摘　　要：苏里格气田是我国大型低渗透砂岩气藏,非均质性强,经济开发难度大,随着气田勘探开发的深入,大量资料均表明气田西部发育小型断层及裂缝,而在该类井区,气井静态参数一般,却生产效果较好,为了提高开发效果,优化水平井部署,降低开发成本,在苏X区块开展了裂缝识别方法研究.研究表明基于相干体的三维地震解释技术可以较好地预测该区小型断层发育规模,基于R/S分形技术优化的测井解释技术可以定性预测裂缝规模,应用取芯井及成相测井的裂缝描述标定,可以实现半定量的裂缝预测.Sulige gas field is a large low permeability gas field in China,it has strong heterogeneity,economic development is difficult,with the deeper exploration and development of gas fields,a large numberof data showed that the western of gas field had small faults and fracture. Dynamic production showedthat small faults and fracture zones had good gas production effect,in order to improve the development effect,optimize arrange horizontal well deployment and reduce development costs,we carried out fracture identificationmethods research in Su X block,the research indicated that 3D seismic coherence studies could explain andpredict the small scale faults better than other technology,and based on R/S method optimization interpretationtechnique of logging can qualitatively predict fracture,using the coring and fracture phase logging calibration,can realize the semi-quantitative prediction of fracture.
