Description
Technical field
The present invention relates to oil-gas exploration technical field, in particular to a kind of electric-controlled intelligent completion measuring and adjusting system and method.
Background technology
In field of petroleum exploitation, for the exploitation of oil well, As time goes on, the problems such as reservoir pressure decline, water ratio rising all make oil well output reduce, and cannot exploit by the petroleum production of design. Therefore, after entering high water-cut stage mining phase, it is necessary to High water cut oil reservoir is taked stifled water measure carry out shutoff, and exploit low waterbearing stratum with the object finally reaching water and oil control, effect is put forward in volume increase. Meanwhile, due to current high temperature high pressure oil gas well, complex structural well, sea and sea, beach oil-gas field, the increasing of horizontal well, conventional completion mode is also constantly challenged by severe oil reservoir situation and envrionment conditions.
In order to overcome the problems referred to above, it is necessary to oil mining process is carried out Precise control, carry out Real-Time Monitoring and control with the Production development to each oil reservoir of oil well, finally realize layer mining, the zonation test of oil well and look for stifled water. Intelligent well completion technology proposes just in this context, and this technology can gather, transmit down-hole occurrence, thus regulated and controled by oil reservoir Production development according to oil well practical condition, it is to increase oil well occurrence. To the mid-90, intelligent well completion technology obtains the application got more and more in oil mining. At present, in layer mining, the zonation test of oil well with look in stifled water etc., mainly contain following several Technology:
1) mechanically driver type, mainly comprise adopt point take out that pump, single tube, individual well are two-tube, proportioning pump, level pressure production mandrel and separate extracting pump hierarchical oil production technology, also comprise simultaneously by under enter to control tubing string each interval underground sliding sleeve carried out switch, it is achieved layering is recovered the oil. But, mechanically driver type layering oil production technology operation technique is complicated, efficiency is lower, and the Production development of each oil reservoir cannot carry out Real-Time Monitoring and control.
2) hydraulic drive type, ground hydraulic pumping plant is connected with each interval underground sliding sleeve by hydraulic power line, to drive underground sliding sleeve to move, it is achieved layering is recovered the oil.But, hydraulic drive type layering oil production technology hydraulic power line number is more, layering Limited Number, cost are higher, and enter under process pipe string, rise complexity, site operation task difficulty is big, deep-well needs high pressure even ultra-high voltage ground pump station, also is difficult to realize the step-less adjustment of flow simultaneously.
3) driven by power formula, mainly refers to by motor, drive mechanism control well low sleeve or oil nozzle change in location, to realize layering oil production method. Such as, under adopting cable power supply and transmission signal control well, electronic valve action realizes layering oil recovery, but, the flow of each interval only can be carried out switch by this kind of mode, cannot realize the step-less adjustment of flow.
4) wave transmission mode, it is adopt cementing truck (or well-flushing car) to be filled by sleeve pipe from well head, carry out " suppress-pressure release-suppress " operation, thus produce pressure instruction waveform, with the switch of derailing switch under control well, realize layering to recover the oil, the shortcoming of this kind of mode is that regulation and control efficiency is low, the Production development of each oil reservoir can not be carried out real-time monitoring, also stepless Flow-rate adjustment cannot be carried out, simultaneously owing to adopting down-hole battery to be powered by derailing switch, therefore it is subject to the constraint of battery life work-ing life.
