摘要
针对大庆长垣油田构造解释研究的目标尺度小、断点组合难度大、井网密,断层解释尤其是小断层解释精度要求高。以大庆长垣油田北部N2X区块为例,在高保真地震处理资料的基础上,结合地震资料和井资料,利用井断点引导断层解释技术和井震结合三维可视化断层识别技术,对断点的空间归位、断层的空间组合进行落实,进一步深化了对断层的认识,提高了井震结合断层解释的精度和效率,断点组合率达到90%以上,更加客观地反映地下地质情况,为开发调整挖潜提供了可靠的技术支持。
In consideration of the problems of small target size,high difficulty of fault-point combination,dense well pattern,there was higher requirement for faulted zone,especially for small faulted zone interpretation in the structural interpretation of Changyuan Oilfield.By taking Block N2 Xin northern Changyuan Oilfield for example,On the basis of high fidelity seismic data processing and in combination with seismic data and well data.A well breakpoint guide fault interpretation technique and 3Dvisualization fault identification technology of integrating well data with seismic interpretation result are used to determine a space homing of a breakpoint and the space combination of fault and further deepen the understanding of faults,by which the accuracy and efficiency of well-seismic integration of fault interpretation are improved.The breakpoint combination rate is more 90%.It more objectively reflects the geologic situation,provides reliable technical support for development,adjustment and tapping the potential.
