Abstract
The utility model discloses a kind of Self-adjusting sandcontrol pipe, include the base tube of through hole, and be fixedly installed on the protective sleeve with hole of base tube periphery; Between described protective sleeve and base tube, ecto-entad is disposed with iron wire stratum reticulare, elastic layer, adsorption layer and air bag; Described elastic layer is made up of cavernous body; Described adsorption layer is made up of active carbon; Run through in described elastic layer and be provided with capillary channel; Run through in described air bag and be provided with through hole; Described through hole connects with air sac sealing; The utility model achieves the function of sand control to a great extent, simultaneously by the inflation/deflation operation of air bag, achieve the function of automatic de-plugging, avoid and adopt Traditional Man mode to carry out de-plugging, not only increase de-plugging efficiency, avoid the damage of sand control installation simultaneously, improve the application life of sand control installation.
Description
Technical field
The utility model is specifically related to a kind of Self-adjusting sandcontrol pipe, belongs to the oil in petroleum works, hydraulic engineering, well completion technique field.
Background technology
The sand control installation adopted in the Well Completion Engineering of Oil Reservoirs of existing oil, well, as ceramic capillary sand screen, is all the principle based on gap or fracture filtration, allows formation fluid, flows through this sand control installation face and be blocked in outside pit shaft by sand grains as oil, water etc.But due in recovery process, the Liquid output of every mouthful of well, the swabbing pressure of mining equipment and the sand production rate on stratum, the domain size distribution of sand grains are the processes of a dynamic change, and the gap of such sand control installation or the size of hole immobilize, cannot regulate, thus there is following deficiency in prior art: 1, sand grains easily blocks gap, and very easily block; 2, whole sand control installation needs to adopt manual type to carry out de-plugging, there is the shortcoming of de-plugging inefficiency; 3, by after manual type de-plugging, be easy to damage gap original on sand control installation, thus be easy to the damage causing sand control installation, thus reduce the application life of sand control installation.
Summary of the invention
For the problems referred to above, it is simple that the technical problems to be solved in the utility model is to provide a kind of structure, practical, effectively can realize sand-proof function, has de-plugging convenient, the Self-adjusting sandcontrol pipe that de-plugging efficiency is high simultaneously.
Self-adjusting sandcontrol pipe of the present utility model, includes the base tube of through hole, and is fixedly installed on the protective sleeve with hole of base tube periphery; Between described protective sleeve and base tube, ecto-entad is disposed with iron wire stratum reticulare, elastic layer, adsorption layer and air bag; Described elastic layer is made up of cavernous body; Described adsorption layer is made up of active carbon.
Further, run through in described elastic layer and be provided with capillary channel.
Further, run through in described air bag and be provided with through hole; Described through hole connects with air sac sealing.
The utility model beneficial effect: a kind of structure of the present utility model is simple, practical, effectively can realize sand-proof function, has de-plugging convenient, the Self-adjusting sandcontrol pipe that de-plugging efficiency is high simultaneously; The utility model, by the setting of silk screen layer, elastic layer, adsorption layer and air bag, achieves multiple sand control structure, has good sand control capability; By having the setting of flexible cavernous body, and have the capillary channel of variable aperture in cavernous body, the aperture of capillary channel can change along with swabbing pressure fluctuation, and the sand grains of adhesion is few, thus not easily blocks up sand; By the setting of adsorption layer of living, carry out filter sand operation further; By the setting of air bag, when air bag carries out inflation/deflation, air bag carries out enlargement and contraction operation, thus make adsorption layer, elastic layer and iron wire stratum reticulare carry out expanding outwardly and inwardly shrinking operation, thus the sand grains sticked in elastic layer and adhesion layer is extruded, achieve the function of automatic de-plugging; The utility model achieves the function of sand control to a great extent, simultaneously by the inflation/deflation operation of air bag, achieve the function of automatic de-plugging, avoid and adopt Traditional Man mode to carry out de-plugging, not only increase de-plugging efficiency, avoid the damage of sand control installation simultaneously, improve the application life of sand control installation.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of air bag.
Detailed description of the invention
Self-adjusting sandcontrol pipe as depicted in figs. 1 and 2, includes the base tube 1 of through hole, and is fixedly installed on the protective sleeve 2 with hole of base tube 1 periphery; Between described protective sleeve 2 and base tube 1, ecto-entad is disposed with iron wire stratum reticulare 3, elastic layer 4, adsorption layer 5 and air bag 6; Described elastic layer 4 is made up of cavernous body; Described adsorption layer 5 is made up of active carbon; Run through in described elastic layer 4 and be provided with capillary channel; Run through in described air bag 6 and be provided with through hole 7; Described through hole 7 seals with air bag 6 and connects.
The utility model, by the setting of silk screen layer, elastic layer, adsorption layer and air bag, achieves multiple sand control structure, has good sand control capability; By having the setting of flexible cavernous body, and have the capillary channel of variable aperture in cavernous body, the aperture of capillary channel can change along with swabbing pressure fluctuation, and the sand grains of adhesion is few, thus not easily blocks up sand; By the setting of adsorption layer of living, carry out filter sand operation further; By the setting of air bag, when air bag carries out inflation/deflation, air bag carries out enlargement and contraction operation, thus make adsorption layer, elastic layer and iron wire stratum reticulare carry out expanding outwardly and inwardly shrinking operation, thus the sand grains sticked in elastic layer and adhesion layer is extruded, achieve the function of automatic de-plugging.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
