提高S油田目的层成像质量的措施
Measures to Improve the Imaging Quality of Target Layers in S Oilfield
摘要
Abstract
The 3D data collected in the early stage of S oilfield have been reprocessed many times,but the seismic data after processing have large fuzzy zones in the favorable oil and gas areas,and the tomography imaging is not clear,which seriously affects the reasonable deployment of the follow-up exploration and development plan of the oilfield.Through previous studies,it has been recognized that fuzzy zone and unclear tomography may be related to insufficient understanding of unreasonable design of observation system acquisition parameters and local low speed zone insufficient understanding.However,how they affect imaging is fuzzy,and it is difficult to give substantive guidance to the design and processing of subsequent observation system acquisition parameters.To improve the guidance of subsequent S oilfield acquisition and processing,a two-dimensional geological model is constructed by combining interpretation seismic data,geological data,and expert experience,to analyze the imaging quality of different acquisition parameters,such as bin size,and different speed of low-speed zone.It is suggested to use the source capacity of gas gun close to 2,495 cuin,bin size using 12.5 m,shot point distance using 100 m and the maximum offset distance above 5 km to obtain high quality seismic data based on obtaining reliable low-speed belt speed.关键词
