Problems solved by technology

[0004] However, the brittleness data obtained by the above methods cannot accurately reflect the complexity of the fracture network formed when the volcanic oil and gas reservoirs are fractured. Therefore, it is impossible to take targeted construction measures for the reservoirs. Therefore, the development effect is not good, and the oil and gas low output

Abstract

The invention provides a volcanic rock oil and gas reservoir development method and a volcanic rock compressibility obtaining device, and belongs to the technical field of oil and gas field development. According to the technical scheme provided by the embodiment of the invention, the rock core of each layer section in the oil and gas reservoir is obtained, the pressure and temperature conditions of the stratum where the rock core is located are simulated, then the rock core is fractured, and the initial permeability and the fractured permeability of each rock core are obtained respectively; and the compressibility can reflect the complexity of forming a fracture network after the rock core is fractured, so that development measures are selected for different layer sections according to the compressibility, the layer sections with good compressibility can be preferentially selected for exploitation, and the exploitation efficiency is improved. And construction measures suitable for different layer sections can be formulated for the layer sections, so that the oil and gas yield of volcanic rocks is increased.

Description

technical field [0001] The present application relates to the technical field of oil and gas field development, in particular to a method for developing volcanic rock oil and gas reservoirs and a device for obtaining compressibility of volcanic rock. Background technique [0002] Volcanic rock oil and gas reservoirs are widely distributed on five continents, mainly on the boundaries of tectonic plates. The lithology of developed volcanic rock gas reservoirs is mainly volcanic lava, including basalt, andesite, rhyolite, pyroclastic rock, etc. The economical and effective development of volcanic rock oil and gas reservoirs must carry out oil and gas stimulation measures. It is an important indicator of the difficulty of reservoir fracturing and the quality of fracturing effect. Pyroclastic rocks are very different from other volcanic rock lithologies, conventional sandstones, carbonate rocks and other oil and gas reservoirs. The main performance is that pyroclastic rocks hav...
