大庆深层低渗透气井排液试气方法及产能评价

对大庆深层低渗透气井的早期压力曲线形态特征进行对比分析和归类，预测储层产能。根据气产量和水产量将排液、试气方法分为5种类型，针对不同气井采取不同的排液、试气方法，优化深层低渗透气井的排液、试气方法，提高气井试气施工的一次成功率和试井资料解释的优质率。对压裂前后、试采前后试气解释资料进行对比分析，利用试气资料和试采资料评价区块产能，为今后区块开发方案的编制提供依据。

Flow Back and Gas Lifting Method in Low Percolation Gas Reservoir of Deep Layer in Daqing Oilfield and Its Productivity Evaluation

By comparing, analyzing and classifying for early pressure curve shape property in deep layer and low percolation gas field of Daqing oilfield, producing potential is predicted. According to gas and water production, method of flow back and gas testing have been classified to 5 types, and for different gas wells, different flow back and gas testing methods are utilized to optimize this way to increase successful ration at once time and high quality of interpretation of testing data. By analyzing data of pre...
