Abstract

The invention relates to a nano-magnetic-fluid-based hydraulic fracturing fracture real-time monitoring system and a nano-magnetic-fluid-based hydraulic fracturing fracture real-time monitoring method. The monitoring system comprises a proppant container, a fracturing fluid container, a magnetic fluid container, a fluid mixing container, a high-pressure pump set, a real-time data acquisition and processing center, a ground magnetometer, a proppant conveying pipeline, a fracturing fluid conveying pipeline, a magnetic fluid conveying pipeline, a first sand blending liquid conveying pipeline, a second sand blending liquid conveying pipeline, a ground magnetometer and real-time data acquisition and processing center communication line, a fracturing blender truck and a mixed fluid conveying pipeline; wherein the real-time data acquisition and processing center is connected with the ground magnetometer through the ground magnetometer and real-time data acquisition and processing center communication line; and the real-time data acquisition and processing center collects and saves metrical information of the ground magnetometer, and computes and displays hydraulic fracture distribution. The nano-magnetic-fluid-based hydraulic fracturing fracture real-time monitoring system and the nano-magnetic-fluid-based hydraulic fracturing fracture real-time monitoring method can reflect the real distribution state of hydraulic fracturing fractures effectively and monitor the extension process of the fractures during a fracturing process from the ground, a fracturing well and / or an adjoining well.

Description

technical field [0001] The invention belongs to the fields of petroleum and natural gas, coal bed methane and geothermal development, and in particular relates to a system and method for monitoring hydraulic fracturing fractures, in particular to a real-time monitoring system and method for hydraulic fracturing fractures based on nano-magnetic fluid. Background technique [0002] As an important measure to improve reservoir permeability and increase production capacity, hydraulic fracturing technology has been widely used in oil and gas, coalbed methane, and geothermal exploitation. Especially with the exploitation of unconventional oil and gas and geothermal energy, hydraulic fracturing technology will become more and more important. [0003] In the process of hydraulic fracturing, monitoring the occurrence and development of hydraulic fractures is of great significance to optimize the construction process; and for refracturing wells and multi-stage fracturing wells, master...
