红台气田为吐哈已开发主力气田之一,主要含气层段为中侏罗统三间房组,区块内断层发育,砂体呈不连续块状分布,储层物性差,凝析油含量中等,属以岩性控制为主低孔低渗构造-岩性凝析气藏,在近5年的开发过程中,表现出产量、压力下降快,采出程度低等特征,为进一步挖掘气田稳产的潜力,提高气田的开发效果,对红台气田的开采特征做了分析研究,并提出了下步稳产对策。
The Hongtai gas field is one of the main gas fields developed in Tuha. The main gas-bearing section is the Sanjianfang Formation in the Middle Jurassic. The faults are developed within the blocks, with discontinuous massive sand bodies, poor reservoir properties and condensate Medium oil content, which belongs to the lithologic condensate-controlled low-porosity and low-permeability condensate gas reservoir. During the development of the past five years, it has the characteristics of rapid decrease of output and pressure, Excavate the potential of stable production in the gas field and improve the development effect of the gas field. The exploitation characteristics of the Hongtai gas field are analyzed and studied, and the countermeasures of steady production are put forward.
