            Products>>Products on Sale>>Chengong Node Analysis Software Series>>Chengong Oil and Gas Nodal Analysis Software

            Chengong oil and gas nodal analysis software mainly focuses on the formation seepage flow of each well, the pipe flow of wellbore and the throttling of oil and gas nozzle and the prediction of production capacity, and provides the optimization of integrated production system from underground, throttle valve and surface. In view of the geological characteristics and reservoir characteristics such as conventional oil gas reservoir, shale gas reservoir and dense gas reservoir, it is of great significance to find out the factors that restrict the production of oil and gas wells, to optimize the production process mode and recovery rate, to predict the production capacity of oil and gas wells and to optimize the production work system.

            According to the tube structure of gas test, the software can realize the calculation of oil and gas well tube flow, calculate the production under different oil nozzles, the pressure and temperature distribution in wellbore, the condition of hydride formation, the minimum production of bringing out wellbore liquid, the calculation of high pressure physical property parameters, and the analysis of conventional and dynamic production capacity based on pressure test well. These complete capacity evaluation and prediction functions can determine the reasonable capacity formulation scheme under different development modes (new well opening, stage continuous gas production well, self-jet well and long-term production well, etc.). Among them, the transient IPR curve theory, which realizes the production capacity prediction method based on the well test interpretation, can change the traditional capacity test of changing the working system many times to the test that shut-in pressure recovery only one time needed.

            Provide wellhead-bottom hole pressure conversion function: it can realize wellhead to bottom hole pressure conversion under the condition of variable production system and variable production according to different wellbore flow conditions; at the same time, it provides wellbore pressure distribution calculation and phase diagram calculation function at each time.

            Provides the function of calculating the physical properties of high pressure of oil and gas water: the calculation of the physical properties parameters of high pressure of fluid domestic and abroad can be summarized, and the oil/gas/water viscosities, compression coefficient, volume coefficient and density of oil and gas water can be calculated; gas provides a variety of non-hydrocarbon gas correction methods; oil phase provides saturation and unsaturated physical properties calculation; two phase provides tension calculation, etc.

            Provide system design function: according to the gas test to produce the tube structure, realize the oil and gas well tube flow calculation, calculate the production under different nozzles, the pressure distribution in the wellbore, the condition of hydride generation, the minimum output from the wellbore liquid, predict the dynamic production capacity, provide the integrated production system optimization from underground-throttle valve-surface.

            Provide capacity evaluation functions, including calculation of pressure, development dynamics, transient capacity, capacity well testing and flow analysis functions. has a steady-state capacity evaluation method, which can carry out conventional capacity analysis and capacity prediction based on well test interpretation; with transient IPR curve calculation function at different production times, capacity prediction can be achieved by production data analysis of variable pressure-flow.
