摘要

摘要: 塔河油田四区主要含油层系为奥陶系鹰山组,岩性为质纯厚层海相碳酸盐岩,主要储集空间类型为次生孔隙,包括岩溶作用形成的溶蚀孔、缝及溶洞,原生孔隙不发育.依据现代岩溶水动力单元研究成果,建立岩溶概念模型,划分出渗流岩溶带(包括渗入亚带和渗流亚带)、潜流岩溶带和缓流岩溶带3个古水动力单元.应用随机地震反演技术,描述储层展布,揭示了储集层纵向上主要受控于古岩溶分带,平面上受控于岩溶古地貌单元的规律,研究成果通过实际钻井得到了验证.

Abstract: In district 4 of the Tahe Oilfield, the Ordovician Yingshan Formation was most petroliferous. Marine carbonate rocks with big thickness were widespread. Secondary pores, including dissolution pores, fractures and caves, served as the main reservoir spaces, while primary pores were poorly developed. According to modern karst hydraulic unit theory, a conceptual model of karst was established. Three palaeo-hydraulic zones were identified: vadose zone (including infiltration sub-zone and percolation sub-zone), phreatic zone and tranquil zone. The distribution of reservoirs was described using stochastic seismic inversion technology. The reservoirs were controlled by palaeo-hydraulic zones vertically and karst landforms horizontally, which was proved by field work.
