油气井压力恢复试井解释关键技术
|
摘要
为提高油气井压力恢复试井解释结果的可靠性,提出了试井解释时需注意的数据预处理和模型诊断关键技术。在对比分析各个容易出现错误的双对数曲线形态基础上,归纳出数据预处理时,应剔除非点、选取初始点、加载生产时间、筛选数据点、适度"光滑化"导数曲线,保证试井曲线形态正确;模型诊断时,慎重选择试井解释模型,掌握大量试井曲线图形,并对图形进行分析和识别,使地层参数解释定量化,利用压力对时间的导数检验法,对试井资料进行诊断。此方法从2000年开始在吉林油气田试井解释中应用1 000余井次,均达到预期效果。油气井压力恢复试井解释关键技术分析提高了地层参数的解释精度,为油藏动态描述提供可靠依据。
To improve the reliability of well test interpretation results of oil and gas wells,the key technologies of data preprocessing and model diagnosis that need to be paid attention to during well test interpretation were proposed. Based on comparative analysis of the log-log curve patterns that are prone to errors,removing the error points,selecting the initial point,loading the production time,sampling the data points and making the moderate derivative curve"smooth"should be done to guarantee correct well test curve shape during data preprocessing. During model diagnosis,carefully chosing the well test interpretation model,acquisition of a large number of well test curves and analysis and identification of them should be conducted to quantificated the interpretation of formation parameters,and the pressure-time derivative method could be used to diagnose the well test data. Since 2000,this method has been applied in more than 1 000 wells in Jilin oil and gas field,all of which have achieved the expected results. The key technologies analysis of oil and gas well pressure buildup test interpretation improves the interpretation accuracy of formation parameters and provides a reliable basis for reservoir dynamic description.
