Based on the drilling information in Changzhou City, stratum standardization and 3D modeling of strata, underground structures and pipelines were conducted in the built intelligent system.
Based on the drilling tool-regolith interaction model, two identification methods for determining the planetary regolith bearing and shearing parameters are proposed.
Third, a gas reservoir permeability computational model for underbalanced drilling was deduced based on the drilling parameters, and empirical models of the porosity and saturation were derived using core test data.
To find a solution for this problem, the cuttings transport mechanism was analyzed based on the drilling mud hydraulics, and then, an equation of cuttings transport distance was derived.
Based on the drilling and completion data and microseismic monitoring data of Sichuan shale gas horizontal well X201-H1, three-dimensionalonal finite element model of volume fracturing is established, combining fluid-solid interaction mechanics with the basic theory of rock damage mechanics.
Based on the drilling and well completion data, microseismic surveillance data, theories of fracture mechanics, rock damage mechanics and rock failure criterion, this paper established a finite element model of the formation of effective stimulated reservoir volume, including clustering perforation casing for X-1 h shale gas horizontal well, to address the problems.
A method for constructing regional formation pressure based on the drilled wells logging data was established.
Based on the drilling data source and completion program, this test was to estimate the skin factor and initial reservoir pressure in this area, which was needed for the next drilling operations (Table 1).
