摘要
针对水平井钻井施工作业过程中地质层位的准确卡取、钻头于目的层中水平顺畅钻进以及储集层油气显示精细识别评价等现场录井需要,系统分析了水平井钻进时相关录井测量参数、LWD随钻测井实时采集处理参数的变化规律及曲线特征,采用全烃与自然伽马,深、浅侧向电阻率,气测录井烃湿度比和平衡比曲线交汇方法,利用随钻录井图在水平井地质导向层段即水平钻进阶段快速综合解释评价地层的岩性变异、储集层物性、油水界面和含油气水情况等石油地质信息。将其在大港油田2口水平井的成功应用实例进行了介绍,对水平井现场作业、阶段措施调整和后期综合决策有一定的指导意义。
In accordance with wellsite mud logging demands,such as the accurately fetching the geologic horizon,bit smoothly and horizontally moving in target zone and meticulously dis- tinguishing and evaluating oil,gas shows in reservoir during horizontal well drilling operation,the paper analyzed the changing rules and curve features for related mud logging measuring parameters,LWD real time acquisition and pro- cessing parameters,the curve crossing method (total hy drocarbon and natural gamma,deep and shallow lateral re sistivity,humidity ratio and balance ratio in gas logging) was adopted to comprehensively interpret and evaluate the oil and geologic information of the formation lithology disso- ciation,reservoir physical property,oil and water contact, oil,gas and water bearing in the geoguiding for horizontal well with the composite log geoguiding horizontal layer. The authors introduced 2 wells successful examples in Da- gang Oilfield and believed that the experience has a certain guiding meaning for horizontal well operation,stage meas urement and decision synthetically making at later stage.
