摘要
本文从指导致密砂岩储层压裂油井的快速选井选层,以及压裂效果评价出发,选优对储层岩性、物性和含油性敏感的自然伽马、声波时差、深侧向和深感应电阻率等测井参数,构建了储层岩石骨架评价指数与含油性评价指数,采用最大值标准化法和层次分析法计算储层分类的综合评判值,对储层进行评价分类。利用反映储层压裂改造、诊断油井生产动态的产出剖面测井参数确定各类储层的采油强度。利用该方法指导研究区油井压裂选层,以及压裂效果的评价,取得了较好的应用效果。
This paper guides the rapid well selection and formation selection of fractured oil wells in dense sandstone reservoirs, and evaluation of fracturing effect.Selection of logging parameters sensitive to reservoir lithology, physical properties and oil-bearing properties, such as Natural gamma , Acoustic time difference, Deep lateral and Deep induction resistivity.The evaluation index of reservoir rock skeleton and oil-bearing property are constructed.The comprehensive evaluation value of reservoir classification is calculated by maximum standardization method and analytic hierarchy process, and the reservoir is evaluated and classified.Using production profile logging parameters reflecting reservoir fracturing transformation and diagnosing production performance of oil wells to determine production intensity of various reservoirs.This method is used to guide the fracturing layer selection of oil wells and the evaluation of fracturing effect in the study area, and good application results have been achieved.
