Abstract
The invention discloses an underground storage type flow and water content monitor which is designed for quickly and accurately finding water at long horizontal well sections and carrying out production acquisition tests. An oil pipe connection thread is arranged at the bottom end of a base of the monitor, a radial liquid inlet hole and an axial liquid through hole which are formed in the lateral wall of the base form a bridge type channel, and a hole in the upper end of the base is connected with an outer cylinder through a connector. A turbine flowmeter, an array water holdup meter, a check valve set, a circuit control board, a communication board and a battery are connected in the outer cylinder from bottom to top, a pressure gauge and a thermometer are arranged on a check valve set base, and a liquid outlet hole is formed in the lateral wall of the outer cylinder, between the check valve set and the circuit control board. The monitor can be used in a multi-stage mode, the quantity of stages is not limited, quick water exploration and flow and water content monitoring can be carried out in a subsection mode in each layer section of the long horizontal well sections ranging from 15 sections to 20 sections by lowering a tubular column for one time, operation procedures on site can be simplified, labor intensity can be reduced, the water exploration test period can be shortened, and water exploration accuracy can be improved.
Description
Technical field
The present invention relates to a kind of down-hole storage type flow and moisture-content monitoring instrument, relate to oil well delamination and ask product, water detection and manometric technique field.
Background technology
At present, sectionalized water-exploration testing pipe column of casing well-completion horizontal well adopts each interval of intelligent switch device timing controlled to produce, chemically examined by ground and analyze each section moisture, judge water layer.The each interval of this technique produces 10 days, and the water detection cycle is long, has a strong impact on produced on-site progress; Ground field sampling affects by sleety weather, and the sampling of every section of fluid is incomplete, inaccurate, accurately cannot judge water exit position; Need manual sampling every day, send chemical laboratory to analyze, and every section singly to be measured liquid measure, significantly increases workload.
Also have a kind of relevant production profile comprehensive logging instrument in addition, be mainly used in recording the total flow of pit shaft in a certain section and moisture data, obtain each interval data by Calculation of the shunted current.The problem of this instrument is that error is larger.
Summary of the invention
The object of the present invention is to provide a kind of down-hole storage type flow and moisture-content monitoring instrument, to realize quick, the accurate water detection of long net horizontal section and to ask product test.
Concrete technology contents of the present invention is as follows:
This monitor base bottom is provided with oil pipe connecting thread; Inlet opening radial on base side wall and axial liquid pass hole form passageway bridge; Base upper end hole is connected by connector with urceolus; Connect turbine flowmeter, array water cut meter, ball-and-seat group, circuit control panel, communication board and battery in urceolus from bottom to top, ball-and-seat group base is provided with pressure and thermometer, and the outer tube side wall between ball-and-seat group and circuit control panel is provided with fluid hole.
This monitor can multistagely use, and progression is unrestricted, can realize the long net horizontal section of one-trip string (15-20 section) each interval segmentation and monitor flow and moisture quick water detection simultaneously, field operation program can be simplified, reduce labour intensity, shorten water detection test period, improve water detection accuracy.
Accompanying drawing explanation
Fig. 1 is down-hole storage type flow and moisture-content monitoring instrument structural representation.
Detailed description of the invention
Embodiment:
With reference to Fig. 1, embodiments of the invention are further illustrated:
This monitor comprises base 1, inlet opening 2, liquid pass hole 3, connector 4, urceolus 5, turbine flowmeter 6, array water cut meter 7, pressure and thermometer 8, ball-and-seat group 9, circuit control panel 11, communication board 12 and battery 13:
Base 1 bottom is provided with oil pipe connecting thread; Inlet opening 2 radial on base 1 sidewall and axial liquid pass hole 3 form passageway bridge; Base 1 upper end hole and urceolus 5 are threaded by connector 4; Turbine flowmeter 6, array water cut meter 7, ball-and-seat group 9, circuit control panel 11, communication board 12 and battery 13 is threaded connection from bottom to top in urceolus 5, ball-and-seat group 9 base is provided with pressure and thermometer 8, and urceolus 5 sidewall between ball-and-seat group 9 and circuit control panel 11 is provided with fluid hole 10.
The present embodiment monitor implements segmentation water detection test in Y horizontal well, well depth 3200m, extended horizontal depth 800m, and perforation completion is six sections, and casing inner diameter is 124.26mm:
First, the acquisition time carrying out the data such as flow, moisture, pressure, temperature in the face of six monitors on ground is arranged, and then will be drilled into the pay interval of each correspondence of horizontal well under it, adopts packer card to seal between each interval.When ground oil pumper is produced, the fluid of each interval will flow to pit shaft by stratum.When fluid is through being located at the monitor of each interval, fluid enters from inlet opening 2, after liquid pass hole 3, turbine flowmeter 6 and array water cut meter 7, flows out from fluid hole 10, and around here, the data such as the flow of fluid, moisture, pressure and temperature are collected and store.When production reaches plateau in 5-6 days, trip out monitor, playback and analysis storage data.
