Abstract
ABSTRACTCementing is a very important part in oil-well drilling, the recent technologies development in oil-well drilling has led to a more problematic case in cementing. High temperature cementing is one of those problem, high temperature cementing consists of steam recovery wells, geothermal wells and ultra deep wells.The use o f expanding cements for improving the sealing efficacy o f Annulus cementing has been considered for a long time as a possible solution to existing problems. CaO and MgO had been proposed as two o f the most effective additives to create good expanding cement.The purposes o f this study are to find the effect o f burnt pure CaO and MgO addition on the value o f compressive strength and shear bond strength o f API class G in high pressure and high temperature condition. The method applied on this research was by evaluating the data taken from simulator which was simulate with 100-250°C temperature and 2000 psi pressure.The conclusions taken according to the results are: The addition of CaO and MgO will increase the shear bond strength and the compressive strength on specific condition up to 200°C temperature. The addition will be ineffective for the 250°C condition. The cement strength behavior will be also affected by the length o f curing time.This expanding cement needs some further research for other composition, temperature and curing time condition. The compatibility when mixed with other additives beside silica flour hasn’t been figured out y et Keywords: Expanding Additive, Shear Bond Strength, Compressive Strength, High Pressure-High Temperature, Curing Time
