ABSTRACT

Establish the new drilling fluid technology to protect low- and extra-low-
permeability reservoirs and the trapezoid protection water-injection technol-
ogy for low-permeability and extra-low-permeability reservoirs via changing
the wettability of rock surfaces of the reservoirs by using the established gas
wettability theory of rock surfaces, and improve the yield of a single well and
the injection capability of water wells; establish the drilling fluid cuttings car-
rying technology and the microemulsion oil removal technology via realizing
the wettability of cuttings surface to ensure the cleanliness of wells and the
harmlessness of cuttings, and introduce the field applications of these
technologies.
