摘要:
准噶尔盆地吉木萨尔凹陷二叠系芦草沟组是中国陆相非常规油气勘探的重要目标,为精细描述和预测陆相致密储集层致密化进程差异、明确甜点体发育模式,以吉木萨尔凹陷芦草沟组致密储集层为例,利用铸体薄片、扫描电镜、物性测试、碳氧稳定同位素测试和包裹体均一温度测试等实验方法,分析了芦草沟组封闭型成岩系统内部成岩作用的相互影响,揭示了储集层不同致密化路径,明确了甜点体储集层的发育机理。研究表明,根据成岩演化路径,芦草沟组存在4种致密化模式,分别为碳酸盐岩弱溶蚀致密、富塑性岩屑强压实致密、正常压实方解石强胶结致密和碳酸盐矿物胶结+黏土矿物胶结耦合叠加致密。相应划分出3种甜点体形成机制,分别为局部超压与早期绿泥石协同保存原生孔隙模式、第1期强溶蚀增孔和2期溶蚀叠加增孔,这3种甜点体发育模式更易形成于厚层砂质滩坝和三角洲远砂坝等陆源碎屑含量较高的优势沉积微相中。
Abstract:
The tight oil in Permian Lucaogou formation of Jimsar sag is the important target for terrestrial unconventional oil and gas exploration in China. In order to describe and predict the difference in densification process of terrestrial tight reservoirs, and to define the development model of the sweet spots, the paper takes the tight reservoir of the Permian Lucaogou formation in Junggar basin as an example to analyze the interaction of diagenesis within the closed diagenetic system of the Lucaogou formation, reveals various reservoir densification paths and clarifies the development mechanism of sweet spot based on the data of thin section, SEM, physical property, stable carbon and oxygen isotopes analysis and fluid inclusion homogenization temperature. The research indicates that according to their diagenesis evolution paths,four densification types of the tight reservoirs in Lucaogou formation are summarized such as weak dissolution of carbonate rock, strong compaction of plastic debris, normal compaction and strong calcite cementation, and carbonate cementation + clay mineral cementation and superposition. Three forming mechanisms of sweet spots are classified including primary pore preservation of local overpressure and early chlorite protection, one period of strong dissolution and superposition of two-period dissolution. These three types of sweet spots are more likely formed in the dominant sedimentary microfacies with high terrigenous clastics content such as thick sandy beach bars and distal bars in deltas
