塔河油田碳酸盐岩岩溶缝洞型油气藏埋藏深度大、储层非均质性极强、渗流关系复杂,对这种复杂的油气藏开发是一个世界性的难题。针对该类油藏的地质特征和生产规律,以塔河油田四区奥陶系油藏为例,利用统计分析和油藏工程方法,确定了塔河油田缝洞型油藏的主要开发技术政策,包括开发程序、布井方式、合理产能、开发方式,为国内外同类油藏的开发提供借鉴。 The carbonate rock karst fractured-hole reservoirs in Tahe Oilfield have large buried depth, extremely strong reservoir heterogeneity and complicated seepage relations, which is a worldwide problem for the development of such complex reservoirs. Aiming at the geological characteristics and production regularity of these reservoirs, taking the Ordovician reservoir in Block 4 of Tahe Oilfield as an example, the main development and technical policies of fractured-cavity reservoirs in Tahe Oilfield are determined by means of statistical analysis and reservoir engineering methods , Including development procedures, well drilling methods, reasonable capacity and methods of development, so as to provide references for the development of similar reservoirs both at home and abroad.
