| 摘 要： | 针对难以堵漏的恶性漏失地层和水泥封固效果不良的垮塌层,开发出新型可固化工作液。该工作液以常规钻井液为基础,具有优良的悬浮能力、流变性和抗盐能力,与钻井液相容性良好,在一定条件下能固化达到一定强度。可作为堵漏液使用,也可在井壁失稳地层作为封固液使用,能有效提高堵漏成功率和对失稳地层的封固效果。

| Abstract: | According to the collapsing formation which is difficult to control the severe leakage and can not be effectively cemented, a new settable working fluid was developed. It is based on the conventional drilling fluid with good suspension capacity, rheological property, salt-resistant ability and good compatibility of drilling fluid, its suitable solidification inten- sity can be reached under certain conditions and can be used as sealing fluid or as cementing fluid in borehole instability formations to improve the sealing and cementing effect. |

| Keywords: | leakage sealing concretion solidification working fluid |
