Multifunctional physical model test device of horizontal well

Abstract

The invention relates to a multifunctional physical model test device of a horizontal well, comprising a main body, a real-time monitoring system, a power system, a data acquisition system and a sand production on-line monitoring system. The multifunctional physical model test device is characterized in that the main body is in a horizontal combined structure, is respectively and electrically connected with the real-time monitoring system, the data acquisition system and the and production on-line monitoring system and is controlled by the real-time monitoring system, the data acquisition system and the and production on-line monitoring system; the main body is connected with the power system through a pipeline; the power system comprises a plunger pump and a shunt tube connected with a stratum set box; the main body comprises a bracket and an outer sleeve installed on the bracket; the outer sleeve is internally provided with a sand filtering tube and a camera; and the stratum set box, a pressure sensor, a flowmeter and a sand content sensor are installed on the outer sleeve. The invention has the characteristics of more detection items, accurate data acquisition, convenient and fast operation, high automatization degree, visible operation, dynamic detection, good timeliness and the like, and is widely applied to sand prevention process of petroleum extraction.

Description

1. Technical field [0001] The invention relates to a sand control testing facility for horizontal wells in oil exploitation, in particular to a multifunctional physical model test device for horizontal wells. 2. Background technology [0002] At present, the understanding of the basic laws of sand production, thermal action, and seepage field in horizontal wells in oil exploitation is not yet clear enough, and the evaluation of its sand control technology has not yet been carried out. Regularity, screen blockage cleaning, etc. can only be done by feeling the stones and looking at it while doing it, which is very blind. Therefore, the comprehensive effect evaluation research of the above process technology and sand control optimization design is a problem that needs to be solved at present. . 3. Contents of the invention [0003] The object of the present invention is to provide an improved horizontal well multi-functional physical model test device, which adopts automatic...
