摘　　要：鄂尔多斯盆地镇泾油田主要目的层位中生界延长组长8油层组,属构造-岩性油藏,储层孔隙结构复杂,非均质性强,是典型的低孔、低渗、低压油层,地层压力变化的不稳定性及因裂缝发育的裂缝压力给钻井、固井、压裂等施工带来很大的不利。声电成像和交叉偶极横波测井等特殊测井方法,具有信息丰富,分辨率高,质量可靠等诸多优点,结合常规测井,可以准确识别地应力方向。通过特殊测井方法在镇泾油田的应用,确立了镇泾油田延长组长8油层组地应力方向。The main target zone of 8th member of Mesozoic Yanchang Formation in Zhenjing Oilfield of Ordos Basin belonged to structural-lithologic oil reservoir with complex pore structure,strong heterogeneity,which was a typical low porosity,low permeability and low pressure reservoir,the instability of formation pressure changes and fracture pressure induced negative impact on drilling,cementing and fracturing operation.The special methods of acoustic logging and cross dipole acoustic logging have abundant information,high resolution,reliable quality and many other advantages,combined with conventional logging,they can accurately identify the stress direction.Through the application of special methods of logging in Zhenjing Oilfield,the stress direction is established in Yanchang Formation of Zhenjing Oilfield.
