陜北大牛地氣田馬五段古巖溶儲(chǔ)層特征及控制因素
[Abstract]:Daniudi gas field is located in the central and eastern part of Ordos Basin with an area of about 3400 square kilometers. The lower Paleozoic karst weathering crust reservoir (Mawu1-Ma Wu 5 submember of Majiagou formation) is the focus of this paper. Based on the analysis of geological background, core, thin slice, logging, capillary pressure curve and other data, the characteristics and controlling factors of paleokarst reservoir of Ordovician Majiagou formation in Daniudi gas field are analyzed and studied in this paper. The main rock types of paleokarst reservoir in the study area are karst breccia and micro-powdery dolomite, followed by limestone, by analyzing the petrological characteristics, pore structure, physical properties and reservoir distribution of the reservoir. The types of pore structure in the study area are divided into four types, and the correlation between porosity and permeability in Daniudi gas field is poor. The paleokarst geomorphology is restored by the impression method and the residual thickness, and the advantages and disadvantages are compared. Finally, the paleokarst geomorphology is restored by the comprehensive analysis method, and the paleokarst geomorphology unit is divided. The reservoir characteristics, diagenetic environment, diagenesis, tectonism and the effect of sedimentation on paleokarst reservoir are analyzed in detail. Finally, it is concluded that the favorable areas for reservoir development in the study area are as follows: Da-48- Da-38 well area, Da-88-Da 29-Da-84 well area. Big 40-big 41-big 42 well area.
