在安徽省经信委组织下,我公司“辰工致密油气生产数据分析软件”、“辰工缝洞型油藏试井分析软件”两个产品申报了2018年第三批安徽省新产品。两个产品具有专业部门出具的软件检测报告、科技查新报告,和产品用户提供的使用报告,通过经信委审核、专家评审,及相关行业征求意见,最终获得了安徽省新产品证书。

“辰工致密油气生产数据分析软件”、“辰工缝洞型油藏试井分析软件”两个产品是我公司根据油田新技术需求进行开发,包含了最新的技术和研究成果,现已经逐步应用于油田的生产开发中,未来将产生巨大的经济效益和社会效益。

辰工致密油气生产数据分析软件利用日常生产中的流量及压力数据反演地层参数,产品依据渗流力学及井筒管流等理论,对石油开采中的流量,压力等数据进行反演,并利用反演参数进行产能预测。软件提供数百种渗流力学方程求解方法,井口到井底压力折算,传统及组合拟合分析方法,以及试井设计,产能预测和可视化显示功能,并创新性地提出虚拟等效生产时间方法,将改变工作制度时刻的平均压力代替下一生产阶段的原始压力,将实际数据等效转换为分段连续数据,合理修正原始地层压力,从而解决实际油井频繁改变工作制度导致数据突变问题。

辰工缝洞型油藏试井分析软件针对缝洞油气藏的储层特点,开展油气状态方程、岩石本构关系等研究,建立地层条件下考虑油气状态及岩石本构的基岩-缝-洞组合的渗流方程,按照井、缝洞及渗流三种类型进行试井模型建立,提出符合缝洞型特点的新模型和缝洞型油藏试井新模型方程求解以及缝洞型油藏试井全历史拟合算法,从而形成了能够求出洞体积、距离等断熔体特色解释参数的试井方法,特色缝洞解释结论与动态认识吻合率大于80%。

我公司一直从事石油工程软件的研发,此次研发的产品得到省经信委的认可,我们感到无比激动及欢欣鼓舞,公司将再接再厉,争取更大的进步,为技术发展做出贡献。

Under the organization of Anhui Economic and Information Commission, our company "Chengong Dense Oil and Gas Production Data Analysis Software" and "Chengong Fracture-hole Type Reservoir Well Testing Analysis Software" two products declared the third batch of new products in Anhui Province in 2018. The two products have the software inspection report, the science and technology novelty search report issued by the professional department, and the use report provided by the product user, through the Economic and Information Commission verification, the expert review, and the opinion asked from related industries, finally obtained the Anhui Province new product certificate.

"Chengong Dense Oil and Gas Production Data Analysis Software" and "Chengong Fracture-hole Type Reservoir Well Testing Analysis Software" are developed by our company according to the new technical requirements of the oil field, including the latest technology and research results, which have been gradually applied to the production and development of the oil field, and great economic and social benefits will be produced in the future.

The Chengong Dense Oil and Gas Production Data Analysis Software uses the flow and pressure data in daily production to retrieve formation parameters. According to the theories of seepage mechanics, wellbore pipe flow and so on, the data of flow and pressure in oil exploitation are inversed, and the productivity prediction is carried out by using the inversion parameters. The software provides hundreds of seepage mechanics equation solving methods, wellhead to bottom hole pressure conversion, traditional and combined simulation analysis methods, well testing design, productivity prediction and visual display functions, and innovatively puts forward the virtual equivalent production time method, which replaces the original pressure in the next production stage by changing the average pressure of the working system time, and equivalent converts the actual data into piecewise continuous data. The original formation pressure is corrected reasonably, so as to solve the problem of data mutation caused by frequent change of working system in actual oil wells.

According to the reservoir characteristics of fracture-hole reservoir, Chengong fracture-hole type reservoir well testing analysis software develops the oil and gas state equation, rock constitutive relation and so on research. The seepage equation of bedrock-fracture-hole combination considering oil and gas state and rock constitution under formation condition is established, and the well testing model is established according to the three types of well, fracture-hole and seepage. A new model in accordance with the characteristics of fracture-hole type, the solution of the new model equation of fracture-hole type reservoir well testing and the full history simulation algorithm of fracture-hole type well testing are put forward, thus a well testing method which can calculate the characteristic interpretation parameters of fracture melt such as hole volume and distance is formed, and the coincidence rate between the interpretation conclusion of characteristic fracture hole and the dynamic cognition is more than 80%.

Our company has been engaged in the research and development of petroleum engineering software, the researched products have been recognized by the Provincial Economic and Information Commission, we are extremely excited and cheered, our company will continue to work hard, strive for greater progress, and contribute to the development of technology.
