摘要:
针对凝析气藏开发过程中存在产量递减、气井高含水及井筒积液等问题，以渤海某凝析气田关停气井为研究对象，利用气井生产动态分析方法，结合气井的系统测试资料，明确了关停气井井筒中的积液段，利用经验公式法及Pipesim软件计算了临界携液气量、优化了气井生产管柱。为保证关停气井复产后正常生产，提出气举、涡流排液、泡排、小直径管等排液采气措施建议及实施步骤。对E4、E5、E6井井筒积液进行分析，其中E6井根据建议措施复产后，初期日产气23×104 m3，日产油15 m3。根据前期生产动态，预测五年累产气约584×104 m3。该方法可为海上凝析气田井筒积液分析及关停井复产措施提供借鉴。
Abstract:
There are some problems in the development of the condensate gas reservoir, such as production decline, high water cut of gas well and liquid accumulation in wellbore. This paper takes the shutdown gas well of a condensate gas field of Bohai as the research object. The liquid accumulation section in the shutdown gas well was found by using the dynamic analysis method of gas well production and combining with the systematic test data of gas well. By using the empirical formula method and Pipesim software, the critical liquid carrying production rate is calculated and the production string of gas well is optimized. In order to ensure the normal production for the shutdown of gas wells, some measures of gas lift, vortex drainage, bubble drainage, small diameter pipe and their implementation steps are proposed. The wellbore liquid accumulation of well E4, E5 and E6 is analyzed. The well E6 is put back to production according to the suggested measures, the daily gas output is 23×104 m3 and the daily oil output is 15 m3 at the initial stage. According to the production performance in the early stage, the accumulated gas production in five years is predicted to be about 584×104 m3. This method can be used in the analysis of wellbore fluid accumulation and the measures of shut in and resumption of production.
