摘要
潜山型碳酸盐岩已经成为胜利油区重要的油气勘探和开发目标。该文针对其储集空间存在的成因和分布规律问题,通过广泛研究,提出了岸边渗流和潜流带、岛状潜山渗流和潜流带、溶蚀孔洞和存在不渗透隔层等四种碳酸盐岩储集空间发育模式。认为目前潜山型碳酸盐岩发育的储集空间以溶蚀缝、孔、洞为主,构造成因的裂缝被溶蚀作用改造。碳酸盐岩溶蚀模式与传统的潜山构造分析相结合,有助于潜山型碳酸盐岩有效储集空间的预测和该类油藏的高效开发。
Carbonates of the buried hill type have become the important targets of oil and gas exploration and production in Shengli petroliferous province. Having investigated its origin and distribution rule, the author proposes four genetic models of carbonates which include the bank vadose and phreatic zones, island buried hill vadose and phreatic zones, solution cavity system and nonper-meable restraining barriers. The soluted cracks, pores and caves are dominant reservoir space in the buried hill type carbonates, and the cracks formed by tectonic movement are reformed by solution action. Combining solution models of the carbonate with traditional buried -hill structure analysis, it is conductive to predict effective reservoir space and develop this type of oil reservoir high effectively.
