垦71井区井间地震数据采集方法

Cross-hole seismic data acquisition method in Keng-71 well-zone.

胜利油田物探公司利用引进的整套先进的井间地震设备,在垦71井区成功进行了井间地震试验和生产。本文主要讨论了与井间地震资料采集有关的技术设计、工程设计、参数试验、质量控制等问题,同时结合垦71地区井间地震资料采集试验和生产的实际情况,得到几点认识:采用共接收点道集观测方法施工效率比较高;井间地震施工设计和现场采集、处理过程密不可分,要根据现场情况做好二次设计,叠加次数要通过扇试验结果确定,激发间距宜小不宜大。

Using introduced a complete set of cross-hole seismic equipment, the Geophysical Exploration Company of Shengli Oilfield successfully carried out cross-hole seismic experiment and production. The paper mainly discussed the technical design, parameter test and QC relative to cross-hole seismic data acquisition, meanwhile, the following knowledge was gained in combination with the practical situation of test and production of cross-hole seismic acquisition in Keng-71 well-zone: using common-receiver-point acquisition survey method is characteristics of high operational efficiency; there is close relationship between design of cross-hole seismic operation and in-site acquisition and processing procedure, well doing secondary design is important based on in-site scenario; the folds is determined by fan test and smaller shot interval is appropriate than large one.
