The paper presents a method for calculating the gas stream flow rate during well tests of gas and gas condensate wells using a diaphragm gauge of critical flow. The above method compensates the disadvantages of the described in the scientific and technical literature gas stream flow rate calculation methods during its flow through the diaphragm in the critical regime. For the proposed method are presented the testing results on gas and gas condensate wells of the north of the Tyumen region.

The review and analysis of the formula suggested in scientific technical literature for calculation of the compression ratio of gas stream passing through a diaphragm in the critical flow mode were conducted. The basic assumptions were formulated which lead to its incorrect determination and directly introduce the error in the calculation of the medium flow rate. The analytical solution id is suggested for obtaining a reliable value of the compression ratio of gas stream passing through a diaphragm in the critical flow mode. A practical approval of the obtained analytical solution is presented

The article reports the results of the analysis of the field prospecting activities of five exploratory wells at the Karmalinovskoye gas condensate field. We have found that the eastern part of the licensed area is characterized by the lack of fructuring in Paleozoic deposits, and the development of the productive deposit extends in the north-west direction. Hydraulic fracturing made it possible to get a stable gas and gas condensate flow rate in well № 4. This volume exceeds 3,8 times as large than flow rate in wells № 1 and № 2, which were tested after drilling without conducting hydraulic fracturing.

Rate Calculation

The mass flow rate of methane and 19 natural gas mixtures through critical flow nozzles has been calculated. The calculation assumes the flow to be one-dimensional and isentropic. The pressure range is 0 to 1000 psi and the temperature range is from 450 to 700 deg Rankine. From a study of the results, a simple empirical method for making this mass flow rate calculation is proposed. This method would apply to natural gas mixtures whose composition is known and whose components have no more than four carbon atoms.

AbstractThe thermal effects of air flow forced through a snow sample are investigated numerically. A new method for calculating vapor transport in snow is presented which allows for the determination of the effects of sublimation. In this method, the snow is not assumed to be saturated with water vapor. Results of the model show very good agreement with analytical and experimental results. The effects of heat conduction, heat advected by the dry air and heat associated with sublimation are examined in a comprehensive theory, and then each effect is isolated to determine its overall contribution. It is demonstrated that the heat transfer associated with vapor transport is significant in the determination of the overall temperature profile of a ventilated snow sample but that the major effects are controlled by the heat carried by the dry air flow through the snow and heat conduction due to the temperatures imposed at the boundaries. The thermal effects of ventilation of snow are more likely to be observed when there is a smaller temperature gradient over the entire snowpack and a greater flow rate of air in the snow than would be observed when there is a greater overall temperature gradient and lesser air-flow rate.
