根据泥岩的压实作用规律,利用多口井的声波时差曲线值,根据陈荷立提出的平衡深度法计算延长组长6、7、8的压力值并分析研究区的地层异常压力及分布特征。根据绘制的异常压力平面分布图并结合已经发现的油藏分布图,分析得出长8为A地区的主要勘探层位;压力差正值分布区域可决定产油井位的布置;长7与长6、长7与长8的压力差存在负值,可能与岩性有关。
According to the law of compaction of mudstone, the pressure of multi-well acoustic wave is used to calculate the pressure of extension group 6, 7 and 8 according to the equilibrium depth method proposed by Chen Heli and the stratigraphic abnormal pressure and distribution characteristics are analyzed. According to the plot of the abnormal pressure plane and the reservoir distribution maps that have been found, it is found that the main exploration horizon is located in area A of Chang 8; the distribution of positive pressure distribution determines the layout of oil production wells; 6, there is negative pressure difference between long 7 and long 8, which may be related to lithology.
