Embodiment Construction

[0035] In the process of measuring the performance of permeable stone cement slurry, the following methods are used:

[0036] (1) Experimental slurry preparation, STS-1 slurry preparation, add 45 parts by volume of distilled water into the container, add 100 parts of aluminophosphate cement, stir well and set aside; STS-1 liquid preparation, add volume parts into distilled water in the container 50 backups;

[0037] (2) The basic performance test of STS-1 slurry, measuring the density, viscosity, fluidity, water loss, free water content, initial setting time, final setting time and compressive strength of STS-1 slurry at 25°C and normal pressure, And make records; measure the density, viscosity, fluidity, water loss, free water content, initial setting time, final setting time, compressive strength of STS-1 slurry at 50°C and normal pressure, and make records. The environmental conditions of different reservoirs are different, so the adjustment of temperature is to simulate t...

Abstract

The invention discloses a device and a method for measuring permeable stone cement paste for fracturing and belongs to the technical field of energy sources. Through the method, stratum conditions areaccurately simulated to measure important parameters like density, viscosity, fluidity, water loss, free water content, initial setting time, final setting time, compressive strength, permeability, porosity and degree of damage to reservoirs, data are integrated for accurate analysis, and characteristics of the cement paste in a rock stratum are objectively reflected, so that the method is of important significance in stratum energy development. Through the device, experiment operation is convenient, and more accurate experiment data are collected.

Description

technical field [0001] The invention belongs to the field of energy technology, and in particular relates to the research on the method for measuring the performance of permeable rock cement slurry for fracturing reconstruction of tight oil and gas field reservoirs, specifically a device and method for measuring the performance of permeable rock cement slurry for fracturing. Background technique [0002] Tight oil and gas reservoirs are unconventional oil and gas reservoirs with huge development potential. At present, hydraulic fracturing is mainly used to transform tight reservoirs and develop tight oil reservoirs. However, hydraulic fracturing has the advantages of large construction scale and high construction pressure. , Large consumption of manpower, material resources and water resources, great hazards to the reservoir, serious pollution of the environment by the flowback liquid, etc. [0003] Osmotic stone is to use high-density cement slurry instead of conventional f...
