Experimental study on the injection of polysilicon nanomaterials in natural gas pipeline

Abstract

China is a big oil country, and its oil production and storage are in the forefront of the world. However, China's oil resources are mainly low-permeability reservoirs. It is characterized by small porosity, which leads to the increase of injection pressure and seriously affects the production rate. The main solution is to use polysilicon nano injection enhancer. Polysilicon nano materials can solve the problem of high injection pressure from the micro level. At present, there are many researches on polysilicon nano injection technology at home and abroad, but the research on the application of polysilicon nano materials in natural gas pipeline materials is still blank. In order to solve this problem, this paper will further study the injection enhancement effect of polysilicon nano materials in natural gas pipeline materials. First of all, through theoretical research and analysis, this paper believes that polysilicon nano injection technology has good application, good effect in oilfield injection pressure drop, and obvious advantages over other traditional injection additives. In order to further analyze the injection enhancement effect of polysilicon nanomaterials, the corresponding experimental model is established. The experiment is divided into two parts, one is the preparation of reagents and solvents. In this paper, nano polysilicon solution and corrosion inhibitor are re optimized. The other part is the specific test steps. In order to ensure the quality and verifiability of the test, this paper explains and records the test principle and steps in detail. After sampling and analysis of many core factors such as adsorption time and permeability, it can be seen from the analysis data that when polysilicon nanomaterials are injected, when the injection volume is about 1pv, the effect of depressurization is the best, and the comprehensive effect of depressurization is good. This study has achieved ideal results, which is of great significance to the related research of oil field.
