By way of analysis broken membrane pressure importance to control the high-speed combustion engine ignition blocking up piece,and effective control of testing methods,technology of broken membrane pressure,thus stabilizing product performance.

Prediction of formation fracture pressure with logging data in Tahe oilfield;

Rock mechanical parametric experiments and the research of formation fracture pressure prediction

Effects of crustal stresses and natural fractures on fracture pressure of coal reservoirs

Determining breakdown pressures in transversely isotropic formation by multipole array acoustic logs;

By combining with formatting density logging,we calculated parameters of rock elasticity and intensi- ty using multi-pole array acoustic logging,and performed for- rnation stress analysis to determine breakdown pressure and drilling fluid density.

Then breakdown pressure,caving pressure and drilling fluid density can be obtained,which will act as references for drilling design to guide safe drilling.

Study of burst pressure calculation method of pipelines with axial flaws;

The burst pressure of filament wound pressure vessels and the ratio of strength transfer of fiber;

The prediction of the burst pressure of pressure vessels with miter pipe

The broken pressure of the two compound materials was tested.

On the basis of the test results of a full scale hot state explosion test a calculation and analysis was conducted of the explosion pressure of the following: square box test parts, nodular cast iron boiler, grey cast iron boiler and grey cast iron boiler plates.
