热烈祝贺我公司“辰工射孔优化系统V3.0”、“辰工生产数据分析软件V1.0”、“辰工数值试井分析系统V3.0”三个软件通过安徽省软件行业协会的软件产品评估,获得软件产品证书。

辰工射孔优化系统V3.0是针对优化射孔而开发的,在确保井筒安全的前提下最大限度地提高射孔穿深,射孔涉及到的参数较多,如射孔深度、射孔密度、射孔相位角、地层各相异性、射孔孔眼半径等,这些参数都影响射孔后的油气井生产能力,软件根据地层的实际情况,综合考虑各参数的影响,使得油气井生产能力最大。软件拥有强大的数学计算和射孔优化功能,适用性强,具有灵活的图形显示及系统,直观的曲线数据显示功能,在油田中被广泛使用。

辰工生产数据分析软件V1.0能够实现油气井变流量及压力下的数据分析,通过分析可获得地层渗透率、储量等参数,利用这些参数可预测未来油气井产能。软件提供了传统的生产数据分析方法,并依据渗流力学理论发展了组合分析方法,为分析井口流量及压力数据提供了井底压力折算功能,也提供了利用分析参数预测流量和压力的功能。其中传统的生产数据分析包括流量递减的Arps方法,Fok组合分析法;依据压力偏理论,提供单位流量压差的数据分析。其地质模型极大丰富,扩展生产数据分析的应用范围。为预测压力及流量变化,本软件提供了物质平衡时间下的井底压力和流量预测方法,不仅算法准确,而且可实现快速计算。软件可广泛应用于油气井勘探开发中的工作制度优化、开发方案制定,尤其适用于致密油气开发中无法测量井底压力数据的分析。

辰工数值试井分析系统V3.0是基于油藏数学模型数值解的试井软件,针对油气井试井中复杂井型(斜井、水平井、水平井多段压裂等)、多相流体、复杂边界及各向异性油藏等不存在解析解的压力资料,采用数值离散方法对渗流方程进行求解,从而实现复杂流动及地层的试井分析。软件可对任意复杂边界及多条非规则断层进行解释分析,考虑了多井干扰、过泡点、层间非均匀性、层间窜流等复杂情形,具有地质体数据载入功能,支持大地坐标和相控建模功能,能对地层中油气水饱和度、压力分布及静态参数分布进行三维可视化显示。

上述软件技术含量高,市场稳定,成为软件产品销售,已取得极大的经济效益。目前在油田、研究院以及石油天然气勘探开发领域等被广泛使用,技术成熟,已解释分析资料近万口井次。今后公司将不断提高公司行业技术水平,迎接新的挑战,创造新的辉煌。

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.
