松辽盆地北部岩石主要物理参数变化特征

VARIATION PROPERTY OF MAIN PHYSICAL PARAMETERS OF ROCKS IN NORTH-ERN SONGLIAO BASIN

利用已有的长源距声波测井资料建立了松辽盆地北部不同岩性主要物理参数数据库，并系统研究了这些参数的变化规律，指出了不同地区、不同层位应用地震资料进行储层描述和烃类检测的物理条件。

Using avaihble long spacing sonic logging data,data bank of main physical pa-rameters of different lithology in northern Songliao basin is established,the variation regular-ity of these parameters is collected and systematically studied.Also,physical conditions forconducting reservoir description and hydrocarbon detection by using seismic data in differentarea and different zone are pointed out.
