Warm congratulations to our company "Chengong Perforation Optimization System V3.0", "Chengong Production Data Analysis Software V1.0", "Chengong Numerical Well Testing Analysis System V3.0" three kinds of software pass the Anhui Software Industry Association software product evaluation, obtain the software product certificate.
The perforation optimization system V3.0 is developed for optimizing perforation. Under the premise of ensuring the safety of wellbore, the perforation depth is maximized. There are many parameters involved in perforation, such as perforation depth, perforation density, perforation phase angle, formation anisotropy, perforation radius and so on. These parameters all affect the production capacity of oil and gas wells after perforation. According to the actual situation of the formation, the software comprehensively considers the influence of each parameter. So that the productivity of oil and gas wells can be the largest. The software has powerful mathematical calculation and perforation optimization functions, strong applicability, flexible graphic display and system, intuitive curve data display function, and is widely used in oil fields.
Chengong Production Data Analysis Software V1.0 can realize the data analysis under variable flow rate and pressure of oil and gas wells. Through the analysis, the formation permeability, reserves and other parameters can be obtained, and these parameters can be used to predict the productivity of oil and gas wells in the future. The software provides the traditional production data analysis method, and develops the combination analysis method according to the seepage mechanics theory, which provides the bottom hole pressure conversion function for the analysis of wellhead flow and pressure data, and also provides the function of predicting the flow rate and pressure by using the analysis parameters. Among them the traditional production data analysis includes Arps method of flow decline, Fok combination analysis method, and according to the theory of pressure deviation, the data analysis of pressure difference per unit flow is provided. Its geological model is very rich, and the application range of production data analysis is extended. In order to predict the change of pressure and flow rate, the software provides a prediction method of bottom hole pressure and flow rate under material balance time, which is not only accurate in algorithm, but also can realize fast calculation. The software can be widely used in the optimization of working system and the formulation of development scheme in oil and gas well exploration and development, especially suit for the analysis of bottom hole pressure data which can not be measured in dense oil and gas development.
Chengong Numerical Well Testing Analysis System V3.0 is a well testing software based on the numerical solution of reservoir mathematical model. According to the complex well type of oil and gas well testing (inclined well, horizontal well, horizontal well multi-fracturing, etc.), multi-phase fluid, complex boundary and anisotropic oil reservoir and other pressure data without analytical solution. The numerical discrete method is used to solve the seepage equation, so as to realize the complex flow and well testing analysis of the formation. The software can interpret and analyze any complex boundary and a plurality of non-regular faults, and considers the complex situations such as multi-well interference, over-bubble point, interlayer non-uniformity, interlaminar flow and so on, the software has the geological body data loading function, supports the earth coordinate and the phase-controlled modeling function, and the three-dimensional visual display can be carried out on the oil and gas water saturation, the pressure distribution and the static parameter distribution in the formation.
The software has high technical content and stable market, it becomes the software products to sale, and has obtained great economic benefits. It is widely used in the oil field, research institute, petroleum and natural gas exploration and development and other fields, the technology is mature, nearly 10000 wells have been explained and analyzed. In the future, our company will continuously improve the technical level, meet the new challenges and create new brilliance.
