早期试井技术在陆梁油田的应用

Application of early well test in Luliang oilfield

采用基于小信号放大理论的早期试井分析方法^([1])能够较好的解决不出径向流直线段井的试井分析问题。该技术在新疆陆梁油田进行了推广,为验证方法的正确性与适用性,对不同物性不同模型的实验井截取较短的压力测试数据进行解释并对比。证明了早期试井拟合方法可解决低渗透油田不出现径向流直线段的压力资料解释问题;并且在保证测试资料能真实地反映测试井的模型及地层参数下,对中高渗油藏适当的缩短关井时间,减少测压占产时间,提高经济效益。

The early well test analysis method is based on a small signal amplification theory, it can solve the problem of no radial flow straight line segment in well testing. The technology is applied in LuLiang oilfield. The short pressure test data from experimental wells with different properties and models are interpreted and compared to verify the correctness and applicability of the method. It proves that the early well testing method can solve the problem of on radial flow straight line in pressure data interpretation for low permeability oil field;it can be used to reduce time of test and pressure measurement,improve the economic benefits of the mid&highpermeabilityreservoirsandensurethetestdatacantruly reflectthewelltestmodelandreservoir parameters.
