二流量测试工艺在安塞长10油藏的应用

Application of Two Flow Test Process to ChanglO Reservoir of Ansai Oilfieid

目前繁重的生产任务成为制约油田不稳定试井发展的瓶颈，为了减少停井测试造成的产量损失，寻求适合安塞发展的试井工艺，在不停井测试的成功基础上尝试二流量测试。通过井号筛选，对高52区块的采油井G1井率先进行二流量试井工艺及分析评价试验．测试结果和关井恢复结果对比，得出二流量试并不仅可以取得真实的流体渗流特征和油储参数，而且可以有效减少产量损失的结论，为油田试井工艺的发展提供了可靠的借鉴经验。

The current heavy production task becomes the bottleneck which limits the unstable well test of the oil field. To relieve the capacity loss caused by the well-stop test and find the well-test technology suitable for Ansai development, we try the double-flow test on the successful base of the test without well stop. Through the selection of well models, the double-flow well test technology and the trial of analysis and evaluation are firstly carried out on the oil well G1 in Gao No.52 block. Through the comparison of the test result anti tile well-stop restoring resuh, the following conclusion is achieved： the double- flow well test can get real flow permeability property and oil reservoir parameter, and the capacity loss can be effectively reduced, thus, the reliable reference experience for the development of the well test technology of the oil field is provided.
