摘　　要：地震储层横向预测是近年来发展起来的一个新技术领域，有许多成功的应用实例，并且在一定程度上指导了油气的勘探和开发。储层预测范围内渗透性砂层的预测是一个研究较少，难度较大但又不是油气勘探中急需解决的课题。针对SG盆地WL地区储层为低孔隙率、低渗透性砂层的特点，根据预测性渗透性砂层的地质需要，本文提出了三种预测砂层和六种预测渗透性砂层的方法，并且强调了储层预测中的多学科结合、多种技术的配套使用、多种技术人员综合研究的思想。这些方法在该区应用后取得了明显的效果。Seismic reservoir lateral prediction is a new technology field developed in recent years, has manysuccereful application examples, and guides the exploration and development of oil and gas to a certaindegree. In the reservoir prediction, the prediction of permeable sands is studied fairly little and has con-siderable difficulty, but is a problem badly in need of being solved in reservoir exploration.In the light of the characteristics that the reservoir in the WL area of SG basin is of low porosity and permeabilily, I present three kinds of sand prediction methods and six kinds of permeable sand predictionmethods. The ideas of multidisciplinary integrtion, multiple technology coordinative use and technicalstaff comprehensive study are emphasized in reservoir prediction. An obvious effect has been achievedthrough the application of these methods to the area.
