According to the petrography character in Yan 227 block and the technology difficulty of horizontal well, aluminium and amine drilling fluid with high inhibition, lubrication and anti-caving ability was researched and developed. The drilling fluid had good inhibition, lubrication property and high formation sealing performance. The drilling fluid was applied in Yan 227 block, and these problems occurred in long horizontal interval of wellbore stability, hole cleaning and lubricating to anti-sticking were solved with the cooperation of wellsite drilling fulid technology and technics. At last, the successfully of drilling laid the foundation for further accelerating the development process in the block.
