摘要/Abstract

摘要： 渤海油田旅大区块的录井综合解释研究常受到复杂钻井情况影响,与以往录井解释形成的规律性认识相悖,难以形成区块统一规律性认识,而且受工程因素、人为因素影响,作业中的数据质量及资料可用性把控难度大,油气、地层信息识别难,不利于落实后续试油决策。为此,通过钻前邻井资料精细对比分析,甄别复杂井况条件下,随钻过程中各单项录井资料质量,合理分配各单项录井资料的应用权重,精准判断储层流体性质及预测原油密度,钻后测试流体精细对比分析,为现场作业及试油实时决策提供了强有力的技术支持。

关键词: 复杂井况, 数据质量, 流体性质识别, 原油密度预测, 指导试油

Abstract: The comprehensive logging interpretation under complex drilling conditions in Luda Block of Bohai Oilfield is contrary to the past regular understandings in logging interpretation,making it difficult to form a unified regular understanding of the block. Affected by engineering and human factors,it is difficult to control the data quality and data availability in operations,and to identify hydrocarbon and formation information,which is unfavorable for the implementation of subsequent oil testing decisions. Therefore,adjacent well data before drilling is finely compared and analyzed to screen the quality of mud logging data of single wells while drilling under complex well conditions,of which the application weight is reasonably allocated,the reservoir fluid properties are accurately determined and crude oil density is predicted,and test fluids after drilling are finely compared and analyzed,providing strong technical support for on-site operations and real-time decision-making for oil testing.

Key words: complex well condition, data quality, identification of fluid property, prediction of crude oil density, guidance for oil test
