Description
Technical field:
The present invention relates to a kind of technology and device that oilfield horizontal well production dynamically reaches the monitoring of well bore engineering state that be used for.
Background technology:
Well logging is a kind of downhole oil gas exploration method, is used to find oil-gas reservoir, assessment oil and gas reserves, output, the dynamic condition of production of monitoring oil gas well and the engineering state of well bore.Conventional logging technique technology adopts cable to carry the mode of downhole instrument, in instrument is gone into the well process, mainly relies on the effect that focuses on gravity certainly of downhole instrument and cable to fall down.This technology is mainly used in the logging operation of straight well or gradient inclined shaft within the specific limits.After the number of degrees of hole deviation surpassed certain limit, because the influence of instrument and cable and wall friction power, instrument can't be transferred to the purpose degree of depth in the well.In recent years, horizontal well has become a ripe applicable technology of oil-gas field development, its cumulative adding of well a few days.Because the exceptional well body structure that horizontal well has, conventional logging method can not be finished test assignment.At present, the horizontal wellbore logging technology adopts two kinds of methods usually, a kind of method is " wet joint " mode, utilize rig or working rig that power is provided, adopt drilling rod or oil pipe that logger is carried out delivered downhole, and utilize mud circulation power to make horizontal well cable butting instrument carry out necessary combination to logger, and realize the electric connection of downhole instrument, logging cable, ground installation, carry out horizontal wellbore logging then.This logging mode needs not only in the entire job process that drilling crew's equipment and personnel are omnidistance to be cooperated, and construction technology complexity, loaded down with trivial details, and long construction period, labour intensity are big, and the risk that various contingencies occur is higher.Another kind method is the tractor mode, utilizes " crawl device " being with tester " to climb " horizontal segment and goes to test." crawl device " is to rely on motor as power, is the rotation of driving wheel by mechanical drive mode with the power conversion of motor, " creeps " in well thereby drive downhole instrument.This mode is because " crawl device " complex structure, and power is limited, and under the complex conditions of down-hole, mechanical breakdown or casing programme change and all can cause the instrument can't operate as normal.Therefore this mode is limited too much, and result of use is relatively poor.
Summary of the invention:
The object of the present invention is to provide and a kind ofly can overcome existing level borehole logging tool technical disadvantages, continuous tube horizontal borehole process that application apparatus is few, simple to operate, efficiency of construction is high and device.
Technical scheme of the present invention is as follows.This kind logging technique technology is to combine with logging technique managing operation technique continuously, promptly utilizes the characteristics of pipe high strength, high tenacity continuously, as the means of delivery of well logging downhole instrument, instrument is sent into the net horizontal section of horizontal well and is tested.Continuously pipe twists on the cylinder, and the continuous rotation by control injection head and cylinder drives removing of continuous pipe, can guarantee that downhole instrument tests continuously.The main device that this kind logging technique technology adopts comprise continuous pipe working rig, continuously pipe, wellhead assembly, continuously pipe be connected with downhole instrument pipe nipple, horizontal well downhole logging instrument device and instrument, well logging numerical control ground system, continuously manage depth system, manage signal transmission system continuously.
Continuously the pipe working rig is the complete implement of a cover, comprises continuous tube injection head, manages devices such as cylinder, jammer, operation control room continuously, and mainly as the loading of continuous pipe and remove power set, pipe is as the means of delivery of well logging downhole instrument continuously.By the interlock of continuous tube injection head and cylinder, drive continuous pipe removing in well.Pipe is connected with downhole instrument continuously, because it has certain rigid, so can drive downhole instrument any position (comprising horizontal segment) continuous motion in well.So just can under the situation of not assisting, independently finish the test assignment of horizontal well by any miscellaneous equipment.
The pipe depth system adopts the coil pipe apparatus that depth transducer is housed continuously, can export and write down the speed that removes of continuous pipe synchronously, in real time, for well-log information provides depth information.
Continuous pipe signal transmission system mainly comprises wears cable, cable collecting ring and downhole instrument head harness in the continuous pipe.
Continuously pipe is connected pipe nipple and will manages continuously with downhole instrument and mate up with downhole instrument, should guarantee the bonding strength requirement, satisfies the transmission requirement of the logger signal of telecommunication again.
The horizontal well downhole tool mainly comprises down-hole tension nipple, flexible pipe nipple and rotating short-knot etc. as the special tool of horizontal wellbore logging.
Well logging numerical control ground system and all kinds of downhole instrument according to the difference of well logging project, are selected corresponding logger as the well logging special equipment.
The continuous pipe that horizontal wellbore logging technology provided by the invention utilization has high strength, a high tenacity is as the means of delivery of well logging downhole instrument, can guarantee that downhole instrument tests under various horizontal well conditions; Because this technology adopts continuously isolated plants such as pipe working rig, not only application apparatus is few, and has characteristics such as mobility is good, easy to operate, efficiency of construction height.Utilize this kind technology and device can guarantee the stability of downhole instrument duty and disposable, it is truer to measure the horizontal well data that obtains, and coincidence rate is higher.
