Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of downhole tool is that a kind of oil well is used bottom hole production allocator.
Background technology
Along with oil field development get in high water-cut stage, contradiction becomes increasingly conspicuous between oil reservoir, after a large amount of underground water is disabled extraction, carries out on ground that later separation is handled, re-injection has consumed great amount of cost again.How to find out and the high aquifer of shutoff, the low aquifer of exploitation effectively reduces cost for oil production, is a technical barrier that needs to be resolved hurrily that faces the oil field development midium or long term.
At present, there are producing profile testing water detection technology, packer water detection one water-plugging technique, underground hydraulic pressure switch to transfer layer to look for water-plugging technique, down-hole motor switch to transfer layer to look for four technology of water-plugging technique to address this problem.But these several kinds conventional water-plugging techniques only are applicable to the complete shutoff of clear and definite water-yielding stratum, have sacrificed the oil productive capacity of plugged zone, and can't dynamically adjust each interval production fluid amount according to each interval production fluid situation of change, are difficult to satisfy the needs of the present condition of production.
In recent years; Deficiency to above-mentioned technology exists has worked out rod-pumped well and has crossed annular space regulating multi-zone production rate technology, and this technology can realize the dynamic adjustment of each interval production fluid amount under the rod-pumped well working condition; But this Technology Need uses cable to be lowered to annular space joins and produces appearance and carry out layering allotment construction; Therefore, construction cost and security risk increase, and The field is restricted.
The utility model content
The purpose of the utility model is: provide a kind of oil well to use bottom hole production allocator; Use electromechanical integration technology; Suppress flexible completion down-hole through the ground water filling and join product adjusting action; Realize that production mandrel and the multiple-string packer tubing string of giving up combines, effectively solve the looking for of high-water-cut oil-producing well, water blockoff and join the product problem.The existing rod-pumped well of solution is crossed annular space regulating separate stratum production string instrument and is joined the product method and need descend wireline operation could realize the deficiency that the regulating multi-zone production rate survey is transferred.
The technical scheme that the utility model adopts is: oil well is used bottom hole production allocator; Mainly be made up of Connection Block, unidirectional valve ball, check valve body, top connection, shutoff spool, connecting rod, motor reducer, on-off controller and battery, there is external screw thread at the top connection two ends, and the lower end of top connection is connected the upper end of Connection Block; There is external screw thread the lower end of Connection Block; Can be connected with down-hole string, it is characterized in that: the middle part has valve body, a side of valve body that axial levels bit string circulation passage is arranged in Connection Block; Centre bit is equipped with a valve body fixing hole in the upper surface of valve body, in the valve body fixing hole, is fixed with a cylinder bodily form check valve body, between the outer wall of check valve body and the top connection inwall annular space is arranged; A unidirectional valve ball is arranged in check valve body; Side opening is arranged at the bottom in check valve body, and side opening is in the bottom of unidirectional valve ball; The oil recovery wing passage is arranged on the Connection Block sidewall, and the oil recovery wing passage is communicated with the side opening of unidirectional valve ball bottom; In the centre bore of check valve body middle part, a shutoff spool is arranged, on the sidewall of check valve body middle part, the product of joining passage is arranged, join that to produce passage relative with the shutoff spool; Join and produce passage and be communicated with annular space between check valve body and the top connection; Levels bit string circulation passage is communicated with annular space between check valve body and the top connection; Be connected with a connecting rod in the upper end of shutoff spool, the upper end of connecting rod connects the output shaft of motor reducer, and motor reducer is fixed on the upper end of check valve body; Top at motor reducer is fixed with on-off controller, is fixed with battery on the top of on-off controller, between battery and the on-off controller and with the motor of motor reducer between have lead to be connected.The effect of unidirectional valve ball is when suppressing on ground, and unidirectional valve ball is closed, and liquid that can not gets into oil reservoir, can not damage oil reservoir.The opening and close of shutoff spool can be realized regulating and joined product; On-off controller control motor reducer reaches control shutoff spool, thus adjustment join produce passage open or close extent.
For production wells downforce information, on on-off controller, be fixed with pressure gauge.
The beneficial effect of the utility model: the utility model oil well is used bottom hole production allocator; Can not only accomplish processes such as layering water detection, water blockoff and regulating multi-zone production rate with the water detecting and plugging pipe column realization combining one-trip string of giving up; And suppress flexible realization downhole deployment through the ground water filling and move, accomplish Multistage Control to the output passage of layer position.Need not the lower tubular column operation, construction cost is low, have simple to operate, reliable operation, success rate advantages of higher.Accomplish the Multistage Control of the output passage of oil well layer position.
