Definitions
- the device is not required to infer the type of fluid entering the borehole, as preferred embodiments of the invention are sensitive only to conductive fluids.
- the measurement sensor loop has no moving parts, as in some prior art logging instruments that comprise spinners, for example.
- the sensor loop has no threshold fluid velocity below which the measurement registers no flow; thus the sensor loop will sense even a small fluid flow.
- Preferred embodiments of the present invention provide a direct measurement of the information that must generally be inferred by production engineers, that is, where water is entering the borehole.
- FIG. 4 A shows a view of the same items of Fig. 3 from outside the casing looking radially inward;
- Preferred embodiments of the present invention eliminate these problems in the prior art by directly measuring water inflow or outflow through the borehole or casing wall.
- Preferred embodiments of the present invention may provide the depths and rates of water inflow or outflow. Almost all inflow or outflow is one phase, and so the flow is measured before it can combine into complex flow patterns with other phases.
- Preferred embodiments of the present invention are thus insensitive to the complex multiphase flow patterns found inside the wellbore.
- Preferred embodiments of the present invention also are sensitive to only lateral water flow into or out of the wellbore, and are not sensitive to water flow up or down inside the wellbore.
- FIG. 5 shows the fixed force arms 119 coupled to one end of the tool body 101.
- the force arms 119 at one end of the logging tool 140 are fixed firmly to the tool body 101 to maintain the two side arms 102/103 and the tool body 101 in one plane.
- the force arms 119 provide an outward force to force the side arms 102/103 against the inner wall of the casing 11 lb.
- the outward force may be achieved from the elasticity of the metal force arms 119, or from spring loading or other mechanisms, for example.
- the electrodes 129 are preferably spaced equidistant from one another, at regular spacings, with each spacing distance preferably being somewhat about or less than the diameter of a perforation hole 112 (shown in Fig. 8A). Electrodes 129 are contiguous to each other and ring the entire sensor loop 108 to cover the full circumference of the sensor loop 108 and thus the full interior of the casing 111b wall. One electrode 129 can act as the right electrode for a pair of electrodes and also simultaneously act as the left electrode for the next adjacent pair, so that a series of substantially equally spaced electrodes 129 exists at the surface of the sensor loop 108. These electrodes 129 are preferably coupled in series to each other with a high value resistor (shown in Figure 9) between each.
- a high value resistor shown in Figure 9
- the magnetic field 128 is alternating rather than constant to achieve optimum logging results.
- An alternating magnetic field minimizes electrode 129 polarization effects and also minimizes effects of voltages induced by complex chemical and other processes.
- an alternating electrical current may be applied to the coils to obtain an alternating magnetic field 128.
- FIG. 9 shows a schematic of some electrical components within the sensor loop 108.
- the device is not sensitive to the complex flow regimes in the center of the wellbore, because the device measures the flow as it enters the wellbore along the wall and before it enters into the complex flow regimes in the wellbore center.
- the device is not required to infer the cause of changes in above and below readings.
- the novel logging device directly senses water entering or leaving the wellbore.
- the device is not required to infer the type of fluid entered the borehole, as preferred embodiments of the invention are sensitive only to water.
