摘要
扬古伊气田为阿姆河右岸B区中部众多中小气田群中的一个,气田投产一年左右出乎意料地有地层水产出,且短短几个月时间产水量大幅度上升,为了明确气田出水原因,保障气藏开发效果,从气田及单井的生产动态特征入手,通过静态、动态资料的充分结合,研究了水体来源及出水类型,明确了水侵特征及水侵模式、因地制宜地提出了治水对策。近半年的生产实际证明:对于气田出水情况的分析是精准且符合实际的,对出水气井提出的降产控水(初期)、坚持自喷排水采气、降低条带采气速度、加密水样监测等生产建议是及时而有效的,达到了保障气藏高效开发的目的,气田生产相对平稳。
Located at the center of B block, right bank of the Amu Darya, Yangguyi gasfieldis just a small to medium-sized field. After one-year production, formation water appeared unexpectedly. And water yield rose greatly a few months later. In order to understand water-producing causes and achieve better development results, based on the characteristics of production performance, and the full integration of static and dynamic data, this article analyzes the sources of water body and water-producing types, determines water invasion characteristics and modes, and proposes countermeasures for water controlling. Over six-month practices show that the analysis is accurate and consistent with the actual one; the suggestions that reducing production and controlling water at the early stage, adhering flowing drainage gas recovery, lowering the rate of strip gas production, and frequently monitoring water sample are timely and effectively. At present, production is relatively smooth, and high-efficient development has achieved. That provides a technical reference for the similar gas reservoirs.
