影响黄土地区地震崩滑敏感性的宏观因素包括活动地质构造、地震断层、地层、地形、水文条件、地震强度等。
The macroscopic factors influencing sensitivity of seismic loess landslides include geological structure, seismic fault, stratum, topography, hydrological condition, seismic intensity etc.
对于应力敏感性强的储集层，过低的井底压力降低了近井地带地层的孔隙流体压力，导致裂缝趋于闭合。同时，井壁失稳的可能性也大。
To strong stress sensitivity formation, low BHP reduces pore fluid pressure of near wellbore are which results in the closure of formation fracture.
储层中敏感性矿物以粘土矿物为主，次为含铁和含钙镁矿物，其它地层微粒较少。
The sensitivity minerals of the reservoir take the clay minerals as the main, the second is the minerals contained Fe, Ca and Mg, the other formation particles is smaller.
