摘要
建立准确的孔隙压力剖面、坍塌压力剖面及破裂压力剖面是科学化钻井的一个重要要求,是确定钻井液密度、合理井身结构设计以及完井方法的主要依据。地层压力评估软件综合了目前国内外常用的解释计算方法,将地质、地震、测井、钻井、测试以及室内实验等各方面的数据与地层压力问题有机地结合起来,使三项压力的计算、分析更为系统化,并逐步精确化。实际应用表明,该软件的评估结果与实际测试结果基本一致,证明了该软件的精确性、可靠性与实用性。
Accurate establishment of pore pressure profile, sloughing pressure profile and fracturing pressure profile is an important request for the scientific drilling; it is the main base for the determination of drilling fluid density, reasonable casing program design and well completion methods as well. Formation pressure prediction software integrates the current commonly - used interpretation and calculation methods at home and abroad, and combines with various data, such as geology, seism, logging, drilling, testing and in - house experiment etc. , it makes the calculation and analysis of three - pressure more systematization and more accuracy. Practical application shows that the predication results of the software are consistent with the practical testing results. It is proved that the software is accurate and reliable and practical.
