Abstract
The utility model relates to the technical field of borehole operation of oil-water wells, in particular to an absorption well sand washing tool. The tool is composed of an upper cup packer, a lower cup pacer and an adaptor. The upper cup packer comprises an upper connector I and an upper tube body I, the upper tube body I is designed at the lower end of the upper connector I, a central pipe I is designed at the lower end of the upper tube body I, a lower tube body I is connected with the lower end of the central pipe I, a lower connector I is designed at the lower end of the lower tube body I, and the central pipe I is sleeved with a cup seal I. The absorption well sand washing tool achieves the economic efficiencies that sand washing operation is conducted without leaking stoppage of a severe absorption well, the sand washing effect is good, an oil layer is protected, the actual production effect is improved, production cost is saved, and high economic efficiency is created. The shortcoming that the sand washing effect is not ideal after leakage stoppage of the severe absorption well is overcome.
Description
Technical field:
The utility model relates to a kind of oil-water well underground work technical field, particularly a kind of absorption well sand flushing instrument.
Background technology:
At present the oil-water well phenomenon of shaking out is day by day serious, all can take to visit the flow process of sand, sand washing in operation process.The long-pending sand in shaft bottom can also be normally gone out in the region that is normal pressure at strata pressure, but because block pressure is extremely unbalanced, the region of serious leakage in debt on stratum, sand washing often occurs not to be returned, drag for the situation that sand is invalid, after application leak stopping, sand washing effect is all undesirable, cannot change the situation that shaft bottom sand buries oil reservoir, has a strong impact on oil well output.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of absorption well sand flushing instrument, and this device has been realized the not leak stopping of severe leakage well and carried out sand washing operation, and sand washing is effective, and protection oil reservoir, improves production actual effect, saves production cost, and creates higher economic benefit.Overcome the undesirable deficiency of sand washing effect after the leak stopping of existing severe leakage well.
Technical solution adopted in the utility model is: a kind of absorption well sand flushing instrument, is comprised of upper cup packer, down cup packer and crossover sub; Upper cup packer comprises top connection I and upper shell I, top connection I lower end is designed with upper shell I, and upper shell I lower end is designed with central tube I, and central tube I lower end connects lower shell I, lower shell I lower end is designed with lower contact I, is set with leather cup envelope I in central tube I; Down cup packer comprises top connection II and upper shell II, top connection II lower end is designed with upper shell II, and upper shell II lower end connects central tube II, and central tube II lower end is designed with lower shell II, lower shell II lower end is designed with lower contact II, is set with leather cup envelope II in central tube II; Crossover sub comprises top connection III, and top connection III lower end is designed with diameter 48mm oil connection, and connection diameter 89mm lower contact outside top connection III, has a plurality of circulations water hole on diameter 89mm lower contact sidewall; Top connection III upper end connects sand-flushing pipe column, diameter 89mm lower contact lower end connects top connection I, diameter 48mm oil connection lower end connection diameter 48mm oil pipe, lower contact I lower end connection diameter 89mm oil pipe, diameter 89mm oil pipe lower end connects top connection II, lower contact II lower end connection diameter 89mm tubing nipple.
The beneficial effects of the utility model are: the utility model has been realized the not leak stopping of severe leakage well and carried out sand washing operation, and sand washing is effective, and protection oil reservoir, improves production actual effect, saves production cost, and creates higher economic benefit.
Accompanying drawing explanation:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is the structural representation of upper cup packer.
