  • The hyperbranched low molecular weight polyamine inhibitors presently in use have some deficiencies such as low density of primary amino groups and lack of inhibitive capacity in high pH environment. To overcome these deficiencies, an octaamino star-shaped low molecular weight polymer (OASS) with regular molecular structure and high density of amino groups was developed through twostep reaction with pentaerythritol as the raw material. Molecular simulation of OASS showed that the adsorption density of OASS on the surfaces of clays is almost the same as that of pentaerythrityltetramine (PTTA) and 3,3-bis(2-aminoethyl)-1,5-pentanediamine (BAPD), but the adsorption energy of a single molecule layer of OASS is significantly greater than that of PTTA and BAPD, indicating that the adsorption centers of the three polyamines on the clay surfaces are all provided by the amino groups, and OASS which has the highest amino group density has the highest adsorption capacity. Test on the adsorption capacity of OASS showed that at 25℃, the saturated adsorption capacity of OASS is only 1.12 mmol/L, and the molar concentration of OASS at saturated adsorption capacity I sonly 10 mmol/L. Laboratory experiment on the capacity of OASS in inhibiting clay yield and linear expansion, and in percent recovery of drilled cuttings in hot roller test showed that OASS is remarkably superior to PTTA and BAPD in inhibiting the yield of shale cuttings. Laboratory experiment also showed that OASS is compatible with filed drilling fluids and does not affect the rheology of the drilling fluids before and after aging. OSAA also helped improve the filtration control property of the drilling fluids. The results of the study have prove d that OASS has excellent inhibitive capacity and is well compatible with different drilling fluids.
