Detailed description of the invention
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existingHave the accompanying drawing of required use in technical description to be briefly described, apparently, the accompanying drawing in the following describes is only thisSome embodiment of invention, for those of ordinary skill in the art, not paying under the prerequisite of creative work, also canTo obtain other accompanying drawing according to these accompanying drawings.
Referring to Fig. 1, wet crude enters after settling tank, due to its density difference, is subject to Action of Gravity Field and is divided into from high to lowBe divided into successively low wet crude layer, emulsion layer and water layer. After wet crude layering, the porous media situation of each layer can be referring toFig. 2, in water layer, moisture content changes comparatively violently, and emulsion layer moisture content also exists comparatively significantly and to change, and along with the liter of heightHeight, because oil density is lower, is gathered in low wet crude layer, forms the stable region of moisture content, also not along with highly becomingChange, in this stability region, moisture content is probably between 3%～4%, and corresponding crude content is 96% to 97%.
Crude oil water content detection system of the present invention occupy following principle, in the stability region of low wet crude layer,Its moisture content is stable, can be using this moisture content as a preset value, and by calculating the close of wet crude in this regionDegree, with default substantially constant water density, can calculate the real-time density of this wet crude Crude Oil in real time, and then according toThe real-time density of this crude oil, the wet crude density that each is highly measured in settling tank is combined, and just can calculate settling tankWater content of interior each height.
