摘要
鄂尔多斯盆地大牛地气田是典型的具有三低特征的低孔、低渗、低压岩性气藏,通过近些年的产能建设,大牛地气田目前已进入开发中后期,一些储层厚度大,物性好的储层已经开发殆尽,在水平井施工过程中储层钻遇率明显降低,为了能更好的完成产能任务及新建产能,常规的砂岩组划分方法已经无法满足目前水平井施工的需要,储层单层的精细划分与对比技术在地质导向中就显得尤为重要,通过对目的层单层的储层精细划分与对比,分析储层展布特征,有效提高储层钻遇率。在油气田开发中、后期,单储层精细划分与对比技术将在水平井施工过程中对于有效控制地质导向轨迹具有重要的意义。
It is lithological gas reservoir which has three typical characteristics with low porosity,low permeability and low pressure in Daniudi gas field of Erdos basin.In recent years,Daniudi gas field has entered in the middle-late stage through capacity building,some of the thickness and well reservoir has been developed.The drilling rate of reservoir has been decreased during the horizontal well construction.In order to complete the production task and the new capacity,it is necessary to development for many complex gas reservoirs and producing reserves which couldn't to be use.The conventional stratigraphic classification method of sand formation can't used in horizontal well drilling.IT will be very important which the fine strata classification and correlation technology of the single bed.This is very effective to improve the drilling rate of reservoir through the fine strata classification and correlation of the single bed and analyzes the distribution characteristics of the reservoir.It will have an important role which the fine strata classification and correlation technology of the single bed in drilling of horizontal well in the later stage of oilfield development.
