Engineering, Southwest Petroleum University, Xindu, Chengdu China Received: 1 July
2015/Accepted: 1 March 2016 ABSTRACT The main objective of this
work was to investigate the influence of waterborne epoxy resin
emulsion (WER)
on the physical properties of oil well cement slurries. Cement
slurries containing 5%, 10% and 15% of WER bwoc were compared with WER-free
slurries. The rheological behavior was carried out according
to API standard.
Uniaxial compressive strength and shear bond strength of cement
stone were evaluated at the ages of 24, 48 and 72 h. The experimental
results illustrate that the addition of WER does not alter the rheological behavior.
The addition of WER has increased the shear bond strength
almost 52% at 24 h of aging for 10% WER bwoc
when compared with unmodified slurry. The enhancement on shear
bond strength was attributed to the mechanical anchoring and
resin film forming at the interface. Keywords: Mechanical properties;
oil well cement; rheological properties; waterborne epoxy resin

ini adalah untuk mengkaji pengaruh emulsi resin epoksi bawaan
air (WER)
ke atas sifat fizikal sluri simen telaga minyak. Sluri simen
yang mengandungi 5%, 10% dan 15% WER bwoc dibandingkan dengan sluri tanpa
WER. Tingkah laku reologi telah dijalankan mengikut piawai
API. Kekuatan mampatan unipaksi dan kekuatan ikatan ricih
batu simen telah dinilai pada umur 24, 48 dan 72 jam. Keputusan
kajian menunjukkan bahawa penambahan WER tidak mengubah tingkah laku
reologi. Penambahan WER telah meningkatkan kekuatan ikatan
ricih hampir 52% pada umur 24 jam untuk 10% WER bwoc
apabila dibandingkan dengan sluri tidak diubah suai. Peningkatan
pada kekuatan ikatan ricih adalah disebabkan oleh yang tambatan
mekanik dan resin filem yang membentuk di antara muka. Kata kunci: Emulsi resin epoksi bawaan air; sifat mekanik; sifat
