摘要
大涝坝是一个整装的砂岩凝析气藏，衰竭式开发过程中，地层压力下降快，边水侵入气井见水，同时地层反凝析严重，气油比升高，气藏采出程度低，严重影响了气藏开发效果。为改善开发效果和提高采收率，将对该气藏实施注气保压开发。通过调研国内外凝析气藏注气开发中遇到的气窜、波及效率、吸气能力等问题实例，结合大涝坝开发特点，总结了大涝坝循环注气可能面临的问题，并提出了改善注气效果的几点建议。
Abstract
The Dalaoba Gas Condensate Reservoir is a fully-equipped sandstone one. In the procedure of depleted exploitation, formation pressure drops quickly and edge water intrudes into gas well. Strata retrogrades condensation seriously and the gas/ oil ratio increases. The recovery rate of gas reservoir decreases. Gas is injected to maintain pressure so as to improve development efficiency and recovery rate. By surveying and studying the examples of gas breakthrough, conformance efficiency, ability of air intake and many other problems encountered in condensate gas reservoir exploitation home and abroad, combining with the characteristics of the Dalaoba Gas Condensate Reservoir, the problem may be faced in cyclic gas injection is summarized, and several proposals are raised to improve the efficiency of gas injection.
