抽汲井液面恢复解释软件的研制与应用

Development and application of swabbing well liquid recovery interpretation software

利用液面检测仪检测动液面数据并进行地层参数解释,是今后求取地层参数的热点方向。传统测试方法在钻柱测试时需下钻柱,电缆测试时需下电缆,压力恢复测试时需要停产。与之相比,该方法具备以下优势:投入成本较低,测试时不需停产,也不存在施工风险,可随时进行测试,只需在抽汲井口安装一套超声波液面检测仪即可。文中给出了一种利用动液面深度数据进行试井的方法,并利用VS2010在Windows环境下研制出一套抽汲井液面恢复解释软件(SWLRIS)。详细介绍了软件的设计流程、算法思想及应用结果。其结果表明,该软件解释结果与常规解释方法基本一致;解释结果可信,具有较好的应用价值。

To interpret fonnation parameters using the working fluid data obtained by the liquid level detector is undoubtedly the hot point direction of formation parameter interpretation in future. Compared with the traditional testing methods such as the putting drill string required when drilling stem testing, downloading the test cable required when the cable testing and stopping produelion required when the pressure buihlup testing, this method has the following advantages： low input costs, no shutdown in testing, zero construction risk and testing at any time, but only needing to install a set of ultrasonic liquid level detector in the wellhead of swabbing well. In this paper, the author proposes a method that can do the well testing by use of the surface pressure data and develops a set of well testing software, which is named swabbing well liquid recovery interpretation software （SWLRIS）using VS2010 in Windows environment. This paper describes in detail the design process, algorithm thinking and application results of the software. Application resuhs show that the interpretation results of this software are consistent with that of conventional interpretation and are credible, having a good application value.
