Abstract:The paper introduced the strata lithology and particularity of a K - Mg salt deposit. According to the results for more than 20 experiments and applications, dissolution causes of different drilling fluids in different saline strata were analyzed. With improvement and optimization, the suitable formulas for drilling fluid were summarized for halite layer, sylvine layer, earnallite layer and some other dissolubility halite strata.

Abstract:Simulation analysis of force was made on guiding blade of short helix bit based on SolidWorks. Relation of variation between helix cone angle and the lowest safety factor revealed that when guiding helix bit was under pressure, the safety factor increased with the helix cone angle enlarging simultaneously, and would reduce at a certain value.
