Since 2017, the technology has broken through the conventional seepage theory of sandstone
reservoir, realized the description of cave fluid characteristics through the introduction
of Bernoulli equation, and established four plane and vertical geological models:
well-cave-fracture, well- cave-fracture-cave, well-fracture- cave-fracture- cave,
well-fracture-cave-fracture-cave. Realize the characteristic parameter interpretation of
reservoir description such as the number, size, distance, fracture length and fracture
cavity combination structure, and form a relatively perfect theoretical system suitable for
well test interpretation of fracture cave reservoir types.
The previous research mainly focused on the theoretical research of fracture cavity well test
interpretation, and the application interpretation software has not been standardized; At
the same time, the physical meaning of parameters in the new theory focuses on the new
parameters of fracture hole well test, and whether other parameters have new physical
meaning has not been solved at present; In addition, the previous application shows that the
calculation results of fracture volume are generally too large, which is only relatively
sensitive to static parameters similar to fluid high-pressure physical properties.
Therefore, the project continues to be carried out.
