Differential pressure device capable of measuring and adjusting pressure and viscosity in real time and measuring method thereof

Abstract

The invention relates to a differential pressure device capable of measuring and adjusting pressure and viscosity in real time and a measuring method thereof, wherein the differential pressure devicecapable of measuring and adjusting the pressure and viscosity in real time comprises an outer barrel and adjustable annular throttling troughs. The adjustable annular throttling troughs are installedon the inner wall of the outer barrel perpendicularly sequentially at equal intervals and are in a split type. A throttling trough single body is in an arc shape, and four throttling trough single bodies are arranged on one peripheral face concentrically in a two-two-adjacent mode to form one adjustable annular throttling trough. A viscosity meter is installed on the surface of an arc-shaped innerplate of the last adjustable annular throttling trough. The viscosity meter is connected with an induction plate through a transmission line. A pressure sensor and a torque sensor are installed on the arc-shaped inner plate of the last adjustable annular throttling trough and are both connected with the induction plate. The induction plate is connected with a DSP control module. Throttling differential pressure is changed by changing the annular throttling troughs of the differential pressure device, pressure of solution is adjusted, and meanwhile viscosity of the solution can also be changed.

Description

Technical field: [0001] The present invention relates to a partial pressure injection device used in stratified injection during oilfield development and production, in particular to a partial pressure device and a measuring method thereof which can measure and adjust pressure and viscosity in real time. Background technique: [0002] The main application objects of polymer flooding and other chemical flooding technologies mostly have problems such as strong heterogeneity of oil layers, many layers, and large differences between layers. The production degree of the low-permeability layer is low, which reduces the overall oil displacement effect. The layered injection process can alleviate the contradiction between layers, improve the injection profile, and improve the overall development effect. To achieve the above effects, it mainly depends on the throttling element in the partial pressure injection tool. Traditional throttling elements mainly include annular pressure-re...
