板桥凝析油气田开发后期开采工艺技术评价

THE EVALUATION ON THE DEVELOPED STAGE PRODUCTION ENGINEERING TECHNIQUE FOR BANQIAO CONDENSATED GAS FIELD

板桥凝析油气田属于复杂断块油气田。目前该油气田已进入到开发后期,开采过程中各种矛盾日益加剧,加之地处盐田卤池和滩涂地区且生产井大部分为丛式井,严重制约了整个油气田的开发效果。为了完善该油气田开发的工艺技术、提高开发效果,对开采技术现状,主要是对具有代表性的深斜井分注、小泵深抽、斜井抽油、油气分输等工艺技术现状进行了分析及评价。

Banqiao condensated gas field which is a kind of special hydrocarbon reservoir of complicated faulted block now enters its later developing period, various contradictions are becoming intensified gradually. In addition, production wells that lie in both bitterns pool within salt field and shoals region as well as the majority of wells are clustered well. All these have restricted the developing effectiveness of the whole oilfield. A thorough analysis and adaptive appraisement have been made on current engineering and technical situation of Banqiao condensate gas field, particularly on the representative technologies such as deep deflecting well injection, deeply withdraw with small pump, deflecting well oil withdrawal, oil and gas respective transportation to improve and perfect the engineering technological assembling level in the region and enhance the developing effectiveness of hydrocarbon reservoir.
