        產品展廳>>項目研發>>縫洞型儲層產能評價方法研究

        油藏受斷溶控制,縫洞結構復雜、組合模式多樣,且井間連通狀況好,單井產能評價和預測需綜合考慮縫洞結構和井間連通性影響。通過項目研究,在廣泛掌握現有各類產能評價方法的基礎上,結合油藏實際特點,分析縫洞型油氣藏產能評價影響因素,針對性的開展瞬時和長期產能評價方法研究,形成斷熔體縫洞型油氣藏不同開發方式下的合理產能評價、預測技術,最終編制形成軟件,高效便捷的服務現場產能評價工作。

        軟件采用組件模式進行軟件研發。

        由產能試井進行產能預測是國內外普遍采用的方法,但產能試井方法自上世紀50年代提出以來一直沒有改進,由于產能試井要求每個流量下的壓力必須穩定,在實際的產能試井中,井底壓力往往難以穩定,導致產能預測結果存在誤差,同時計算的產能不隨時間變化。針對縫洞型油氣藏產能評價及預測,目前國際上還沒有相關產品。

        Products>>Project Development>>Study on Productivity Evaluation of Fracture-Hole Reservoir

        The reservoir is controlled by fault solution, the fracture and hole structures are complex and the combinations are various, and the cross-well connectivity is good. The influence of fracture-hole structure and cross-well connectivity should be considered comprehensively in the evaluation and prediction of single well productivity. Through the project research, on the basis of the existing productivity evaluation methods, combined with the actual characteristics of the reservoir, this project analyzes the influencing factors of productivity evaluation of fracture-hole oil and gas reservoirs, carries out the research on instantaneous and long-term productivity evaluation methods, and forms reasonable productivity evaluation, prediction technology under different development methods of faulting solution fracture-hole type oil gas reservoir, finally the software and the efficient and convenient in-situ service and production evaluation are completed.

        The calculation of high pressure physical parameters of fluid in formation, according to the high physical parameters of oil phase, the laboratory measured values are used in the productivity calculation as far as possible, and the components provided by this software are usually calculated under the condition of lacking laboratory measurement data.

        The conventional productivity calculation methods of oil wells are: Vogel productivity, Fetkovich productivity, Jones productivity, Wiggins productivity, and the empirical formula of productivity in Shunbei area.

        The flow mathematical model of fracture-hole reservoir is established.

        Study on dynamic productivity method of fracture-hole reservoir.

        The software adopts the component mode to carry on the software research and development.

        Productivity prediction by productivity well testing is a widely used method domestic and abroad, but the productivity test method has not been improved since 1950s. Because productivity testing requires that the pressure under each flow rate must be stable, in the actual productivity test, the bottom hole pressure is not stable, resulting in errors in productivity prediction results, and the calculated productivity does not change with time. At present, there are no related products in the world for the evaluation and prediction of fracture-hole oil and gas reservoir productivities.
