摘要:
 大庆油田榆树林区块油井液面恢复测试时，常出现液面测试曲线混乱、不清晰和无明显液面曲线等现象，难以有效提供真实准确的油井液面恢复资料。对2015年3月-2016年10月189井次液面测试资料进行梳理，按照归纳法整理为测试曲线无液面波和测试曲线液面波位置异常两大类；针对每类问题的各个现象，从仪器、井口或井下工具，以及井下流体对仪器测试时产生的影响进行分析，提出测试前的避免措施、测试中的注意事项，以及测试后的修正方法。2017年3月-2019年10月在榆树林油田进行液面测试297井次，成功率达872%，准确率达883%，为油田试井资料的精准录取提供了依据。
Abstract:
 During the oil well level recovery test in Yushulin block of Daqing Oilfield, the phenomena such as confusion, unclear and no obvious liquid level curve often appear, which makes it difficult to effectively provide real and accurate data of oil well liquid level recovery. In this paper, liquid level test data of total 189 wells from March 2015 to October 2016 are sorted out. According to induction method, these data are classified into two categories: no liquid level wave in test curve and abnormal position of liquid level wave in test curve. According to each phenomenon of each kind of problem, the influence of instrument, wellhead, downhole tool and downhole fluid on instrument test is analyzed, and the avoided measures before the test, the matters needed to pay attention to in the test and the correction methods after the test are put forward. From March 2017 to October 2019, 297 wells in Yushulin Oilfield were tested by this method, and the success rate was 872% and the accuracy rate was 883%, which provided a basis for accurate logging of well test data.
