Development and Performance Evaluation of hydrophobic nano-silica enhanced foam drainage agent
摘要
Abstract
The bottom hole fluid accumulation in the middle and late stage of shale gas well production is the main reason leading to the decrease of productivity.The stability of foam drainage agent has become the key technology to solve the problem of bottom hole fluid accumulation.The hydrophobic nano-silica has unique surface effect,which can enhance the foam stability.In this study,the modified Ross-Miles method,the Waring Blender method and the Air-flow method were used to optimize the six foaming agents and six foam stabilizing agents.At the same time,the polymer foam stabilizing agent CC-1 and the hydrophobic nano-silica T-SiO2 were combined.The foaming agent system of hydrophobic nano-silica was prepared.The optimum formula of foam discharging agent was confirmed as follows:0.375％AS-1+0.125％802+0.3％CC-1+0.5％T-SiO2.Through the evaluation of temperature resistance,salinity resistance,oil resistance,methanol resistance and liquid carrying performance of the foam drainage agent,the results showed that the foam drainage agent could resist 120 ℃,resist 10×104mg/L salinity,and the antibody integral number was 20％diesel and 20％methanol,and the liquid carrying rate reaches 61％when the mass fraction was 0.5％.关键词
