  • Conventional pressure buildup/drawdown tests of wells have disadvantages such as long test time,influence on well production and difficulty in obtaining parameters of individual pay zones.In regard to these disadvantages,the authors propose two multi-zone well test methods,i.e.the variable flow rate method and flow-pressure fluctuation curve method,by using flow rate and pressure data of production logging in well tests,the downhole parameters such as formation pressure,permeability and contamination coefficient for each individual interval in the case of normal production of wells have been obtained using the two new methods and the problem of testing parameters of individual pay zones in a multi-pay zone well has been solved.Furthermore,the authors describe details of the test principle of the two new multi-zone well testing methods and cite the cases of field application.
