Dual Completion Wellhead

DESCRIPTION:
Our independent innovation of patent technology such as whole combination valve
type Dual Completion Wellhead, valve stem self-styled type composite seal, double
seat plate valve, two-way counter balance valve etc. With high technical content,
strong ability to resist bad working conditions, completion tools can enhance oil
recovery efficiency, oil well productivity directly.
New type of Dual Completion Wellhead, can hang two pipe string at the same time, to
work at different oil reservoir in the meantime. Or extract oil and water infusion at
same oil reservoir, make each oil reservoir of the whole well completely exploited,
improve recovery efficiency. When exploit oil (gas ) in different oil reservoirs at the
same time, put two sets of tubing in casing to different oil reservoirs, with the packer
to separate two sets of tubing, based on the characteristics of different oil reservoirs,
exploit different oil reservoirs. Has the following advantages:
A. Relief low pressure oil reservoir, increase oil well output;

B. Can take the whole quasi-small layer of information, control the speed of sleep up
to extend the low water cut;
C. Form two absolutely independent of oil production system, can give full play to
the production capacity of each reservoirs, extract oil and water infusion at same oil
reservoirs, make each oil reservoir of the whole well completely exploited, improve
recovery efficiency.
From the development trend of the oil and gas wellhead, both at home and abroad,
gusher well dual Completion Wellhead all can use two tubing in one well working in
the meantime, improve production efficiency. For heavy oil well and old well later
stage working, steam injection, water injection, injection pressure at the same time
improve production efficiency, reduce production cost; For marine Wells, use
combination valve can reduce the height of the wellhead, reduce occupied area,
improve production efficiency.

Can complete with different (pneumatic) hydraulic safety valve.
Design with assembling and disassembling dual tubing hanger quickly.
One well bore can exploit two different strata at the same time, and can
control and operate separately.
Compact configuration, convenient operation, reliable seal.
Apply to all kinds of casing and tubing program.
