储集层预测技术在沙南油田开发中的应用
|
摘要
长期的开发实践表明岩性油藏的开发一直带有高风险性，主要原因在于对有利岩性的展布预测存在不确定性。采用井约束波阻抗反演、地震相分析、储集层参数预测等方法，针对水下浊积扇沉积环境形成的沙南油田梧桐沟组构造岩性油藏，开展了储集层横向预测研究，指出的浊积砂体的展布范围，经开发实施证实，预测结果是可信的，表明多种储集层预测方法的综合应用对岩性油藏的准确预测具有重要作用。
： Long－term development practices showed that the development of lithological reservoir had been risky．The main reason is the uncertainty of the distribution prediction for the favorable lithology． The paper made an attempt to carry out study on the lateal reservoir predictions by applying such methods as impedance inversion of well－constraint waves， seismic factes analysis and reservoir parameter prediction with view to structural lithological reservoir in Wutonggou formation of Sha＇nan oilfield formed under the turbidite fan depositional environment， and pointed out the distribution range of the tyrbidite sandbody． Through practical development， it is proved that the prediction result is reliable． This indicates that integrated application of multiple reservoir prediction methods play an important role in accurate prediction of lithological reservoirs
