a constant, then:

Bottom temperature=underground temperature gradient × well depth+wellhead temperature.

(j ₁, j ₂, j ₃nozzle diameter, centimetre)

(2) overflow model

1), flooding process simulation

When there is overflow, the gas flow entered from stratum in pit shaft increases, and bottomhole wellbore pressure will constantly reduce, and gas admission velocity will constantly increase, and in this process, the change of all parameters is all the continuous function of time.For this reason, if in a quite little time interval Δ t, air inflow meets quadratic linear equation.

(1) gas flow calculates

Q_{gS} = C (P_{P}^{2} - P_{b}^{2})

In formula:

Q _gs--corresponding to P _bstandard state under gas flow amount, m3/s

P _p, P _b--stratum, shaft bottom effective pressure, kPa

A _a--this overflow segment annular space cross-sectional area, millimeter 2

--natural-gas integration amount in potpourri,

ρ _g--natural gas density, grams per cubic centimter

Because ρ _gmuch smaller than ρ, so above formula can be rewritten as:

2), closing well flooding process simulation

Closing well process is actually the process that bottomhole wellbore pressure recovers.During firm closing well, due to bottomhole wellbore pressure lack of equilibrium reservoir pressure, resident fluid also will continue to enter pit shaft, and the gases at high pressure entered, the compression of mineshaft annulus potpourri, make casing pressure and standpipe pressure constantly increase.Along with the prolongation of shut-in time, bottomhole wellbore pressure increases gradually, and resident fluid admission velocity reduces gradually, to the last bottomhole wellbore pressure equilibrium strata pressure.In closing well process, no matter be pit shaft or stratum, all parameters are all the functions of time.Because the mathematical model and computing method thereof that describe this process are very complicated, be not described further at this.Only provide the relevant parameters computing formula such as closing well stable rear shaft bottom potpourri length below.

(1) closing well stable rear shaft bottom potpourri length

H_{\min x ()} = [nΔP + Σ_{j = 1}^{n} U_{j} \frac{Q_{gs (j)}}{Q} \ln \frac{P_{P} - (n - j) ΔP}{P_{P} - (n - j + 1) ΔP}] / gρ

In formula:

ΔP＝gρQΔt/A _a

In n--annular space divide the hop count of potpourri

(2) closing well stablizes the length of the pure gas column in rear shaft bottom

H _mix(n+1)＝H _mix()-H _mix(n)

(3) gas expansion model

1), the equation of gas state

\frac{PV}{ZT} = \frac{P_{s} V_{s}}{Z_{s} T_{s}}

In formula:

P _s--the pressure under standard state, kPa

V _s--the volume under standard state, rice 3

Z _s--the compressibility coefficient under standard state

T _s--the temperature under standard state, ° K

P--pressure, kPa

V--gas volume, rice 3

T--temperature, ° K

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

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

2), the pressure 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:

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

In formula: ρ _s, P _s, T _s, Z _s--represent the gas density under standard state respectively, pressure, temperature and compressibility coefficient, T _x--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) represents, 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), gas compressive coefficient

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 it is more difficult for being expressed by compressibility coefficient by an accurate expression formula, can obtain compressibility coefficient with trial and error procedure, 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.
