摘要
根据翁氏预测模型 ,文章提出了包括WengCycle产量模型、累计产量模型、开发速度模型、采出程度模型等的WengCycle峰型开发模型。该模型的初始产量和初始累计产量为零 ;当生产时间趋于无穷时 ,产量为零 ,累计产量为可采储量。使用该模型 ,无论在资料缺少的开发早期 ,还是在开发的中后期 ,都能容易地确定出油气田开发的主要指标。根据该开发模型 ,提出了确定油气田开发早期开发方案的方法和适用于油气田中后期匹配的logVD—logRp、logVD—log(ct)、logRp—log (ct)三种典型图版 ,以及这三种典型图版的匹配方法和步骤 ,这为高含水和特高含水期的开发方案调整提供了可靠的方法。该模型也可以用于智力开发、生命科学、工农业生产和经济等领域。
Based on Weng Wenbo's forecast model, the Weng Cycle peak shape development model, including production model, cumulative production model, producing rate model, and recovery percent model, etc. , arc devel oped. The original production and the original cumulative production of the model is zero. When the producing time goes to infinite, the end production will be zero, too. So, the cumulative production should be the recoverable re serves. Using the model, the main producing indexes of oil and gas fields can be decided easily even in the initial stage with few data as well as in the medium/late stage. Based on the model, it is proposed the method to determine the devel opment plan in the initial stage of oil and gas fields, the 3 typical normal charts of log VD vs. log Rp , log VD vs. log (ct) and log Rp vs. log(ct) applicable to the medium/late stage of oil and gas fields, and the methods and procedures to match the 3 charts, which provides reliable tools for the development plan adjusting in high or super-high water cut stage. The model can also be applied for intelligence devel opment, life science, and fields of industry, agriculture and economy.
