Abstract

A new algorithm based on B-splines was proposed to consider the rate measurement error during pressure deconvolution.Several methods were provided to determine the actual rates for each flow period,which can be utilized to determine the actual pressure response in turn.The results show that unit-rate pressure response with 10% rate error agrees well with the true results,which is much better than that from ILK model.The new algorithm can overcome the effect of rate measurement error on the pressure response.

一种考虑速率测量误差的b样条压力反褶积算法及其应用

针对压力反褶积过程中的速率测量误差，提出了一种基于b样条的新算法。提供了几种方法来确定每个流动周期的实际速率，这些方法可以用来确定实际压力响应。结果表明，在速率误差为10%的情况下，单位速率压力响应与真实结果吻合较好，大大优于ILK模型。该算法克服了速率测量误差对压力响应的影响。

期刊介绍： Journal of China University of Petroleum (Natural Science Edition) was founded in 1959. It is a comprehensive academic journal with distinct petroleum characteristics, supervised by the Ministry of Education, sponsored by China University of Petroleum (East China), and publicly issued at home and abroad. It focuses on publishing innovative achievements and high-level papers in the fields of geology and exploration engineering, geological energy extraction engineering, energy equipment and control engineering, energy chemistry and materials engineering. The journal is a Chinese core journal, a statistical source journal of Chinese scientific and technological papers, and a source journal of the Chinese Science Citation Database. It is fully included in many domestic databases such as the Chinese Science Citation Database (CSCD), China National Knowledge Infrastructure, Wanfang Data, Chongqing VIP, and China Petroleum Abstracts; and has entered the Engineering Index (EI), Scopus database, the American Chemical Abstracts (CA), the American Petroleum Abstracts (PA), the Russian Abstracts Journal (AJ), the American Cambridge Scientific Abstracts: Materials Information (CSA:MI), the Japanese Bulletin of Scientific and Technical Literature (CBST), the American Stephens Database (Eh), and the American Geological Reference and Preview Database (GRP).
