摘要
酸压施工曲线不仅能为判定酸化施工质量、分析施工效果提供依据,还能通过储层渗透性、滤失性等多方面信息分析判断储层特征与缝洞发育情况。在此基础上对土库曼斯坦阿姆河右岸B区气田大量酸压施工曲线展开研究,根据排量与泵压变化的相互关系,识别出B区气田缝洞较为发育,与地质认识及试井解释结果基本一致。因此即使在缺乏地质资料的情况下,通过酸压施工曲线综合分析也可判断出储层缝洞发育情况。
Acid- fracturing curves may not only provide evidence for judging fracturing quality and analyzing fracturing effect,but also decide reservoir characteristics and fracture-cavity development through some information about permeability and filter-loss performance. A lot of acid-fracturing curves from B block gasfield in the right bank of the Amu Darya, Turkmenistan, were studied at first. And then, according to relationship between discharge capacity and pump- pressure change, one conclusion that both fracture and cavity in this field are more developed was gained, which is roughly identical to geological acknowledge and well-testing interpretation. So, for some reservoirs, the fracture-cavity development can be judged by acid-fracturing curves even if there is very little geologic data.
