摘要
川西地区雷四段储层溶蚀孔径小,孔隙度低,特征复杂,气测录井显示微弱,常规录井方法难以可靠评价。通过综合应用元素录井与工程录井进行定性评价,引进RoqSCAN技术分析岩石孔径与面孔率,建立岩石密度与孔隙度的计算模型,定性与定量评价结合建立综合评价标准,最终形成了地层综合评价方法,并在川西地区雷四段7口井进行应用,解释符合率85.71%,为测试选层提供了依据。
The reservoirs of the fourth member of Leikoupo Formation in western Sichuan have small dissolution pore size,low porosity,complex characteristics,and weak gas logging show.Conventional mud logging methods are difficult to reliably evaluate.Qualitative evaluation was conducted through comprehensive application of element logging and engineering logging,and RoqSCAN technology was introduced to analyze rock pore size and plane porosity.The calculation models for rock density and porosity were established.The comprehensive evaluation criteria were established by combining qualitative and quantitative evaluations.Finally,the comprehensive formation evaluation method was formed and applied to 7 wells of the fourth member of Leikoupo Formation in western Sichuan,with an interpretation coincidence rate of 85.71%,providing a basis for testing and selecting zones.
