Description
Technical field
The utility model relates to the oil well technical field, being particularly related to the special tool tubing string that the Oil/gas Well downhole hydraulic sprays the fracture acidizing construction, is that a kind of oil pipe that carries out Oil/gas Well multistage perforation and fracture acidizing stimulation treatment drags hydraulic jetting fracturing acidifying tool tubular column.
Background technology
Continuous probing along with domestic high temperature high pressure deep well, the particularly exploration and development of Tarim Oilfield deep-well, well depth reaches 5000～7000m, belong to deep-well, ultradeep well, also have simultaneously the characteristics that the zone is wide, structure is many, the reservoir span is large, and payzone mostly to could obtain industrial production capacity through the multistage transformation.And at present fixed tubular column injection acid fracturing operating tool string is the single operating tool string, a tubing string is lowered to can not realize more multi-layered section transformation, separate zone stimulation is subject to the limitation of segments, can not finish and carry multistage hydraulic jetting fracturing acidizing treatment on the oil pipe, therefore need a kind of down-hole string structure of proposing the acidifying of oil pipe multistage hydraulic jetting fracturing on the not kill-job device that is specifically designed to of design.
The utility model content
The purpose of this utility model is: provide a kind of oil pipe to drag hydraulic jetting fracturing acidifying tool tubular column, the pressure energy of highly pressurised liquid is converted into kinetic energy, adopt and carry oil pipe hydraulic jetting fracturing acidifying tool tubular column string on the not kill-job device, carry out continuously multi-injection acid fracturing operation.
The technical solution adopted in the utility model is: oil pipe drags hydraulic jetting fracturing acidifying tool tubular column, comprises that tubing nipple, heavy wall tubing, the 3rd X-type are located in joint, testing valve, the second X-type and are located in joint, oil pipe, the dark pipe nipple in school, the first X-type and are located in joint, spray gun group, lower end spray gun group, ball-and-seat, screen casing and guide shoe.It is characterized in that: tubing nipple is connected to well head, heavy wall tubing is threaded in the lower end of tubing nipple, the lower end of heavy wall tubing the 3rd X-type that is threaded is located in joint, the 3rd X-type is located in the lower end screw thread connecting test valve of joint, the lower end of testing valve connects the second X-type by heavy wall tubing and is located in joint, the second X-type is located in the lower end screw thread connected pipes of joint, the lower end of the oil pipe dark pipe nipple in school that is threaded, and the lower end of the dark pipe nipple in school first X-type that is threaded is located in joint; The lower end of being located in joint at the first X-type connects 1～5 spray gun group, connects by oil pipe between each spray gun group; Lower end 1～5 spray gun group connects lower end spray gun group; Lower end spray gun group is comprised of the first spray gun and the first centralizer, and the lower end of the first spray gun is threaded in the first centralizer; Connect ball-and-seat in the bottom of lower end spray gun group, the lower end of the ball-and-seat screen casing that is threaded, the lower end of the screen casing guide shoe that is threaded.
Described spray gun group is comprised of spray gun, sleeve base and centralizer, and annexation is from top to bottom: the lower end of spray gun connects sleeve base, and the lower end of sleeve base connects centralizer.
The summary oil pipe drags the use procedure of hydraulic jetting fracturing acidifying tool tubular column.Consult Fig. 1.Before the tool tubular column, in sleeve pipe 1, be lowered to first oil pipe and arrive the Oil/gas Well shaft bottom under the construction operation; With at least two weeks of water flushing, play flowline.Above-mentioned tool tubular column is connected down Oil/gas Well sleeve pipe 1 interior certain depth position, and each spray gun is aimed at the oil-gas Layer that needs transformation.Then will be transported to the highly pressurised liquid of abrasive material on the spray gun of down-hole with fracturing unit by the ground connecting line, spray gun is assembled the pressure energy of highly pressurised liquid and is converted into kinetic energy, to obtain maximum jet impact force, act on and cut on down-hole casing and the rock or fragmentation, formation runs through sleeve pipe duct or small-sized crack, then continue to utilize fracturing unit by the ground connecting line acid solution or fracturing fluid to be transported on the downhole hydraulic spraycan, oil-gas Layer is carried out pressure break or acidifying transformation.After finishing following one section construction operation, with carrying oil pipe on the not kill-job device spraycan is aimed at the oil-gas Layer that another section needs transformation, carry out as stated above pressure break or acidifying transformation, until finish construction operation.
The beneficial effects of the utility model: the utility model oil pipe drags hydraulic jetting fracturing acidifying tool tubular column, the hydrajet tool that arranges consists of for many group spray guns add sleeve base, by the diverse location of opening spray gun the construction target zone is implemented the operation of jetting acid fracturing, utilize different spray guns on the ground pitching switching tools tubing string, realize that each spray gun can both implement the multi-injection acid fracturing; The testing valve that arranges is positioned at the tubing string middle and upper part, on connect X-type and be located in joint, the unlatching of testing valve realizes the control of oil pipe internal pressure, drags oil pipe by not kill-job device; The tubing nipple group that arranges is regulated the length of oil pipe short circuit group in advance according to the position of construction interval, spray gun is dragged to the position of design.This tool tubular column structure connection is convenient, and function is complete, has brought into play in maximum efficiency the multistage acid fracturing effect of spraycan acid fracturing.Present on-the-spot ten wells on probation of this tool tubular column, technique is efficient 100%, successful behind the acid fracturing.
