A black positive serosity (BPS) with organic active substances is recently developed. It is oil-soluble, water-wetting and shale inhibitory. Its positive charge (+70 mV) is twice as high as for MMH. The shale inhibiting capacity of 3% BPS solution is higher than that of 10% KCl solution. BPS is well compatible with other drilling fluid additives. 3 commercial filtrate reducers (LS-3, SJ-1, and TPOS-88) and 1 thinner( OSAM-K) having filtrate reducing, anti-caving and shale inhibiting functions are selected and...

A black positive serosity (BPS) with organic active substances is recently developed. It is oil-soluble, water-wetting and shale inhibitory. Its positive charge (+70 mV) is twice as high as for MMH. The shale inhibiting capacity of 3% BPS solution is higher than that of 10% KCl solution. BPS is well compatible with other drilling fluid additives. 3 commercial filtrate reducers (LS-3, SJ-1, and TPOS-88) and 1 thinner( OSAM-K) having filtrate reducing, anti-caving and shale inhibiting functions are selected and an excellent BPS fluid is formulated: 4% bentonite+1-3%BPS+1-3% filtrate reducer+1-3% viscosity controller+0.1-0.3% shale inhibitor. A typical fluid maintains its properties practically unchanged after ageing at 160℃ in 16 hrs and is highly lolerant to NaCl. On oil sand packs of different permeability, a sintered quartz, and 3 formation cores, the temporarily plugging and shielding by some BPS drilling/completion fluids together with 2 other fluids and the permeability recovery after kerosene injection are investigated, the appropriate plugging/shielding agents are found and the good protection of reservoir formations by a BPS fluid is ascertained. The successfull uses of BPS drilling/completion fluids in a lot of horizontal and directional wells in Shengli, Zhongyuan, and Jidong are described in some detail. The results of formation protection by using BPS fluids are analysed and it is concluded that BPS is an excellent novel multifunctional fluid additive (anticaving agent and borehole stabilizer, lubricant, and flow patern adjusting agent) as well as a good additive for reservoir protection ( borehole stabilizing and cleaning).
