Abstract

The invention discloses an oil storage tank production metering and moisture content analysis method and device, which belong to measuring devices. A vertical screen pipe penetrates through the tank top from the tank bottom in the oil storage tank, a reflecting buoy is transversely arranged in the screen pipe, a data receiving processor is arranged at the top of the screen pipe, the lower end of the data receiving processor is connected with a laser distance measuring sensor, a laser head of the laser distance measuring sensor is perpendicular to the axial direction of the screen pipe, and a pressure sensor is arranged at the bottom of the tank and connected with the data receiving processor at the top through a wire. The measuring method comprises the following steps: the liquid level height H in the tank is measured through the laser range finder, the pressure intensity P of liquid in the tank is measured through the pressure sensor, the density Rhomixing=P / (H*g) of mixed liquid in the tank is obtained, the volume moisture content Q of the mixed liquid is obtained, and Q=(Rhomixing-Rhooil) / (Rhowater-Rhooil). The oil storage tank production metering and moisture content analysis device is reasonable in structural design, the liquid level height can be accurately measured through the laser distance measuring sensor and the reflecting buoy, and the measured moisture content andyield data are accurate and reliable.

Description

technical field [0001] The invention belongs to measuring devices, in particular to a method and device for measuring oil storage tank production and analyzing water content. Background technique [0002] In the process of oilfield production, the monitoring and analysis of oil well production (oil) and water cut is a basic basis for production operation management. In the production process, due to the lack of accurate automatic measurement means, the real situation of the front-line production status cannot be summarized in the hands of technical management and production decision-makers in time, resulting in some management blind spots. The patent with the publication number of Chinese document CN2765188Y discloses that it consists of a liquid level measuring element (1), a pressure measuring instrument (2, 3) and a data processing display (6). The liquid level measuring element (1) is placed in the oil storage tank On the liquid surface of the inner crude oil (5), the p...
