Oil well cementation mud high temperature and high salt filtrate reducer AC-Y
The cementation of clay, especially colloidal particle, plays an important role in the structural stability of soil samples.
The scale of development and reservoir quality of laminar algal limestone and stromatolite algal limestone are controlled by the sedimentary environment, early solution and late cementation.
The porosity loss caused by cementation is 25.8% and 27.5% of the total porosity for the Chang 1—Chang 3 sandstones and the Chang 4+5—Chang 10 sandstones, respectively.
Temporal cementation is widely used in many clinical situations, including temporization of provisional and permanent restorations, and progressive cementation of cement-type implant prostheses.
Study on the preparation of the inner TiC coating made by pack cementation method
The poorly-developed pore texture of the sandstone is caused by strong compaction, early poor cementation of carbonate and late poor dissolution of carbonate.
The cementation of the conglomerate, dating back to the Jurassic period is so compact that it has hardened into rock and comes into contact with the limestone of the ordovician system in angular uncoformity.
It is the calcite cementation that results in the variation of carbonate mineral contents.
We are also discussed subgingival contours, provisional restoration, final impression, occlusal adjustment and final cementation to assure successful results.
The excel in low density oil-well cement main solution oil field low pressure, the low seepage, easy to leak the lost circulation question which in the stratum well cementation appears.
Influence of carbonate diagenesis on carbonate reservoir A case study from cementation
Usage: When pouring into-cement, keeping apart cement mortar and mud and preventing cement mortar from mixing into mud for not influencing quality of well cementation.
Other factors that affect porosity are compaction, consolidation and cementation.
Unconsolidated sand reservoir always be buried not deep, because of it's low cementation and high content of clay and sundry, the unconsolidated rock is easy to sanding during exploitation.
Preparation of SiC/Cr-Al-Si coating for C/C composites by two-step pack cementation method
The synthetic unconsolidated samples with weak cementation and high porosity were prepared using physical simulation technique.
Diatoms biological functions on subaerial Karst sedimentation are studied chiefly in this paper, including assimilation, tapping and felting effects, encrustation, cementation.
fluidized cementation tank
Knowledge of the chemistry of pore fluids and their effect on the stability of minerals can be used to predict where porosity may be destroyed by cementation, preserved in its original form, or enhanced by solution of minerals by formation waters.
