地震解释井位跟踪分析

Seismic interpretation result updating with well information

油气勘探开发中井位部署主要依据地震勘探成果,但因受地震勘探分辨率和勘探精度的制约,据地震数据预测的圈闭形态、地层深度和储层特征与实际钻探状况会存在一定差异,或在钻井过程中发现新问题,需及时利用地震资料解释分析进行重新认识,提出解决方案。井位跟踪是解释人员及时获得并利用正钻井和测井信息,利用地震分析技术,对原有地震勘探成果进行确认或修正,采取相应的地震资料采集、处理和解释技术措施,获得新的地震成果,及时指导下一步钻探施工,以最大限度地提高油气勘探效益。

During the oil and gas exploration and development,well deployment mainly depends on seismic interpretation.However,there are always some differences in trap forms,stratum depth and reservoir distribution predicted from seismic data with those proven by actual drillings due to limits of seismic data resolution and accuracy.Sometimes new problems may encounter during the drilling.So seismic interpreters need to update their interpretation of seismic data,and propose new plans in time.Seismic interpretation result updating with well information is an effective tool of seismic analysis with updated drilling and logging information to confirm or correct the original seismic interpretations,and propose suitable measures for seismic data acquisition,processing and interpretation.This will be very helpful for future exploration.
