断层式潜山界面,在现场卡取过程中,很难有固定的规律可以依循。为了提高断层式潜山界面卡取的准确率和及时性,本文对现场录井过程中断层式潜山界面的卡取过程进行了总结研究。按照“钻前预测-钻中控制-钻后总结”的工作流程。首先,做好钻前分析;其次,在钻进过程中,加强与邻井的地层对比,做好随钻地质预告,并根据实钻地层做出调整;再者,制定切实可行的潜山界面卡取施工措施;最后,要根据鉴定结果或后续钻进情况进一步判断地层,总结经验。
Fault buried hill interface, in the process of card access, it is difficult to have a fixed law can be followed. In order to improve the accuracy and timeliness of fault-type buried-hill interface card, this paper summarizes the card-picking process of fault-type buried hill interface in the process of field logging. Follow the workflow of “Predict Before Drilling - Control in Drill - Summary After Drill”. First of all, do a good pre-drill analysis; Second, during the drilling process, to strengthen the stratigraphic comparison with the adjacent wells, drilling geological prediction to do well, and make adjustments according to the actual drilling formation; Furthermore, the development of practical buried hill interface Take construction measures; Finally, according to the identification results or follow-up drilling conditions to further determine the formation, sum up experience.
