摘要/Abstract

摘要： 利用地质、测井特征标志及特色岩石相，开展四川盆地涪陵地区水平井的页岩岩石相标定。根据岩性组合、炭质含量及硅质含量3大关键标志，将涪陵地区典型导眼井下志留统龙马溪组89m厚的大套页岩段划分为9种不同类型的岩石相。根据标志层、炭质染手和粉砂质纹层等地质特征标志，以及测井响应的异常值、测井形态类型、挖掘效应、假挖掘现象等测井特征标志，明确了①，③和⑥号岩石相为特色岩石相。通过水平井“水平段垂直投影法”及垂直投影后的测井信息等结果，并与典型导眼井的岩石相特征标志、特色岩石相进行对比，确定了水平井井轨迹穿行的岩石相顶、底边界，完成了不同类型的岩石相标定。依据岩石相与压裂试气产能的关系，寻找特高产、高产水平井的岩石相类型，发现①和③号富碳高硅岩石相具有高产潜力，明确①和③号岩石相为最佳岩石相。根据最佳岩石相原则，从地质角度建议水平井最佳井轨迹或靶窗着陆点宜在①号与③号最佳岩石相之间穿越。该方法已应用于四川盆地涪陵页岩气田，依据岩石相标定方法的产能预测与压裂试气结果的吻合率大于80%，它在反馈优化井轨迹和提高单井产能等方面具有很好的推广应用前景。

Abstract: Petrological facies calibrations were performed on shale of horizontal wells in Fuling,Sichuan Basin,based on geological and well-logging characteristic marks,and specialized petrological facies.In accordance with the three key marks (lithological combination,calcareous content and siliceous content),the whole set of 89-meter-thick shale interval in the typical pilot wells of the Lower Silurian Longmaxi Formation in Fuling were divided into nine different types of petrological facies.The No 1,3 and 6 petrological facies were identified as specialized petrological facies based on geological marks like marker beds,carbon dyes and silty laminae as well as logging marks such as logging response anomaly,the types of logging curve shape,excavation effect and pseudo excavation effect.We compared the results of projected well-logging information through horizontal section-based vertical projection with characteristic marks and specialized petrological facies in typical pilot wells to determine the top and bottom boundaries of the petrological facies and accomplished the calibrations.The relationship between petrological facies and the post-fracturing tested productivity was used to identify the petrological facies in prolific horizontal wells.It was found that the petrological facies with high calcareous and silica contents (No.1 and 3 facies with) have the greatest productivity potential,thus were determined to be the best petrological facies.Based on the principle of the best petrological facies,we suggest the best trajectory of horizontal well or landing point of target window be between the No.1 and 3 facies.Application of the calibration method to Fuling shale gas field were positive,with the coincidence rate between the predicted and tested productivities being more than 80%,proving it a potential method for optimizing well trajectory design and increasing single-well production.
