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

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.
