Abstract
The invention provides a carbon dioxide foam injecting device of an oil well and relates to a mechanical device in an oil mine field. The carbon dioxide foam injecting device is composed of a cylinder body, a carbon dioxide inlet, a dosing port and a mixed liquid outlet. One end of the cylinder body is provided with the carbon dioxide inlet, the other end of the cylinder body is provided with the mixed liquid outlet, a side wall at one end of the cylinder body close to the carbon dioxide inlet is provided with the dosing port. The carbon dioxide inlet in the cylinder body is connected with a spraying pipe, and a stirring paddle is arranged on a fixing frame from the spraying pipe to a mixed liquid outlet space. The carbon dioxide foam injecting device of the oil well is novel in structure, low in construction cost and high-pressure-resisting, the cylinder body is made of stainless steel, and the material is OCr18Ni9 and can bear pressure of 25 MPa. Efficient flame retardant crystallized magnesium oxide is filled in a heater, an electric heat tracing band can heat a system at the temperature of 0-150 DEG C, and a temperature sensor externally-connected temperature control cabinet performs automatic control to a working state of an electric heating pipe. The carbon dioxide foam injecting device solves the problem of frozen blocking in the carbon dioxide foam oil-displacement process and effectively ensures the foaming performance of a carbon dioxide foam system.
Description
Technical field
The present invention relates to the plant equipment on a kind of oilfield, relate in particular to a kind of oil well carbon dioxide foaming injection device.
Background technology
In petroleum industry, more early stage foam maker is mainly used in the foam technology for washing well, along with to the progressively research of foam on the petroleum drilling and mining field; China has carried out utilizing aerated fluid to carry out field trial researchs such as profile control and water plugging, acidifying strata, well cementing of cement, pressure break, sand-flushing, drilling well, water pumping gas production and foam steam flooding in most produce oil base; And obtain effect preferably, foam is a kind of compressible gas-liquid mixture, is using foam maker from theory analysis from the past; The place that also comes with some shortcomings; Can not bear bigger pressure, the etching problem of not considering in the application in oil-gas field development, the low-density aerated fluid that its structure design produces can not satisfy the needs of oil field produced on-site fully; Foam quality is low; Blowing agent can not mix with carbon dioxide liquid fully, can not be because of reality need carry out adjustment etc., especially carbon dioxide foaming drive injection well mouth CO to it
2-20 ℃ are absorbed heat in the gaseous state conversion process by liquid state and to cause foaming agent to freeze the situation of stifled surface line and pit shaft.
Summary of the invention
The present invention is intended to the deficiency that exists in the background technology, and a kind of oil well carbon dioxide foaming injection device that provides.
Oil well carbon dioxide foaming injection device of the present invention; Be to constitute by cylinder body, carbon dioxide inlet, dosing mouth and mixture export; One end of cylinder body is provided with carbon dioxide inlet, the other end is provided with mixture export, on the sidewall of the end that enters the mouth near carbon dioxide of cylinder body, is provided with dosing mouth; The carbon dioxide inlet connects injection spray pipe in the cylinder body, and injection spray pipe to the fixed mount in mixture export space is provided with paddle.
As further improvement of the present invention, be wrapped in heater and protective cover arranged and cylinder body fixes in the cylinder body periphery.
As further improvement of the present invention, heater is outside cylinder body, to twine electric-heating belt and wrapped up by crystal magnesium oxide.
As further improvement of the present invention, on injection spray pipe, be thick with nozzle.
As further improvement of the present invention, on the inboard wall of cylinder block of mixture export, be provided with temperature pick up.
Oil well carbon dioxide foaming injection device of the present invention, novel structure, cost are low, high pressure resistant, and cylinder body is processed by stainless steel, and its material is OCr18Ni9, meets national relevant design requirement, but pressure-bearing 25MPa; Have the adjustable function of temperature, filling efficient flame-retarding agent crystal magnesium oxide in the heater, electric-heating belt can carry out 0～150 ℃ of heating in the scope to system, and temperature pick up outreaches temperature-controlling cabinet the duty of electric-heating belt is controlled automatically; Can fully stir, the cylinder interior mesh structure makes liquid carbon dioxide reach spray effect, and the helical stir oar stirs blowing agent and carbon dioxide liquid.The invention solves the stifled problem of freezing of carbon dioxide foaming oil displacement process, and guarantee the foam performance of carbon dioxide foaming system.
