摘要： Gas influx into a wellbore, called A "kick", is detected by two different, yet complementary methods during active drilling of the borehole. The first method is based upon the existence of standing wave patterns generated by pressure oscillations of the drilling rig mud pumps. Such standing wave patterns form time sequences of maximum and minima as a gas slug moves upwardly in the annulus. The time between such peaks of such oscillations is measured and forms the basis for generation of one first kick signal. A continuous increase in the phase between annulus and drill string standing waves forms the basis for another standing wave kick signal. The second method uses acoustic signals from a downhole source near the bottom of the borehole which are transmitted at different speeds in the annulus mud and in the interior drill string mud, where the annulus mud may be gas cut. A difference in arrival time between the signals is determined, and if large enough, causes a second kick signal to be generated. A third method may be used where at least two drilling pumps are used in the drilling system. Such method determines the total travel time, from standpipe to drill string and up the annulus, of a beat frequency pressure wave caused by slightly different frequencies of the two pumps. An alarm signal is generated if the total travel time is greater than a computed threshold.
摘要翻译：在井眼的主动钻井过程中，通过两种不同但又互补的方法来检测气体涌入井眼，称为“踢”。第一种方法是基于钻机泥浆泵的压力振荡产生的驻波模式的存在。当气囊在环形空间中向上移动时，这种驻波图案形成最大和最小的时间序列。测量这种振荡的这种峰值之间的时间，并且形成产生一个第一踢脚信号的基础。环形和钻柱驻波之间的相位的连续增加是另一个驻波起搏信号的基础。第二种方法使用来自钻孔底部附近的井下源的声学信号，其在环形泥浆和内部钻柱泥浆中以不同的速度传播，其中环形泥浆可以被气体切割。确定信号之间的到达时间的差异，并且如果足够大，则产生第二反转信号。可以使用在钻井系统中使用至少两个钻井泵的第三种方法。这种方法确定了由两个泵的稍微不同的频率引起的节拍频率压力波的总行驶时间，从立管到钻柱和环向上。如果总行程时间大于计算的阈值，则会产生报警信号。

摘要： The invention is a non-intrusive system for measuring the flow rates of insulating or conducting fluids in conduits. It results from the combination of an electromagnetic flowmeter, operating with conducting fluids, and of a triboelectric noise cross-correlation flowmeter, operating with insulating fluids. The system is equipped with a non-intrusive device for measuring fluid conductivity. The electronic signal processing unit uses the conductivity value to decide which of the two sensors is providing a signal effectively representing the fluid flow rate. The electromagnetic flowmeter may use electrodes of small cross-section in contact with the fluid or, more advantageously, it may be of the capacitive type using larger section electrodes isolated from the fluid.

摘要： A logging tool having a plurality of different sensor types having close spacings mounted on an articulated or extendible pad, a sleeve, a mandrel, a stabilizer, or some combination of those is provided and used to make measurements in a wellbore in a single logging run. Those measurements are used to create images of the wellbore and the images are used to deduce the local geology, optimize well placement, perform geomechanical investigation, optimize drilling operations, and perform formation evaluation. The logging tool includes a processor capable of making those measurements, creating those images, performing those operations, and making those determinations. The plurality of different sensors may be one or more resistivity sensors, dielectric sensors, acoustic sensors, ultrasonic sensors, caliper sensors, nuclear magnetic resonance sensors, natural spectral gamma ray sensors, spectroscopic sensors, cross-section capture sensors, and nuclear sensors, and they may be “plug-and-play” sensors.
