Abstract

Abstract

Oil based drilling fluids are now more and more used in the continuous development of oil and gas resources because of their excellent performance. Wells drilled with oil based drilling fluids have their borehole wall oil wetted, and this inevitably affects the cementing quality of the cement slurries. One way of dealing with this problem is to use flushing fluid to clean the oil based drilling fluids adhered on the borehole walls, hence turning the borehole wall to water wet. A high water content (≥ 80%) microemulsion flushing fluid was developed with raw materials such as EAB-40, SDBS, n-butanol, kerosene and water. The microemulsion flushing fluid was evaluated of its bubble rate, flushing capacity and ability to reverse the wettability of the borehole walls. The microemulsion was then made into a spacer, and flushing with the spacer fluid was done to investigate the flushing performance of the spacer and the compatibility of the spacer with cement slurries and oil based drilling fluids. The experimental results show that the microemulsion flushing fluid has a bubble rate of 17.07%, a flushing efficiency of at least 99%, and has excellent wettability reversal ability. The spacer made from the microemulsion flushing fluid has a flushing efficiency of at least 99%, and has good compatibility with cement slurries and oil based drilling fluids. As a result, this study has produced a high efficiency, low bubble rate, high water content microemulsion flushing fluid with good compatibility.
