Abstract
The utility model provides an integrated pipe string for looking for water proofing, water plugging, acidification and plugging breaking, and is applied in an oilwell for looking for water proofing, water plugging, acidification and plugging breaking. A rod type pump seat clamp is connected to the lower part of an oil pipe; a backwashing valve is connected to the lower part of the rod pump seat clamp; an upper packer is connected to the lower part of the backwashing valve; a sieve tube is connected to the lower part of the upper packer; a lower packer is connected to the lower part of the sieve tube; a hydraulic anchor is connected to the lower part of the lower packer; and a screwed plug is connected to the lower part of the hydraulic anchor. The utility model has the effect that the pipe string can be put into the oilwell in one step, and the operation of looking for water proofing, water plugging, acidification and plugging breaking is fulfilled at the same time. Therefore, the utility model has the advantages that the procedure continuity is high; more than a half of well repair procedures are reduced; operation cost of like measures is reduced; the water source finding accuracy is high; the measure pertinence is high; and the measure effect and the effective rate are remarkably improved.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of downhole production tubing string is a kind of special-purpose tubing string in down-hole that water proof, water blockoff, acidifying, broken block operation are looked in the layering of oilfield multiple zone that is applied to.
Background technology
Oilfield often has a plurality of oil reservoirs.At a bite well a plurality of oil reservoirs are arranged, and when adopting the insert pump exploitation, need find out water layer, oil reservoir, and the shutoff water layer.Need at first adopt two parameter testing technology that oil reservoir is tested, try to achieve the liquid measure and the moisture content of each oil reservoir, then lower tubular column water proof or water blockoff and de-plugging; Perhaps directly take to squeeze various water shutoff agents and acidification blocking remover.These kinds technology has distinct disadvantage: liquid measure that two parameter testings obtain and moisture content and actual coincidence rate are extremely low, cause the well workover cycle long, operation is many, specific aim is poor, the water proof after the well workover, water blockoff, yield-increasing technique DeGrain.
The utility model content
The purpose of this utility model is: provide a kind of integral type to look for water proof, water blockoff, acidifying, broken block tubing string, realize improving the accuracy of two parameter testings, the coincidence rate of raising well workover measure and specific aim and effect are efficient, minimizing measure, kill-job working solution consumption.
The technical solution adopted in the utility model is: integral type is looked for water proof, water blockoff, acidifying, broken block tubing string, be connected with rod-type pump seat card in the bottom of oil pipe, bottom at rod-type pump seat card is connected with backwash valve, bottom in backwash valve is connected with upper packer, bottom at upper packer is connected with screen casing, bottom at screen casing is connected with lower packet, is connected with hydraulic anchor in the bottom of lower packet, is connected with plug in the bottom of hydraulic anchor.
What described upper packer adopted is the Y111-115 packer; What lower packet adopted is the Y211-115 packer.Lower packet is that rotation sets the formula packer.
When needing to recover the oil after finishing test, in oil pipe and on rod-type pump seat card top insert pump is arranged, the top of insert pump is connected with sucker rod.
The summary integral type is looked for being lowered to and use of water proof, water blockoff, acidifying, broken block tubing string.Consult Fig. 1.With this pipe string combination G.I.H predetermined level, insert pump 5 is not lowered to earlier.In layer look for water proof water blockoff, acidifying, broken block from top to bottom.Set because lower packet 10 is rotations, behind the precalculated position, earlier lower packet 10 rotations are set and pressure testing.After setting and supporting, transfer tubing string, upper packer 8 is also set to predetermined weight.The sealing of sleeve pipe 1 is surveyed in examination then.The required like this layer position of water proof and water blockoff acidifying of looking for just sealed by card.Descend simultaneously the production of recovering the oil of insert pump 5 and sucker rod 4.Try to achieve several days output and moisture content according to the oil well production situation.According to the situation of output and moisture content, determine whether to take water proof, water blockoff or acidifying and other broken block measure.After determining measure, utilization need not be moved the characteristics of tubing string well workover, as long as rod type pump 10 proposes, motionless other tubing string just can carry out various measure operations.Need change layer after while, one deck measure operation finished and carry out measure, only need to carry just energy deblocking, transfer tubing string again and set to another oil reservoir.Repeating above-mentioned operation can finish the oil recovery of many wells section, look for water proof, water blockoff, acidifying, broken block technological measure.
The beneficial effects of the utility model: integral type is looked for water proof, water blockoff, acidifying, broken block tubing string, and running string of energy is finished simultaneously and looked for water proof, water blockoff, acidifying, broken block operation.The operation continuity is strong, reduces workover operation over half.Reduce similar measure operating cost; Water detection data accuracy rate height, measure is with strong points; Measure effect and efficient raising are obvious.
