低压地层压力检测，在国内研究程度较低。本文结合松南区低压地层成因采用修正声波时差法，求取松南地区异常低压地层压力，并建立了地区性低压地层计算模式，解决了该地区地层压力检测问题。
Low pressure formation pressure testing, low degree of research in the country. Based on the origin of low-pressure strata in Songnan area, a modified acoustic time-difference method was used to obtain the pressure of abnormal low-pressure strata in Songnan area. A regional low-pressure stratum calculation model was established to solve the problem of formation pressure detection in this area.
