摘要
将井壁取心技术应用于油田开发中,评价油层的水淹程度。经过与密闭取心资料、试油结果以及油井环空资料进行对比,认为对于薄差油层,井壁取心分析的水淹程度高于参数解释结果,与密闭取心资料对比基本符合率为80.0％,与环空资料对比,二者符合较好。说明应用井壁取心资料从分析原油的地球化学性质来识别油水层,了解油层水淹状况,可以提高薄差油层的水淹识别精度。
Sidewall coring techniques are used in field development to determine the watered out degree. Based on the comparison with sealed coring data, oil testing results and profile-log of production, it is suggested for poor and thin layers that the watered out degree from sidewall coring is higher than that from log interpretation, the coincidence rate with sealed coring data is 80. 8% , and the coincidence rate with profile - log production data is very high. The re-suits suggest that on the basis of sidewall coring data, oil and water layers identification is made according to analysis of geochemical properties of crude oil, which can improve the watered out identification degree of thin and poor oil reservoirs.
