    Abstract
  • PF-MOSHIELD, a high temperature plugging agent, has been developed for use in oil base drilling fluids to enhance the efficiency of plugging fractures with wide size distribution at elevated temperatures in drilling high temperature high pressure wells complicated with developed beddings and microfractures. PF-MOSHIELD is made from a unique chemical modifier, sulfonated asphalt, acid soluble calcium carbonate, nanophase silica and styrene acrylate. PF-MOSHIELD, with its particle sizes distributed in the range of 1-189.02 μm, has good thermal stability; the decomposition temperature of PF-MOSHIELD is 378℃, and the softening point is 260℃. PF-MOSHIELD is dispersible in oil. Compared with conventional plugging agents for oil base drilling fluids, PFMOSHIELD can be squeezed into microfractures under pressure, taking part in the buildup of both the "inner filter cake" and the "surface mud cake". PF-MOSHIELD can, at high temperatures, plug fractures of different porosities, effectively reducing the amount of filtrate and the rate of filtration. Field application of PF-MOSHIELD on wells drilled in the Block WZ6-9 and Block WZ12-1 showed that drilling fluids treated with PF-MOSHIELD had stable rheology and enhanced electric stability, and pressure transferring in the pores in shale formations was weakened, all satisfying the needs of borehole wall stabilization in drilling hard brittle and fractured formations developed with beddings and microfractures.
