基于传统的压实理论和经典的地层压力剖面求取方法 ,充分利用测井资料处理技术优势 ,在编制出地层压力剖面处理软件后 ,用该软件对柴达木盆地北缘冷湖 -南八仙构造带及西部的油泉子 -油南构造带的若干口重点井进行处理 ,并结合钻井、地质、钻井液及 RFT测试资料对上述 2个探区的地层压力变化规律进行较为系统的研究 ,计算的地层压力与试井求压资料误差多在 7%以内 ,基本上可以满足钻井工程设计及施工的需要 ,为上述 2个探区今后的钻探工作提供了较为科学的指导依据。该套软件及研究方法完全可以在柴达木盆地推广应用。
Based on the traditional compaction theory and classical method of obtaining formation pressure profile, taking full advantage of logging data processing technology, after software of formation pressure profile processing was compiled, the software was used to analyze the cold lake - Nanbaxian Tectonic belt and a number of key wells in the Yubeizi-Younan structural zone in the west of China. The formation pressure variation of the two exploration zones was systematically studied based on drilling, geologic, drilling fluid and RFT test data. The stratum pressure and well test pressure data error are mostly within 7%, basically meeting the need of drilling engineering design and construction, which provides a scientific guideline for the future drilling work of the two exploration areas. The software and research methods can be widely applied in the Qaidam Basin.
