塔里木盆地轮古西地区多地震属性储层综合预测

在塔里木盆地轮古西地区，储层的储集性能及其产能主要受储层类型的影响，寻找有利的储层类型成为地震属性储层预测的目标。通过对地震资料的目标性处理，提高了地震资料的品质。进一步通过地震属性敏感性分析，优选出平均反射强度、均方根振幅、平均能量、能量半衰时斜率以及相干属性，运用自组织模糊神经网络技术，开展多地震属性储层综合预测，指出了储层发育的有利地区。洞穴型和裂缝一孔洞型储层主要分布于该区的西北部以及西部的轮古41井东南部和轮古40井周围，其他地区这2类有利储层不发育。

Synthetic reservoir prediction of multiple seismic attributes in the west of Lungu area, Tarim Basin

The performance of reservoirs and its oil and gas productivity are mainly controlled by the types of reservoirs in the west of Lungu area,so the main aim of reservoir prediction is to find out the favorable reservoir.The quality of seismic data can be improved by seismic processing which focus on the interested time window.This procedure provide excellent database for reservoir prediction.The author selects average reflection strength,RMS amplitude,average energy,the slope of half energy attenuation time and coherent attribute to execute reservoir prediction by seismic attributes sensitivity analysis.With the technique of self-organizing fuzzy neural network,distribution of reservoir was predicted.Cavernous reservoir and fractured-cavernous reservoir are distributed mainly over northwest of region of interest,southeast of Lungu 41 well and Lungu 40 well.
