Description
Technical field
The utility model relates to oil gas well formation testing technical field, specifically, is the integrated formation testing tubing string of a kind of perforation, test, acidifying and discharge opeing.
Background technology
In the existing oil gas well formation testing testing method, although the testing tool of application of advanced, can obtain data preferably, but can not realize that continuously a large amount of discharge opeings and fixed tubular column carry out large-scale measure operations such as acid fracturing, make to need a large amount of discharge opeings or need Pressure Curve in Oil Testing Well that acidifying transforms replace tubes post again, cause secondary pollution and formation testing test construction period longer easily.So finish the development trend that multinomial formation testing operation is an oil gas well formation testing testing method with one-trip string.
Aspect institutional operation, there is " perforation and APR test " connection to do and " perforation-MFE test-hydraulic jet pump discharge opeing " combination operation process technology with the immediate formation testing technology of the utility model at present.
Oil gas well " perforation with APR test " connection do be exactly packer, APR formation test tool are carried lower going-into-well together with perforating gun by oil pipe or drilling rod at the bottom of, make perforating gun aim at target zone deeply by the well logging school, base sealed packer is isolated target zone and annular space well killing fluid.Testing valve is opened in pressurization earlier to annular space, continues the ignition perforating gun that boosts then.Stratum liquid directly enters operating tool string and tests.After finishing, test trips out construction tool.This technology has solved the danger (when running into high-pressure oil-gas layer, well killing fluid is not enough to equilibrium strata pressure, and blowout takes place probably) that prevents formation contaminant (because target zone and annular space well killing fluid being isolated) and cable perforation before perforation.But the deficiency of technology is: must keep certain pressure, the less stable of its switch well at the oil jacket annular space on the one hand in the process of driving a well.On the other hand, non-the replace tubes post could be realized again from spray-up and need carry out acidifying (or acid fracturing) construction to the stratum time for the heavy oil tested layer of the further discharge opeing of needs or low pressure, has increased workload and easily oil reservoir is polluted.
" perforation-test-hydraulic jet pump discharge opeing " combination operation process technology has realized perforation-MFE test and the integrated formation testing construction of hydraulic pump discharge opeing.Its process unit has added hydraulic jet pump on " perforation and MFE testing combination operation " tubing string.Hydraulic jet pump fluid-discharge technology technology is to inject high voltage power liquid to underground hydraulic pump from ground by oil pipe, when passing through nozzle, trunnion and anemostat, pump in-core high voltage power liquid forms a negative pressuren zone at nozzle and trunnion place, thereby suck and carry stratum liquid, return out ground with power fluid through sleeve pipe, separate and measure.Compare with conventional fluid-discharge technology (fall liquid level, liquid nitrogen discharge opeing or utilize simple discharge opeings such as NAVI pump, screw pump or pumping), can realize continuously, big pressure reduction (but negative pressure is to 3000m), high yield discharge opeing as vaporize water.The stratum there is certain de-plugging effect, thereby understands the true production capacity on stratum.Before discharge opeing, can take to squeeze small-sized measures such as thinner, stratum cleaning agent, return discharge opeing then immediately.The hydraulic pump power fluid can be heated and can be added breakdown of emulsion, viscosity reduction, pour-point depressant, has satisfied high requirement of coagulating the heavy oil wells discharge opeing.The technology shortcoming is: can not realize that 1, motionless test string directly carries out acidifying large-scale modification measures such as (acid fracturings) to test layer, carries out discharge opeing then immediately.2, switch well operating difficulties in inclined shaft and heavy oil wells.3, MFE tester internal diameter is less and be not latus rectum.Can not be lowered on the one hand well testing instrument such as pressure gauge from ground to carrying out the well testing operation below the tester.On the other hand, viscous crude or stratum impurity stop up tester easily and cause test crash during test.
