| titleOfInvention | Loss plugging agent for oil drilling and preparation method thereof |
| abstract | The present invention relates to a plugging agent for oil drilling and a preparation method thereof. The plugging agent for oil drilling of the present invention comprises a blended sintered product containing polytetrafluoroethylene and a metal screen. The method for preparing the lost circulation agent for oil drilling of the present invention comprises the following steps: step S1: preparing a polytetrafluoroethylene emulsion; step S2: forming a blend of the polytetrafluoroethylene emulsion and a metal screen, sintering the blend, Broken to obtain a leakage stopper. The invention obtains the lost circulation plugging agent for oil drilling with enhanced anti-high temperature and high pressure performance while retaining strong anti-slip performance through the combined use of polytetrafluoroethylene and metal screen. |
