摘要
塔里木盆地北部地区碳酸盐岩油藏储层非均质性较强,只依靠常规测井判断碳酸盐岩裂缝、溶孔、溶洞很困难。而结合地层微电阻率扫描成像,就能对碳酸盐岩储层进行定性分析、定量解释,并能准确识别出碳酸盐岩裂缝性质、渗透能力、溶蚀孔洞原生孔隙、次生孔隙的发育情况等,同时还能够利用测试结果验证成像测井解释的有效性。论述了塔里木盆地轮南潜山碳酸盐岩油藏储层参数的解释方法及其效果。该方法结合了常规测井和成像测井资料,克服了横向探测深度和非均质性的影响。通过对非均质储层物性、裂缝分布规律的分析,提高碳酸盐岩中的测井解释准确性,最终达到精确评价碳酸盐岩油藏的目的。
The carbonate reservoirs in northern Tarim Basin are highly heterogeneous. It' s hard to identify fissures and caves by using conventional logging. By integrating resistivity image logging techniques, logging information can be well used to qualitatively analyze and quantitatively evaluate carbonate reservoirs. And it can accurately determine fracture feature, permeability, as well as development of primary and secondary pores in carbonate reservoir. Meanwhile the application results of explanation are testified by well testing. This paper presents a study of explanation method and effectiveness of reservoir parameter of buried hill carbonate reservoirs in Lunnan reservoir of Tarim Basin, which overcome influence of horizontal detection depth and heterogeneity by combining conventional logging and imaging logging information. Through analysis on property of heterogeneity reservoir and fracture distribution, the accuracy of logging explanation in carbonate reservoirs is increased, finally resulting in correct evaluation on carbonate reservoirs.
