不稳定试井在濮城油田注水井的应用

Applications of Transient Well Test in Water Injection Well of Pucheng Oil Field

不稳定试井可以为油田稳定和挖潜解决更多的实际问题。为进一步发挥不稳定试井技术在油田开发中的决策作用 ,提高试井资料的利用率 ,开展了水井压降测试工艺 ,其具体做法是改变水井的工作制度 (即关井 ) ,以引起地层中压力重新分部 ,测量井底压力随时间的变化 ,再利用先进的试井解释暂且件 ,得到测试井的井筒、地层均质性、平均压力及边界情况 ,为地质研究提供更多。

Transient well test is a well test method widely used in coruse of oil and gas field exploration and gas field exploration and production.It can resolve more actual problems for stabilized oil production and tapped the latent power in oil field.Well test team has developed water well pressure-drop test technology,and replaced water well fixed-point pressure test in past time,in order to full play the decision-making function of transient well test technology in oil field exploitation progress further,and enhance use ratio of well test data.The material method is to change the working system of the water well(i.e to close the well),to cause the redistribution of the pressuer in the stratum.Through measuring the pressure of the well bottom over time range,and making use of advanced interpretation saftware of well test to get the homogeneousness of the well eall and the stratum,the average pressurb and the boundary situation,to provide geology section with much more and detailed dynamic material under earth.
