摘要/Abstract

摘要：

碳酸盐岩底水气藏储集层复杂多样,储集层中裂缝发育,导致气井出水,气藏开发效果差。以土库曼斯坦阿姆河盆地BTU碳酸盐岩气田为例,通过分析研究区地质特征,明确了裂缝发育特征,揭示了气井高产的有利因素。基于水体能量评估结果和储集层物性特征,细分丘滩体水侵储集层类型,评估不同类型气藏水侵风险。分析不同类型气井生产动态,总结气井出水动态特征和产量递减规律,结合国内外控水采气经验,从而提出不同水侵特征类型储集层高效开发对策。

Abstract:

Carbonate gas reservoirs with bottom water are characterized by complex and diverse lithologies. Fractures are developed in these reservoirs, resulting in water production from gas wells and poor reservoir development effects. Taking the BTU carbonate gas field in the Amu Darya basin of Turkmenistan as an example, by analyzing the geology of the study area, the characteristics of the fractures were clarified, and the favorable factors for the high yield of gas wells were revealed. Based on the results of the water energy evaluation and the physical features of the reservoir, the water-invasion mound-shoal reservoirs were subdivided into different reservoir types, and the risks of water invasion were evaluated for different types of gas reservoirs. The water production performance and the production decline law were summarized through analyzing the production performances of different types of gas wells. Based on the water control and gas production experience at home and abroad, efficient development strategies for the reservoirs with different water invasion characteristics were proposed.

Key words: Turkmenistan, carbonate rock, mound-shoal reservoir, reservoir with bottom water, fracture, productivity decline law, water invasion, development strategy
