During drilling,on basis of analysis of the geological environment,optimization of hole structure,use of high efficient drilling bit,optimization of cementing method,and application of protective technology of oil and gas reservoirs, it reached good and fast drilling in the block.

High ROP drilling fluid is formulated by adding fast drilling additives into the mud without altering the original rheology, solids content and the dispersibility of the mud, thus greatly improves the lubricity of the mud and reduces the torque of the drill pipes.
