[Abstract]:In the process of actual exploration and development of deep volcanic rock reservoir in Yingtai fault depression in Wangfu in the south of Songliao Basin, some problems have been encountered which hinder the fine exploration and development of volcanic oil and gas. For example, there are few studies on the distribution and formation mechanism of neutral volcanic rocks and sedimentary clastic reservoirs. 2) the current criteria for classification and evaluation of volcanic reservoirs are too general, lack of criteria for different lithology, and lack of constraints of reservoir pore structure parameters. In this paper, the neutral volcanic rocks of Huoshiling formation in Wangfu fault depression in the south of Songliao Basin and the sedimentary pyroclastic rocks of Ying2 member of Yingtai fault depression in Yingtai fault depression are taken as research objects. The data of core, thin slice, analysis and test, well logging and earthquake are used synthetically. The pore characteristics of two types of volcanic reservoirs are studied and the controlling factors and genesis of the reservoirs are discussed. The criteria for the classification and evaluation of volcanic reservoirs with different lithology based on the constraints of qualitative and quantitative characterization of reservoir pore structure are preliminarily established. This paper aims at the neutral volcanic rocks of Huoshiling formation in Wangfu fault depression in the south of Songliao Basin. Starting from the relationship between lithology, lithofacies, buried depth, volcanic mechanism and interface between volcanic strata and reservoir, the reservoir development law is analyzed. The neutral volcanic lava is taken as an example. The reservoir control effect and reservoir control mechanism of volcanic strata interface are discussed, and the favorable exploration targets are pointed out. In view of the sedimentary pyroclastic rocks in the second member of Yingcheng formation of Yingtai fault depression in southern Songliao Basin, the origin of abnormal high porosity and permeability zone of deep submersed pyroclastic rocks in the basin is revealed from various angles. It is pointed out that the dissolution in diagenesis is its main controlling factor. It is based on the qualitative and quantitative characterization of pore structure and its comparison with specific gas recovery index. Based on the cluster analysis of reservoir physical properties of 388 sets of samples and 8 parameters in 35 wells, the lower limit of effective reservoir physical properties is determined, and the effective reservoir classification and evaluation criteria for different lithology are given.
