摘　　要：扬—恰气田位于土库曼斯坦阿姆河右岸B区块中部,是阿姆河天然气公司第二处理厂的主供气田之一。针对气藏受构造和岩性控制、储层纵横向上非均质性较强、井网密度低、超高压的特征,将方案中新钻开发井设计为大角度斜井,以扩大泄气面积、提高储层动用程度;同时应用地震预测和数值模拟技术,结合钻井、测井、试油和沉积相等资料进行了目标优选。Located at the central B block,right bank of the Amu Darya River in Turkmenistan,Yangui-Chashgui gasfield is one of the main gas resources for No.2 Gas Processing Plant of Amu Darya River Natural Gas Company.In this field with low well-spacing density,gas reservoirs are controlled by structure and lithology and are characterized by stronger heterogeneity transversally and longitudinally,and ultra-high pressure.So,high-angle deviated wells as newly drilled development ones,are designed.This design can not only enlarge the drainage area but also increase the producing reservoirs.In addition,based on sedimentary facies,and drilling,well-logging and well testing data,many problems occurring are further studied by means of both seismic prediction and numerical simulation.In general,our study may provide a reliable geological basis for design of high-angle deviated wells.
