Abstract
The process system includes acid treatment or frac-string. Connected to oil pipes, jet pumps and packers put down to well in one shot are utilized in match with acid treatment or frac-string so as to form pipe strings for united operations of acid treatment or frac-string and flowing liquid by jet pump. Pressure gauge and sampler carried by jet pump are put inside oil pipes or drill pipes to fulfill operation of flowing liquid continuously and rapidly. The invention raises work efficiency and prevents pollution from oil layer. Strong suction force provides function of broken down for subterranean formation. The invention is suitable to conditions: well total depth less than 4500m, hole deviation less than and equal to 72 degrees and delivery rate less than and equal to 600m3/d.
Description
Technical field
The present invention relates to be used for residual acid of the row of returning or the of the fracturing fluid process system that disposable operation collection acidifying of oil well acidation or pressure break and discharge opeing or pressure break and discharge opeing are one.
Background technology
At present, modes such as suction, liquid nitrogen, vaporize water discharge opeing are generally adopted in formation acidizing or post-fracturing discharge opeing, and suction easily causes environment pollution, and the liquid nitrogen expense is high high, the vaporize water discharge opeing is dangerous, and above three kinds of modes neither can make discharge opeing carry out continuously and speed slow.
Can be under the situation that does not influence acidifying or pressure break and acidifying or the supporting use of fracturing string, disposable G.I.H forms acidifying or pressure break and joins with the jet pump discharge opeing and makes tubing string.After acidifying or pressure break are intact, can finish its discharge opeing work continuously and fast from input jet pump core (pump core portability pressure gauge and sampler) in the oil pipe (or drilling rod).
Formation acidizing or pressure break and jet pump connection are done the exploitation of technology, it is the process innovation of acidifying (or pressure break) discharge opeing, it is discharge opeing fast continuously, improved operating efficiency, avoided oil layer pollution, and the High Voltage pumping function has good de-plugging effect to the stratum, good economic benefit is arranged, it is applicable to well depth≤4500m, all kinds of oil gas water wells of hole deviation≤72 °.Discharge capacity≤600m
3/ d.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art, and provide a kind of formation acidizing or pressure break and jet pump connection to make the fluid-discharge technology system.
Can take following technical scheme to realize purpose.
Formation acidizing or pressure break and jet pump connection are made the fluid-discharge technology system, comprise acidifying or fracturing string; Also have jet pump, packer, they are connected with oil pipe.
The relative prior art of present technique has following advantage and effect
Can be under the situation that does not influence acidifying or pressure break and acidifying or the supporting use of fracturing string, disposable G.I.H forms acidifying or pressure break and joins with the jet pump discharge opeing and makes tubing string; After acidifying or pressure break are intact, can finish its discharge opeing work continuously and fast from input jet pump core pump core portability pressure gauge in oil pipe or the drilling rod and sampler; Its continuous quick fluid-discharge has improved operating efficiency, avoided oil layer pollution, and the High Voltage pumping function has good de-plugging effect to the stratum, and good economic benefit is arranged; Applicable to well depth≤4500m, all kinds of oil gas water wells of hole deviation≤72 °; Discharge capacity≤600m
3/ d.
Description of drawings
Accompanying drawing is that formation acidizing and jet pump connection are made the fluid-discharge technology system schematic.
The specific embodiment
In conjunction with embodiment technical scheme is described in detail.
Embodiment 1, formation acidizing or pressure break and jet pump connection are made the fluid-discharge technology system, comprise acidifying or fracturing string, and it is characterized in that: also have jet pump 1, packer 2, they are connected with oil pipe 3.
On original acidifying or fracturing string basis, jet pump, packer, ball-and-seat have been increased, when acidifying or pressure break are not carried out, the ball of ball-and-seat does not drop into well, jet pump, packer and ball seat design simultaneously do not influence and inject acid solution or fracturing fluid in well, after treating that acidifying or pressure break are finished, when needing discharge opeing, pitching is taken a seat, throw the jet pump core again, adjust ground high voltage power pump to jet pump work institute to pump pressure and can carry out discharge opeing work.
