Fiscal 1980 Sunshine Project research report. Development of slurry applicable to geothermal environment; 1980 nendo chinetsu kankyoka de shiyo kanona deisui no kaihatsu seika hokokusho

Abstract

This report summarizes the fiscal 1980 research result on development of slurry applicable to geothermal environment. Study was made on the hydrothermal alteration and rheology of the clay suspension slurry system composed of base mud of sepiolite (thermogel), dehydrator of sodium polyacrylate (SPA), and dispersant GT-8. The study result clarified roughly the action mechanism of such slurry under geothermal environment. Such slurry thus achieved an expected target experimentally through various tests on slurry characteristics at higher temperature, slurry curing and slurry conditioning. Test was made on the lubricity of air system drilling fluid. Simulated field test was made on a preventive effect from lost circulation by using combination of various materials. The preventive effect increased with the kind of additional preventive agents. As for waste sludge treatment technology, the agitating capacity of a mixing tank for polymer flocculant was improved. Study was made on possible continuous treatment of sludge by using the above equipment and a continuous sludge caking equipment, resulting in achievement of an expected target. (NEDO)
