Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention will be further described:

[0030] to combine Figure 1-Figure 9 As shown, the spiral pressure divider that can measure and adjust the pressure in real time includes an outer cylinder 1, an inner cylinder 2, a spiral throttle groove 3, a pressure sensor 11, a computer, an outer cylinder 1 and an inner cylinder 2 are coaxially arranged, and the inner cylinder 2 The two ends are provided with inlet 16 and outlet 17 respectively. The spiral throttling groove 3 is installed on the wall surface of the inner cylinder 2. Between the inner cylinder 2 and installed on the inner wall of the outer cylinder 1; the telescopic spiral groove is made of a telescopic spiral stripe plate 5, and the cross section is trapezoidal. The telescopic spiral groove is formed by telescopically connecting together a section of the trough along the spiral direction. The first section of the section of the trough is closed at the...

Abstract

The invention relates to a spiral pressure divider with real-time measurement and adjustment of pressure and its measurement method, wherein the spiral pressure divider with real-time measurement and adjustment of pressure includes an outer cylinder, an inner cylinder, a spiral throttle groove, and a spiral throttle groove installed On the wall of the inner cylinder, the spiral throttling groove includes a telescopic spiral groove, a spiral slideway, and a roller, and the spiral slideway is installed between the outer cylinder and the inner cylinder on the inner wall of the outer cylinder; The tank body is telescopically connected together along the spiral direction, and the tank top is installed on the outer wall of the inner cylinder. The roller bearing is installed on the outside of the tank top, and the roller is located in the spiral slideway. The control handle is fixed outside the tank top, and the control handle passes through. The outer cylinder is equipped with a knob, the contact surface of the spiral slideway and the outer cylinder is equipped with a scale plate with a scale, the pressure sensor is installed near the outlet of the inner cylinder, and the sensor chip is connected to the controller. The invention solves the technical problem that the traditional pressure dividing device cannot change the mechanical structure to change the different throttling pressure differences of the solution.

Description

Technical field: [0001] The present invention relates to a partial pressure injection device used in stratified injection during oil field development and production, and in particular to a spiral pressure partial pressure device and a measuring method thereof, whose pressure can be measured and adjusted in real time. Background technique: [0002] In the process of oilfield polymer flooding development, polymer flooding can improve the injection profile to a certain extent, but due to the influence of various factors such as reservoir heterogeneity and well pattern perfection, the contradiction between layers has not been fundamentally resolved. solve. Under the general injection method, the contradiction between good oil layers and poor oil layers is more prominent. Thick oil layers with high permeability and well-developed oil layers have high producing degree; while oil layers with low permeability and poorly developed oil layers have low producing degree. Since the po...
