Beschreibung
Zusammenfassung:	The utility model provides a pressure-controlled switch control series connection type underground oil-water interface detecting system. The pressure-controlled switch control series connection type underground oil-water interface detecting system comprises a ground detector and an oil-water interface detecting sensor group which is connected with the ground detector through an armored cable. The oil-water interface detecting sensor group is composed of four oil-water interface detecting sensors. The pressure-controlled switch control series connection type underground oil-water interface detecting system which is composed of the four oil-water interface detecting sensors and the ground detector can be used for measuring an underground oil-water interface, so that continuous measurement of the underground oil-water interface is achieved, the detecting depth range of the underground oil-water interface is widened, the measurement accuracy of the underground oil-water interface is improved, the lifting frequency of a cavity construction outer tube is reduced, the cavity construction cost is lowered, and the measuring requirement for the underground oil-water interface of a novel cavity construction engineering technology in reverse circulation cavity construction can be met.
