Casing is the major structural component of a well. Casing is needed to:
Maintain borehole stability
Prevent contamination of water sands
Isolate water from producing formations
Control well pressures during drilling, production, and workover operations
Casing provides locations for the installation of: Blowout preventers
Wellhead equipment
Production packers
Production tubing
The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors, and setting depth is a primary engineering and economic consideration.

Our zyd series double-stage transformer oil purifier can quickly remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil's dielectric strength, effectively making sure electric equipments working safely and normally.
It is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil.It can be used for filtration of more than 110v substation live line work onsite.Meanwhile, series zyd oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.
Advanced technology:
1.Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value = 5pa.
2.Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
3.Duplex-stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
4.Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies.
5.Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
6.Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
7.Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak.If there is any fault, machine will be power off automatically.
8.Functions of live line work onsite, vacuum drying and vacuum oil filling.
We specialized in making 5-1000Ton oil press project, 20-1000Ton solvent project, 1-600Ton refining project. We have moren then 40 years' experience in oil machinery field, and is one of China national top ten brand.
Product instructions:
The type of thy-21ce oil quality analyzer is an upgrade version of the type of thy-21a oil quality detector. Due to install a large-screen monitor to realize operating prompt and chinese characters of each function, convenient to read various data. It is installed a micro printer and uses a high-precision a / d conversion circuit, so that the analyzer repeatability is better. When the power of battery is low, the buzzer will alarm automatically and prompt. The analyzer has a dual function of dc and ac (dc can work continuous for 28 hours), in no man operation condition will shut down automatically; when ac power work can charge. The analyzer has exquisite appearance, easy to operate, suitable for on-site and field operations.
Main functions:
?determining the degree of pollution in lubricant within 5 minutes;
?detecting percentage of water content in the lubricant within 3 minutes;
?detecting metal particles beyond 60um;
?determining the new purchased lubricant is qualified or not;
?printing the result after finishing the detecting
Applications:
For the present thy-21ce oil quality analyzer is applied to various fields such as aerospace, oil field, ports, transport, mine, electricity, metallurgy, chemical industry and engineering plant., etc.
Our company can supply various offshore drilling rigs, onshore drilling rigs, work-over rigs and their spare parts. The main products include 3000m, 4000m, 5000m and 7000m drilling rigs.

Overview
Products Description
The Composite Bridge Plug is made from composite material and easy to drill out. It is mainly composed of mandrel, rubber, slips, cones, protection bowls, release/start pins, lower sub and so on. The composite bridge plug is mainly used for provisional plugging in oil and gas well, and fracturing construction
Working principle
The opposite power produced by setting tool (wire line or transmitting hydraulic pressure in oil tube) acts on the lower sub, shears the starting dowels and exerts compressive force on rubber through cone. Inside the tension range slips dehisce and inlay the in wall of the casing, rubber expand to the in wall of the casing and seal up it, finish setting. When the tension rises to the shear rating, the starting dowels be sheared and the setting tool separates from the bridge plug, finish releasing. After taking out the setting tool, the frac ball that be put into the well will work hermetically with the head face of the mandrel. The plug can be quickly drilled out under the necessity of the after steps
Drilling out
Recommend the use of special milling tools. Recommend rotation rate: 60~150rpm, bit weight: 5~15kN, viscosity of drilling plug fluid:15~30mPas and minimum cyclic velocity: 36.6m/min, to make sure the debris circulates out. After the preparation is done, start the screw drill and drill slowly into the bridge plug. Ensure continuous drilling speed by applying drilling pressure. The torque added to the drilling tool should not be greater than the recommended value. Excessive drilling pressure increases the friction resistance of the pipe string and results in large pieces of debris which must be salvaged separately.
