| Abstract: | In order to finish the exploration goat, thesealing and anti-caving was developed, and itrs density was from 1.20 to 1.80g/cm3. The drilling fluid system had high heat tolerance, sedimentation stability, inhibition and formation sealing performance, and the capability of anti-clay contamination was strong. The drilling fluid system was applied in the fourth interval of Wucan 1 well with good effects. The problems inclu ding borehole wail instability in complex formation and high-temperature stability of drilling fluid in ultradeep well were solved, and designing goal and geological exploration task were finished. At last, the success of drilling the well provide the basic data for deep research reservoir forming conditions in Wulungu depression and arrangement further exploration. |
