Description
Technical field
The invention belongs to oil extraction in oil field technical field, and in particular to a kind of horizontal well automatic water control device.
Background technology
At present, High water cut horizontal well is administered, and mainly carries out horizontal well water exploration, water plugging of horizontal well measure, or to bottom water
Oil reservoir specific aim carries out the control water completion tubular columns such as tune stream water-control sieve tube, but these measures generally there are long construction period, control water effect
The low problem of rate, it is impossible to meet the extensive Efficient Development of current horizontal well, in particular for cased hole completion, low yield horizontal well
Administer, at present still without efficient control measures and method.
The representative means of horizontal well water exploration mainly have liquid producing profile log water detection, Neutron Hydrogen activation test water detection with
And segmentation production test water detection.
Horizontal well liquid producing profile log water detection technology, by turbine flowmeter start discharge capacity, horizontal well interval laminar flow etc. because
The impact of element, measuring accuracy are relatively low, are simultaneous for low-permeability oil deposit low production liquid horizontal well, and technological adaptability still has much room for improvement；
Neutron Hydrogen activation test water detection technology is had high demands to horizontal well Liquid output, to producing liquid 10m daily3/ below d well test
When, not detecting peak value, it is impossible to explain, the technology equally cannot be applied in low-permeability oil deposit, low discharge horizontal well；
For effectively solving low production liquid horizontal well water detection technical problem, research defines horizontal well in segments production test water detection
Technology, determines water exit interval by production paragraph by paragraph, aqueous chemical examination, relatively low to the requirement of horizontal well Liquid output, but the technology is many
On section transformation horizontal well during water detection application, the water detection cycle is long（Average 30-40 days/well）, reduce horizontal well water exploration measure efficiency.
Water plugging of horizontal well mainly has chemical water shutoff, mechanical packer blocking water.
So far, for horizontal well chemical water shutoff, due to different oil reservoirs, different completion mode horizontal well pair chemical plugging agents
Harshness is required, the blocking agent product for maturation at present in terms of blocking agent research and development, not yet occur, in particular for low-permeability oil deposit, level
Well chemical plugging agent is still in the research and development test stage.
Horizontal well machinery packer blocking water is relatively easy, has been developed that the supporting bridging plug of horizontal well machinery water blockoff, envelope at present
Every device, technology relative maturity, but for the measure of casing tube well-completion horizontal well machinery blocking water as water exit interval pressure is higher, water blockoff
Afterwards it occur frequently that set outside tube water circumferential motion problem, causes the horizontal well machinery blocking water term of validity short, water plugging effect reduces.
