| titleOfInvention | Oil（Water）Well envelope is altered, leak stopping system prepares and application process |
| abstract | Oil（Water）Well envelope is altered, prepared by leak stopping system and application process is field of oilfield chemistry, it compensate for oily (water) the well sealing skill in oil field, the deficiency of sealing current state of technology, it is made up of pre- stifled system and closure system two parts, and closure system is made up of following material component：Oil well G class g cements 40 50%, ultrafine slag powder 15 20%, polymer dispersion powder 8 15%, SILICA FUME 8%, UEA H swelling agents 12%, polyacrylic fibre 2%, USZ drag reducers 0.2 0.5%, GH 1 (or GH 7) retarder 0.1 1.5%；Pre- stifled system has pre- stifled system 1 and the pre- two types of stifled system 2；System of the present invention is simple with liquid, and rheological characteristic, injection are good, system plastic, hardening time is adjustable controllable, construction safety；Suitable for oil under the complex geological condition such as loose stratum in debt, fractured reservoir and seam, hole type limestone formation（Water）Well envelope alter, leak stopping, sealing operation, be also suitable for missing the leak stopping returned in drilling process greatly. |
