Abstract EN
The lost circulation in a formation is one of the most complicated problems that have existed in drilling engineering for a long time.
The key to solving the loss of drilling fluid circulation is to improve the pressure-bearing capacity of the formation.
The tendency is to improve the formation pressure-bearing capacity with drilling fluid technology for strengthening the wellbore, either to the low fracture pressure of the formation or to that of the naturally fractured formation.
Therefore, a laboratory study focused on core fracturing simulations for the strengthening of wellbores was conducted with self-developed fracture experiment equipment.
Experiments were performed to determine the effect of the gradation of plugging materials, kinds of plugging materials, and drilling fluid systems.
The results showed that fracture pressure in the presence of drilling fluid was significantly higher than that in the presence of water.
The kinds and gradation of drilling fluids had obvious effects on the core fracturing process.
In addition, different drilling fluid systems had different effects on the core fracture process.
In the same case, the core fracture pressure in the presence of oil-based drilling fluid was less than that in the presence of water-based drilling fluid.
