According to the data analysis of fracturing fluid back flow after large-scale fracturing,
this project comprehensively considers the water content, pressure data and production data,
and studies the production data simulation method under single well and multi-well
interference, and makes use of the obtained formation data to study the productivity
evaluation method. The main technical contents are as follows:
Study on the characteristics of well testing curves considering
the start-up pressure gradient and the stress sensitivity:
Establishing a
formation seepage equation considering the starting pressure gradient and the stress
sensitivity, and simultaneously carrying out the solution study of the seepage equation of
the dense oil reservoir, the correlation algorithm is the fundamental of large-scale
fractured well testing interpretation.
Low-permeability test well and production capacity full-history
simulation new technology:
The invention provides
a low-permeability test, a full-history simulation and a simulation new technology, and
solves the problem of low utilization rate of the data of the exploration well.
Forming a calculation method of fracturing well grid productivity
evaluation, and providing a calculation tool for the interpretation of a large-scale
fracturing well testing.
A unified communication protocol and data interface are developed
based on the software architecture design of the component, so that the component can be
easily reused.
