Abstract

The invention discloses a microearthquake positioning method and a system and belongs to the geological exploration technology field. A location of earthquake can be rapidly and accurately positioned and microearthquake monitoring and research efficiency is increased. The microearthquake positioning system comprises a plurality of subsystems. Any subsystem comprises a processing unit and a plurality of acquisition units. The plurality of acquisition units are connected to the processing unit and are distributed around the processing unit. Each acquisition unit is used for collecting microearthquake first arrival time and sending to the processing unit. The processing unit is used for processing microearthquake generation locations acquired from each first arrival time after receiving the first arrival time of each acquisition unit.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a microseismic positioning method and system. Background technique [0002] Microseismic monitoring technology is an important technology developed rapidly in recent years to solve the development of low permeability oil and gas reservoirs. With the further emphasis on and demand for energy development, microseismic monitoring and research play a vital role in the development of unconventional oil and gas reservoirs such as tight sandstone and shale. Microseismic technology is to describe the fractures in the fracturing process by analyzing the microseismic signals received by the geophones in the adjacent wells from the fracturing wells during the fracturing process (currently mainly referring to the microseismic first-arrival travel time). Geometric distribution of growth and fluid migration characteristics (eg, fracture height, length, and orientation). This i...
