Abstract
The invention relates to a sand-control matching pipe column for a horizontal well drillable quartz sand filter tube, which is composed of a packer, quartz sand filter tubes, a drillable central tube, a drillable centralizer and a drillable screwed plug. The matching pipe column is characterized in that the drillable central tube is arranged in the casing center of a horizontal well extending to an oil layer and is straightly penetrated through the cross section of a sand-control oil layer, and the packer is arranged at the rear end of the drillable central tube to seal the annular space between the drillable central tube and an oil layer casing; the drillable pipe plug is arranged at the front end of the drillable central tube, a plurality of quartz sand filter tubes are nested on the central tube between the packer and the drillable screwed plug, and the drillable centralizer is arranged between the quartz sand filter tubes. The invention has the advantages that the problems that the replacement of the filter sand tube is difficult, and the obsolescence of the oil well is easily caused are solved.
Description
One, technical field
The present invention relates to a kind of sand control process matched therewith, specifically a kind of horizontal well drillable quartz sand filter tube sand-prevention assorted tubing string.
Two, background technology
Development along with the oil field development technology, the development level well is to reduce the oil field development cost, reduce the area that occupies cultivated land, be convenient to centralized management, improve the field management level and increase the upper important measures of producing of oil, it is the important exploitation measure of Tan Hai oil field and offshore oilfield, because horizontal well well bore to oil reservoir place is that level is stretched to oil reservoir, cross oil reservoir, the perforated hole segment length carries out relatively difficulty of sand control, change relatively difficulty of filter sand, especially at present the metal sand screen of usefulness does not have pliability the external diameter of metal sand screen is larger in addition, obliquely breaks or can pull out out at all once pulling out, and causes workover or scraps; Cause the tremendous economic loss to the oil field.
Three, summary of the invention
The purpose of this invention is to provide the quartzy sand filtration assorted column jacket of a kind of horizontal well drillable, solve the replacing sand screen difficulty that above-mentioned prior art exists, easily cause the problem that oil well is scrapped.
Technical scheme of the present invention is achieved in the following ways:
The present invention is comprised of packer, quartz sand chimney filter, drillable central tube, Drillable stabilizer and drillable plug, it is characterized in that the cover tube hub that stretches to oil reservoir at horizontal well arranges a drillable central tube, direct puncture is crossed the cross section of sand control oil reservoir, drillable central tube rear end is provided with packer, the annular space of packing drillable central tube and production string; Front end arranges a drillable plug, and the central tube cover between packer and drillable plug has several quartz sand chimney filters, is provided with Drillable stabilizer between the quartz sand chimney filter.
The drillable central tube is made as the PVC shape plastic pipe, is provided with male thread or box thread at rearward end and the leading section of drillable central tube, evenly is provided with some pores on the central tube between the screw thread of two ends.
The quartz sand chimney filter is made as cylindrical shape, mixes one by quartz sand and 20: 1 by ratio of weight and the number of copies ratio of phenolic resins colloid, and at 150 ℃ of-160 ℃ of lower die formings, degree of porosity is 5-10 μ m.
Drillable stabilizer is made as cylindrical, and external diameter is slightly less than casing inner diameter, and internal diameter is slightly larger than the central tube diameter, is made by the PVC plastics.
The drillable plug is made by the PVC plastics, and an end is provided with male thread or box thread; One bonds between drillable central tube and Drillable stabilizer and the drillable quartz sand chimney filter.
Compared with the prior art the present invention has the following advantages:
1, the present invention is flexible structure, is set to oil reservoir down easy, and success rate is high.
2, the present invention adopts the drillable material to make, and changes easily, as long as this tubing string is carried out by drilling fluid with bit drills is broken.
3, improved anti-sand coarse aggregate ratio, prevented that sand-proof pipe is stuck in the well, causes the dried-up well disused well.

Five, specific embodiment
For further disclosing technical scheme of the present invention, elaborate by embodiment below in conjunction with Figure of description:
The present invention is comprised of packer 1, quartz sand chimney filter 2, drillable central tube 3, Drillable stabilizer 4 and drillable plug 6, it is characterized in that the cover tube hub that stretches to oil reservoir at horizontal well arranges a drillable central tube, direct puncture is crossed the cross section of sand control oil reservoir, drillable central tube rear end is provided with packer, the annular space of packing drillable central tube and production string; Front end arranges a drillable plug, and the central tube cover between packer and drillable plug has several quartz sand chimney filters, is provided with Drillable stabilizer between the quartz sand chimney filter.The drillable central tube is made as the PVC shape plastic pipe, is provided with male thread or box thread at rearward end and the leading section of central tube, evenly is provided with some pores on the central tube between the screw thread of two ends.
Horizontal well is in normal operation, by sucker rod 7, oil pipe 8, the pumping pipe string that sleeve pipe 9 and oil well pump 10 forms with by packer 1, drillable quartz sand chimney filter 2, drillable central tube 3, Drillable stabilizer 4, the horizontal well drillable quartz sand filter tube sand-prevention tubing string that perforated casing 5 and drillable plug 6 form separates, when sand control pipe stops up or sand controlling result when bad, trip out the sucker rod of pumping pipe string, oil pipe and oil well pump, drill bit with overhaul operating machine grinds the sand control assorted column jacket, carrying out ground with drilling fluid gets final product, as above new sand control assorted column jacket, connect on well workover pipe string, arrive down the design attitude of oil reservoir, trip out well workover pipe string and namely finish the task of changing the quartzy chimney filter sand control of horizontal well drillable assorted column jacket.
