Description
Technical field
The utility model relates to oil and gas exploration technology field more particularly to a kind of horizontal well with bottom water reservoir AICD are complete
Well control water installations.
Background technique
AICD (Autonomous Inflow Control Devices) is that one kind can control automatically incoming fluid
To alleviate bottom water coning, (under reset condition, the blocky oil of bottom water, the grease of gas reservoir or air water are distributed system by gravity relationship, when oil, gas
After well is gone into operation, oil, inside gas-bearing formation due to the influence of oil, water or gas and water gravitational difference, make be originally horizontality oil-water interfaces or gas
Water termination is deformed into mound shape and bores, and is called water cone.As oil recovery, gas velocity degree increase, water cone constantly rises, and breaks through and enters shaft bottom,
It causes grease or air water with producing, reduces oil, gas yield, this bottom water is called with oil recovery, the tapered process being longitudinally propelling of gas
Bottom water coning.) to reach the device that oil field control water protects oily effect.(when getting into target zone position, well section gradient is super for horizontal well
85 degree are crossed, horizontal distance is more than 10 times of target zone thickness of well horizontal well.) be widely used in bottom water reservoir, thin layer reservoir,
The recovery process such as ocean shallow water and deep water hydrocarbon hiding, horizontal well have big advantage compared with straight well, greatly improve oil gas
The exploiting economy in field.But the production profile of long horizontal well is generally difficult to balanced propulsion, easily at the hypertonic interval of oil well, crack
Premature water breakthrough.Bottom water (oil/gas hiding in, entirely the oil/gas layer bottom within the scope of boundary containing oil/gas/edge hold in the palm oil/
The water of gas is bottom water.) oil reservoir development process in, once there is bottom water coning, will greatly shorten oil reservoir water-free oil production period.
Meanwhile the moisture content of horizontal well is accelerated to rise, and bottom water coning occurs and breaks through, and the water-blocking operation after bottom-water breakthrough is very tired
Difficulty has seriously affected the embodiment of horizontal productivity advantage and has exploited the realization of comprehensive benefit, becomes restriction horizontal well and efficiently opens
The crucial problem for sending out bottom water reservoir may be forced closing well if serious if handling or dealing with improperly not in time.Big portion of China
The bottom water reservoir of point horizontal well development has been in high water cut rate, producing well with aqueous raising and yield declines rapidly.For
This problem has developed a variety of water control devices (ICD) for flowing into structure, including nozzle type, labyrinth type, helical duct type both at home and abroad
Etc. structures, but the ICD of passive type there are flow resistance level constant, see water/gas failure the problems such as.
A kind of density sensitive type AICD (design obtains S.L.Crow in 2006 et al. earliest), the dress exists in the prior art
It sets and is made of expanded rubber, clump weight, density sensitive piece, gravity ring and gravity ring balance weight.Gravity ring is equipped with flow channel,
If tolerance is excessive during oil-producing, since buoyant gas is smaller, density sensitive piece is closed downwards, and gas not can enter stream
Enter channel, to limit gas output.When viscosity-sensitive valve is inverted, the output of water can be limited.When producing dilutional hyponatremia, density
Sensitive piece is closed upwards by buoyancy effect, and water not can enter flow channel, and when water cone is decorporated, density sensitive piece is opened downwards,
AICD restarts oil-producing.There are moving components in the device, after prolonged use it is possible that moving component failure etc.
Problem does not allow to replace the movement of failure at any time since oil reservoir production actual conditions are complicated and consider economic benefit in principle
The service life of component, the device is restricted.
The present inventor based on years of experience and practice in relevant industries, proposes a kind of horizontal well with bottom water reservoir as a result,
The complete well control water installations of AICD, to overcome the deficiencies of existing technologies.

Enter mobile equilibrium, controls bottom water coning, extend the water breakthrough time of oil well, to extend the service life of oil well.
Further, sprue 22 is in identical setting with the cross-sectional diameter of branch flow passage 23, so that the inflow pressure of oil and water
Substantially it is consistent.
Further, as shown in Fig. 2, the angle α between sprue 22 and branch flow passage 23 is in 60 °.Sprue 22 and branch flow passage
Angle α between 23 can be adjusted according to the actual situation, and 60 ° are optimal angle degree.
In a specific embodiment of the utility model, it is 3 that fluid, which flows into 2 quantity of structure, and 3 fluids flow into structure 2
Circumferentially uniform intervals are arranged.
Liquid numerical simulation analysis and meter are carried out to designing a model for the complete well control water installations 100 of horizontal well with bottom water reservoir AICD
It calculates, obtains speed cloud atlas and pressure cloud atlas, be used for theoretical research.The operating condition of analysis is divided into three kinds, and first is the condition in pure oil
Under, taking the viscosity of oil is respectively 1,20,50,70 (units: MPa.s), is verified between flow velocity and pressure drop oily under different viscosities
Relationship；Second is under the conditions of pure water, and the density of water intaking is respectively 1000,900,800,700 (units: kg/m2), and verifying is different
The relationship of flow velocity and pressure drop that density is lauched；Third be under conditions of oil mixing with water, moisture content difference 20%, 40%, 60%,
80%, verify the flow velocity of oil mixing with water phase and the relationship of pressure drop under different water cut.
The speed cloud atlas of pure oil and pure water is compared, pure water enters the speed that Cylinder Shell enters Cylinder Shell than pure oil
Degree is fast, and pure water generates biggish inertia force and then the high speed rotation in cylindrical shell body, and oily viscous force is larger, and speed becomes
Change is slower, and speed increases at nozzle；Pressure cloud atlas comparison to pure oil and pure water, pure water are big from entrance to injection differential pressure
In pure oil, illustrate that water produces parasitic pressure drop when high speed rotation in cylindrical shell body；According to the corresponding speed of oil mixing with water
When spending cloud atlas and pressure cloud atlas, water mainly enters from tangential sprue, and high speed rotation is then generated in cylindrical shell body, oil
Mainly enter from radial branch flow passage, reach nozzle through shortest path, the pressure drop that water generates is greater than the pressure drop that oil generates, therefore bottom
The complete well control water installations 100 of water reservoir horizontal well AICD can be effectively controlled the output of water.
