摘要：High-quality seismic geometry is the key to obtain high-quality seismic data, and can affect the accuracy of data processing and imaging. Based on the analysis of the relationship between the quality of the geometry and the four acquisition parameters(the number of traces, shot line spacing, and the space and number of receiver lines), a quality evaluation method of the geometry based on comprehensive quality factor(CQF) is proposed, and the relationship between the geometry quality and the four parameters is given. We use field data collected in an oil field in Western China with complex geology: First we use a wide azimuth geometry. Then, we calculate the relationship curve between geometry and data quality by varying each parameter while keeping the rest fixed. and the analysis results are given by using the CQF evaluation method. The results show that the shot-line spacing has the greatest effect on the quality of the geometry, and the increase of the receiver line spacing can appropriately improve the quality of the geometry, and the increase of the number of receiving traces can improve the geometry quality. The different acquisition parameters have different effects on the imaging quality of shallow and deep events. The model forward and prestack depth migration are used to generate prestack depth migration profiles with different acquisition parameters. The imaging results are consistent with the above calculated results. According to the depth of the target layer, the quality factor evaluation method is applied to guide the design of the geometry and optimize the acquisition parameters to improve the imaging accuracy of seismic data.

摘要：为了提高低渗油藏CO_2驱单井计量装置在采出液高气液比工况下,计量数据的准确性,有必要对目前各油田CO_2驱采用的翻斗称重计量工艺进行优化设计。采用立式分离及气液两相分线计量的工艺,在计量装置的出液管线上安装质量流量计,出气管线安装旋进旋涡流量计,同时在装置内部气线出口加装机械式浮球阀,从而解决在高气液比工况下翻斗称重计量适应性较差的问题。所以,采用立式分离,装置加装机械式浮球阀及质量流量计对提高严苛工况下CO_2驱单井计量数据的准确性,实现油田精细化及数据化管理有重要作用。
