Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly horizontal well production tubing string is a kind of flow string technology of controlling water ridge inlet well segmentation control water at the bottom of the bottom water reservoir.
Background technology
In the oilfield horizontal well Development Practice, the water ridge advances to cause the fast problem of well water rising perplexing the oil field development worker always at the bottom of the bottom water reservoir, well water rises rapidly behind the bottom-water breakthrough, enter high water-cut stage very soon, cause oil output per well sharply to descend, and the accumulation extraction oil mass of this moment is not high; And the later stage that is that all right technically is ripe at the measures such as water blockoff of horizontal well, and fund input is big, period of validity is short.Therefore, seek horizontal well and effectively control or delay end water ridge and advance the oil production technology technology, thus the rate of water cut increase of controlling level well, and it is very necessary to increase oil output per well.
At present, for the horizontal well development bottom water reservoir mainly be based on control wellbore trace and keep away measures such as water height, oriented perforating control end awl speed waterborne, the production of control oil well production pressure reduction to increase horizontal segment.Correlation technique has: selectivity production technique, segmenting perforating segmentation production technique etc., but development effectiveness is not ideal, mainly has following problem:
1, to the bottom water reservoir that shakes out, adopt sieve tube completion, full well or segmentation exploitation, pressure distribution is uneven on horizontal segment, and the contribution of horizontal segment production fluid is unbalanced, lacks in addition end water water ridge section forecasting research and effectively completion oil recovery measure, though cause reservoir sand to be blocked, but the very fast water logging of oil well, water-free oil production period is short, and the individual well cumulative recovery is low.
2, adopt sleeve pipe segmenting perforating completion, owing to be subjected to the restriction of present perforation equipment, horizontal well becomes hole secret skill art can not reach the ideal designs result, and fund input is significantly risen.
3, on the fragmentation technique of oil well, mainly adopt packer or bridging plug to realize the separation of horizontal segment, complex process, the operating expenses height, and also it is big that the horizontal segment that has sealed is reactivated the measure difficulty.
The utility model content
The purpose of this utility model is: a kind of flow string of horizontal well in segments control water is provided, makes that the water inlet of water ridge is eased and effectively control the well reservoir development of finally improving the standard effect at the bottom of the horizontal well.
The technical solution adopted in the utility model is: the flow string of horizontal well in segments control water, mainly form by screen casing tubing string and oil pipe tubing string, the oil pipe tubing string is characterized in that in the screen casing tubing string: the lower end that the screen casing tubing string is suspended on production string by tail tube hanging packer.The screen casing tubing string is to be connected into by screen casing and blind pipe, and is connected with 2～4 groups meets water and meet oily swell packers in the middle of screen casing and blind pipe, meets and is fixed with the layering sealing drum in the oily swell packers meeting water.Be connected with well-flushing sealing drum, well-flushing circulating valve and well-flushing guide shoe in the bottom of screen casing tubing string.The oil pipe tubing string is that oil pipe is connected with the plug-in type sealer from top to bottom, and plug-in type sealer lower end connects oil pipe, and the bottom of oil pipe is connected with ported sub, is connected with oil pipe and plug in the lower end of ported sub.
The permanent position of described plug-in type sealer is at the top of screen casing tubing string.
On the screen casing tubing string, be fixed with and meet water and meet oily swell packers, behind the oil and water contact expansible packer inflation, horizontal hole is divided into relatively not UNICOM's section of recovering the oil.Utilize oil pipe tubing string ported sub to be separately fixed at relatively not in the oil recovery section of UNICOM, can realize the exploitation of any horizontal segment or close and adopt, realization sand control, oil recovery are integrated.
The beneficial effects of the utility model: the flow string of the utility model horizontal well in segments control water, can realize the exploitation of any horizontal segment or close and adopt, realize sand control, recover the oil integrated.1 and the full well section of light water horizontal well produce relatively, horizontal segment exploitation pressure is balance more, water-free oil production period increases, rate of water cut increase is controlled; 2, the segmentation that can realize three sections is recovered the oil, and divides the segment process advanced person, is easy to construction, is easy to realize sealing the utilization again of well section; 3 and perforation completion segmentation oil recovery technique in the past relatively, reduced the shaft building investment and the later stage operating cost of oil well.On-the-spot contrast test shows has slowed down end lifting speed waterborne.
Description of drawings
Fig. 1 is the structural profile schematic diagram of flow string in well of the utility model horizontal well in segments control water.Be to have two to meet water and meet oily swell packers 7 on the screen casing tubing string, horizontal hole is divided into three sections controls, the schematic diagram that recovers the oil from interlude.
