胜利探区隐蔽油气藏高精度勘探地震采集技术进展

The progress of high-precision exploration seismic acquisition technology of subtle reservoir in ShengLi exploration area

为满足隐蔽油气藏老油田进一步勘探开发对地震成像精度的要求,胜利油田不断研究、发展和完善高精度地震采集技术和方法,来提高野外原始地震资料品质.在胜利探区,针对复杂岩性隐蔽油气藏勘探的实际需求,对影响地震资料品质的高密集空间采样观测系统设计、近地表结构探测与建模方法、新型炸药震源研制与激发技术、数字检波器接收及低噪声施工等地震采集技术环节进行了重点研究,取得了一系列成果,进一步发展和完善了高精度、高密度地震采集技术系列.在胜利油田YX、B12和LJ等多个地区的应用显著提高了原始地震资料的品质.

To meet the requirements of further exploration and development in mature oilfields,it need to improve the quality and definition of seismic exploration data.In the exploration area of Shengli Oil Field,for actual exploration demands of complex lithology subtle reservoir,it focus to research high density spatial sampling geometry design, near-surface structure investigation and forward modeling methods,new dynamite source development and shooting technology,digital geophone receiver,low operation and other technical aspects of seismic acquisition that affect the quality of seismic data.To get a series of results and further develop and perfect the highprecision and high density seismic acquisition technology.The application of high precision seismic exploration acquisition series of new technologies in subtle reservoir in YX,B12 and LJ etc.of Shengli Oilfield significantly improves the quality of the original seismic data.
