大庆探区齐家北地区含油砂岩分布预测

储层预测和油气检测中的地球物理特性主要来源于地震属性。以往地震属性是在地震常规剖面解释后提取，时窗较大，分辨率较低，针对性不强，所提取的地震属性包含了储层及其围岩的多种岩性信息，难以筛选、优化。通过对大庆探区齐家北地区的研究，改变以往的工作程序，在储层反演及岩性解释后进行地震属性提取、筛选、优化，减少了其它因素的影响，提高了储层参数预测和油气检测的精度及可信度，为寻找有利的潜在含油气区、圈定油气藏面积及估算油气储量奠定了基础。

Oil-bearing sandstone distributive characteristics in Qijiabei area of Daqing Oilfield

The geophysical properties of reservoir prediction and oil-gas detection of oil-gas geological synthetic prediction system is mainly from seismic attributes. In the past, the seismic attributes were picked up after seismic regular interpretation, the time window was bigger, the resolution was lower, and the quality was also poor, and the seismic attributes included many kinds of lithologic information of the reservoirs and surrounding rocks, which was difficult to selection and optimization. By the study of data in Qijiabei area of Daqing Oilfield, the passing work flow is changed, and the work of picking up, selecting and optimizing seismic attributes alter the reservoir inversion and lithologic interpretation is conducted, which decreases the other factors' effect, and improves the aceuracy and confident degree of reservoir parameter prediction and oil-gas detection, which is the foundation to find the potential oil-gas regions, draw oil-gas field area and and estimate oil-gas reserves.
