Abstract:

Borehole stability in shale/mudstone strata is significant during the construction of horizontal well for unconventional hydrocarbon reservoirs, which is caused by two mainly reasons, one is the current borehole stability design model using simply isotropic media model and Mohr-Coulomb criterion, and the other is the inappropriate performance of drilling fluid. To solve this problem, a new borehole stability model for water-sensitive formation was established, which adopted transversely isotropic media model, Mogi-Coulomb criterion, and the effect of hydration to rock strength. The influence of deviation angle, azimuth, drilling fluid performance and drilling time on collapse pressure were analyzed. The results showed that transversely isotropic model was more suitable to describe strength anisotropy for laminated shale/mudstone;collapse pressure calculated by Mogi-Coulomb criterion is more consistent with drilling practice than Mohr-Coulomb, in this case, lower drilling fluid density can be used to keep borehole stability and promote rate of penetration;enhance sealing capacity and decline shale hydration diffusion capacity were helpful to extend collapse cycle. Several examples of shale gas horizontal wells drilled in Dongpu, Weiyuan and Jiaoshiba districts confirmed that the recommended method is highly reliable and effective.

Key words: transversely isotropy, mudstone/shale, deviated borehole, collapse pressure, borehole stability, drilling
