Device and method for testing proppant laying of API flow guiding chamber

Abstract

The invention relates to the field of petroleum engineering and discloses a device and method for testing the proppant laying of an API flow guiding chamber. A signal generator is connected to a probe, the probe is arranged at an outlet end of the flow guiding chamber, and a silicone film is arranged in the flow guiding chamber and is used for wrapping a proppant. Parts of the proppant facing theoutlet end and an inlet end of the flow guiding chamber are exposed, and a signal emitting end of the probe faces an exposed side of the proppant. A piezoelectric sensor is arranged at an inlet end ofthe flow guiding chamber and faces the other exposed side of the proppant, and the piezoelectric sensor is connected to a data analysis and processing device and is used for receiving a vibration signal and transmitting the vibration signal to the data analysis and processing device, and the data analysis and processing device is used for receiving the signal of the piezoelectric sensor and drawing a time domain map by using the signal. Whether the laying of the proppant is uniform can be judged by using the time domain map. The method of the invention has the advantages of simple principle and easy implementation, the laying of the proppant can be accurately judged, and more accurate and effective experimental data is obtained.

Description

technical field [0001] The invention relates to the field of petroleum engineering, in particular to a laboratory device applied to a proppant fracture conductivity evaluation system, in particular to a device and a test method for testing the proppant laying of an API diversion chamber. Background technique [0002] In the stimulation measures of oil and gas fields, whether fractures with high conductivity can be formed is the key to fracturing operations. The conductivity of fractures directly affects the production of oil and gas fields. In different oil reservoirs, the conductivity of fractures under different conditions has a great impact on stimulation. have different effects. In order for the reservoir to be able to produce stably after fracturing, it is necessary to understand the conductivity of the proppant fractures and the various factors that affect the conductivity of the fractures. This requires the analysis of the obtained data by means of experiments. Adjus...

Problems solved by technology

Since the instrument requires the filled proppant packing layer to be in a uniform state, but the experiment usually judges whether the proppant packing layer is uniform based on the subjective experience of the experimental researchers, there is a certain assumption, but if the packing layer is not uniform, it will lead to the measured The error of the experimental data is so large that it cannot be used to affect the experimental results

Judging from the existing laboratory methods, there is no improved device or experimental method for this situation.
