Abstract Oil and gas development has strict requirements for the seal ability of premium threaded connections (PTCs) tubing. Assessing joints can help reduce risk leakage after running string. Using experimental methods to investigate thread sealing capability is time-consuming expensive, furthermore, results finite element simulations are not accurate enough. To better address this issue, a hybrid method utilized as an advanced solution: we establish geometric nonlinear model tie it...
To effectively solve the problem of lost circulation and well kick frequently occurring during drilling abnormally high temperature pressure fractured-vuggy reservoirs in Tazhong block, a rigid particle material, GZD, with tolerance, rigidity (> 8 MPa) low abrasiveness has been selected based on geological characteristics theft zones reservoirs. Through static sealing experiments, its dosage when used alone combination lignin fiber, elastic material SQD-98 calcium carbonate were optimized,...
To accurately predict sustained annular pressure (SAP) resulting from tubing integrity failures in ultra-deep gas wells, a new prediction model is developed by considering the effect of leakage states points and interaction between volumes liquid leakage. First, calculation equation for SAP established analyzing coupling relationship multiple points. Then, tubing-casing annulus divided into several segments transient solved iteration methods. Finally, impact sizes number are mainly studied....
In the Huangjinba Block of Zhaotong National Shale Gas Demonstration Zone in periphery Sichuan Basin, two horizontal shale gas wells suffer severe casing deformation. this paper, geological and engineering characteristics strata around deformed interval were analyzed based on 24-arm caliper measurement deformation, open-hole caliper, electrical resistivity, drilling time logging, cementing CBL∖VDL CBL imaging. Then, data 3D imaged by imaging analysis software, to figure out morphologic...
