Influence of stratigraphic dip on production in gas-breakout period in deep, thin interbed reservoir;

DDQC formation dipmeter tool and its application.;

Drilling through the thrust block in the well Longshen-1 had encountered the problem of strong natural formation deflection tendency due to high formation dip variation.

The relationship of drilling fluid density and formation dip with borehole undergauge creep deformation encountered in salt beds in Xinjiang Oilfield drilling was studied.

Since there are many kinds of dip log data processing softwares,so their processing methods and parameter choices are quite different.

Da-5 well is situated in Dalaisumu Block of Erlian Basin in Inner Mongolia,with the major coring layer in part of Tenger and the upper part of Arxan section,which makes it difficult to core for the serious interbedding of high abrasive and friable strata,steep dip and lithilogical change.

The fault block oil fields with multiple rock salts in Jianghan Oil Region are influenced both by rock salts and faults,formation dip angles are generally large.

Construction mechanics caused by different construction procedures under different slope angle of surface ground are analyzed based on a plain strain problem using Druck-Prager yield law in a partial pressure double-arch tunnel.
