The tight reservoirs of the Fengcheng Formation at the southern margin of the Mahu Sag have strong heterogeneity due to the diversity in their pore types, sizes, and structures. The microscopic characteristics of tight reservoirs and the mechanisms that generate them are of significance in identifying the distribution of high-quality reservoirs and in improving the prediction accuracy of sweet spots in tight oil reservoirs. In this paper, high-pressure mercury intrusion (HPMI) and nuclear magnetic resonance (NMR) experiments were carried out on samples from the tight reservoirs in the study area. These experimental results were combined with cluster analysis, fractal theory, and microscopic observations to qualitatively and quantitatively evaluate pore types, sizes, and structures. A classification scheme was established that divides the reservoir into four types, ba.ed on the microstructure characteristics of samples, and the genetic mechanisms that aided the development of reservoir microstructure were analyzed. The results show that the lower limit for the tight reservoir in the Fengcheng Formation is Φ of 3.5% and K of 0.03 mD. The pore throat size and distribution span gradually decrease from Type I, through Type II and Type III reservoirs to non-reservoirs, and the pore type also evolves from dominantly intergranular pores to intercrystalline pores. The structural trend shows a decrease in the ba.l-stick pore-throat system and an increase in the branch-like pore-throat system. The dual effects of sedimentation and diagenesis shape the microscopic characteristics of pores and throats. The sorting, roundness, and particle size of the original sediments determine the original physical properties of the reservoir. The diagenetic environment of ‘two alkalinity stages and one acidity stage’ influenced the evolution of pore type and size. Although the cementation of authigenic minerals in the early alkaline environment adversely affected reservoir properties, it also

以胜坨油田二区沙二段34层为例,研究不同储层构型要素组合对剩余油分布的影响,为深入研究构型要素控制剩余油分布规律奠定了基础.通过对7口取心井的观察和分析,利用密井网条件下丰富的测井资料,划分出7种构型要素.其中心滩、河道充填沉积为好的构型要素,其余的为差构型要素;空间上,将构型要素分为6种不同组合形态,即:好-好-好型;好-好-差型;好-差-好型;好-差-差型;差-好-差型;差-差-差型.研究认为,构型要素空间组合影响剩余油的分布和富集效果.剩余油主要富集于差构型要素内部、好构型要素与差构型要素交界处及好构型要素内部渗流性能较差处.

通过对新北油田油气层、油水同层及水层围岩的电阻率特性分析,认为该区电阻率差异较大,既存在正常油气层的电阻率特征,又存在低阻油气藏的电阻率特征。研究总结有如下规律:该区油气层束缚水饱和度越高,电阻率越低;油层厚度越薄,电阻率越低;构造幅度越小,电阻率越低;地层水矿化度越大,电阻率越低;油水系统越复杂,电阻率越低;原油性质好,钻井液侵入后的油层电阻率相对较低。最后,从油气藏成因角度总结出,该区低阻油气层形成的最根本原因是受到区域的构造背景、沉积环境成藏过程等控制。对于此类油层的认识,要综合考虑以上各种因素,建立相关的解释模型才能进行准确判断和识别。
