在安徽省經信委組織下,我公司“辰工致密油氣生產數據分析軟件”、“辰工縫洞型油藏試井分析軟件”兩個產品申報了2018年第三批安徽省新產品。兩個產品具有專業部門出具的軟件檢測報告、科技查新報告,和產品用戶提供的使用報告,通過經信委審核、專家評審,及相關行業征求意見,最終獲得了安徽省新產品證書。

“辰工致密油氣生產數據分析軟件”、“辰工縫洞型油藏試井分析軟件”兩個產品是我公司根據油田新技術需求進行開發,包含了最新的技術和研究成果,現已經逐步應用于油田的生產開發中,未來將產生巨大的經濟效益和社會效益。

辰工致密油氣生產數據分析軟件利用日常生產中的流量及壓力數據反演地層參數,產品依據滲流力學及井筒管流等理論,對石油開采中的流量,壓力等數據進行反演,并利用反演參數進行產能預測。軟件提供數百種滲流力學方程求解方法,井口到井底壓力折算,傳統及組合擬合分析方法,以及試井設計,產能預測和可視化顯示功能,并創新性地提出虛擬等效生產時間方法,將改變工作制度時刻的平均壓力代替下一生產階段的原始壓力,將實際數據等效轉換為分段連續數據,合理修正原始地層壓力,從而解決實際油井頻繁改變工作制度導致數據突變問題。

辰工縫洞型油藏試井分析軟件針對縫洞油氣藏的儲層特點,開展油氣狀態方程、巖石本構關系等研究,建立地層條件下考慮油氣狀態及巖石本構的基巖-縫-洞組合的滲流方程,按照井、縫洞及滲流三種類型進行試井模型建立,提出符合縫洞型特點的新模型和縫洞型油藏試井新模型方程求解以及縫洞型油藏試井全歷史擬合算法,從而形成了能夠求出洞體積、距離等斷熔體特色解釋參數的試井方法,特色縫洞解釋結論與動態認識吻合率大于80%。

我公司一直從事石油工程軟件的研發,此次研發的產品得到省經信委的認可,我們感到無比激動及歡欣鼓舞,公司將再接再厲,爭取更大的進步,為技術發展做出貢獻。

Warm Congratulations on Our Company "Chengong Dense Oil and Gas Production Data Analysis Software", "Chengong Fracture-hole Type Reservoir Well Testing Analysis Software" Have Been Identified As New Products in Anhui Province in 2018 (The Third Batch)

Publish Date: 2018-11-15  Author: Chengong Technology Department


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.
