Problems solved by technology

[0003] However, in the existing studies, the dynamical system and fluid migration mechanism are not clear, and the coupling control mechanism between the dynamical system of accumulation and the elements of accumulation is unclear. There is no in-depth research and exploration on oil and gas exploration based on the dynamical system of accumulation, and there is no basis. Research on the actual geological characteristics of different exploration areas to establish oil and gas accumulation models under the control of different dynamic systems, and then predict oil and gas enrichment areas

Abstract

The invention discloses a method and system for predicting an oil and gas enrichment area based on potential energy values and physical property values. The method comprises the steps: according to drilling data, the potential energy values and the physical property values of all measuring points in a region are calculated; the potential energy values and the physical property values of all the measuring points and the corresponding oil bearing saturation of all the measuring points are calculated, and the facies-potential reservoir controlling function relationship is obtained; and accordingto the facies-potential reservoir controlling function relationship, the oil and gas enrichment area in the region is predicted. According to the drilling data and laboratory measurement data, geological features in the exploration region are comprehensively analyzed, a typical oil and gas reservoir is analyzed, the relationship between a power system and of oil and gas distribution is determined,the oil and gas enrichment area in the region is predicted, and oil and gas exploitation is facilitated.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration, in particular to a method and system for predicting oil and gas enrichment areas based on potential energy values ​​and physical property values. Background technique [0002] The concept of petroleum system applied in my country is proposed for foreign sedimentary basin type models, but the object of sedimentary basins is too different from that of continental sedimentary basins in my country, especially for complex compressive torsional superimposed basins in western my country, with multiple oil sources and multiple Due to geological conditions such as early structural superimposition and complex conduction systems, using the "four Figure 1 It is difficult to explain the process of oil and gas accumulation, and there is even less scientific and reliable basis for oil and gas prediction. Facing the situation that geological conditions are becoming more and more complex and oil an...
