Abstract

Satu penipis lumpur gerudi yang diperbaiki iaitu kompleks stanum–tanin–lignosulfonat, telah dihasilkan dengan melakukan pengubahsuaian terhadap penipis komersil iaitu lignosulfonat. Tindak balas yang terlibat termasuk tindak balas rangkai silang antara asid lignosulfonat dengan tanin pada suhu 105°C dengan kehadiran formaldehid yang berfungsi sebagai pemula tindak balas tersebut. Campuran tersebut selanjutnya dikelatkan dengan ion stanum. Tindak balas pengubahsuaian tersebut ditentusahkan menerusi analisis spektroskopi inframerah (IR) dan prestasinya sebagai agen penipis berpolimer bagi lumpur bentonit akueus dinilai. Prestasi reologi penipis terubahsuai tersebut kemudiannya dibandingkan dengan lignosulfonat. Keputusan menunjukkan bahawa penipis terubahsuai mempunyai prestasi penipisan yang lebih baik berbanding lignosulfonat pada suhu tinggi dan juga ketahanan yang lebih tinggi terhadap pencemaran garam. Kata kunci: lignosulfonat; bendalir/lumpur gerudi;ion stanum; tannin; prestasi reologi An improved drilling fluid thinner, tin–tannin–lignosulfonate (TTLS) complex; was formulated by imposing slight modifications to a commercially available thinner, lignosulfonate. The reactions involved include reaction of a lignosulfonate acid with tannin at 105°C in the presence of formaldehyde to initiate the cross-linking reaction. The mixture was further chelating with stannous ions. The modifications reactions were verified by an infrared (IR) spectroscopy analysis and its performances as a polymeric thinning agent for aqueous bentonite mud were evaluated. The rheological performances of the modified thinner were then compared with lignosulfonate. The modified thinner shows better thinning performance at higher temperature and indicates more tolerance to salt contamination compared to lignosulfonate. Key words: lignosulfonate; drilling fluid/mud; thinner; stannousion; tannin; rheological perfomances
