| 摘 要： | 密闭取心能够提高岩心分析资料的准确性。通过水平段密闭取心,可以检验水驱油效果、定量分析油层的油水动态及剩余油分布情况。这对制定有效的增产增效措施、提高特低丰度油层单井产量和储量动用程度、完善开发方案等有着重要的意义。与直井密闭取心相比,水平井密闭取心难度更大。在进行水平段密闭取心技术难点分析的基础上,从井眼轨迹控制、钻具组合优化设计、取心工具配套和取心参数优选等几个方面进行了研究,并在树35-平27井进行了现场应用,取得了良好的应用效果。

| Abstract: | Sealed coring can improve the reliability of core analysis data.Water displacing oil efficiency can be inspected;quantitative analysis can be made on the oil-water reservoir dynamics and remaining oil distribution of oil layer through horizontal well sealed coring.This has great significance for making effective production and efficiency increasing measures,increasing individual well producing rate of extremely low abundance layer and reserve producing level,improving the exploitation plan and so on.Sealed coring is more difficult in horizontal well than in vertical well.Based on the analysis on the technical difficulties of sealed coring in horizontal well,the study was made in well trajectory control,bottom hole assembly optimization design,coring tools matching and coring parameters optimization.Good application effect was achieved in Shu35-P27 well. |
