摘要： A predetermined condition in a fluid-filled wellbore system can be detected by generating at least one sound in the wellbore system in response to the condition, such that a detectable change is created in some characteristic of the emitted sound, and detecting the at least one sound and the change, the detection being indicative that the predetermined condition has occurred. Equipment for facilitating detection of the condition can include a trigger operable in response to the condition; a generator operable to emit sound in the borehole and to create a detectable change in some characteristic of the emitted sound in response to the trigger; and at least one sensor operable to monitor the sound and detect the change, the detection being indicative that the predetermined condition has occurred. It is also possible to estimate a value of a property of a fluid-filled wellbore system. This can be accomplished by recording data including at least one of pressure and rate of flow at one or more locations in the wellbore system, and then estimating the value of the property by employing a model for predicting at least one of pressure and rate of flow dependent upon parameters detailing at least one of wellbore system geometry, viscoacoustic properties of the fluid and entrained solids contained in the wellbore system, locations of boundaries and entrained solids, and characteristics and locations of disturbances to pressure and flow in the wellbore system, in order to determine a best prediction of some attribute of the recorded data.

摘要： Tubewaves are used to transmit an indication of the depth at which a condition is detected in a well. In particular, the depth is calculated based on the difference in arrival time at the surface of a first tubewave which propagates directly upward in the borehole and a second tubewave which initially travels downward and is then reflected upward. The tubewaves may be generated by a canister designed to implode at a certain pressure. After being introduced into the flowline at an above ground inlet, the canister is carried downhole by gravity and the fluid being pumped. When the canister reaches a depth at which its pressure tolerance is exceeded, it implodes and generates the tubewaves. An analyzer at the surface detects the tubewaves with a hydrophone array and generates a pressure versus depth profile of the well, i.e., one data point for each implosion. Canisters may be acoustically tagged by controlling volume and orifice size in order to generate tubewaves having particular frequency and amplitude characteristics. Canisters may also be configured to produce multiple implosions, e.g., one implosion at each of a selection of different pressures. Canisters may also be equipped with triggering and arming mechanisms, and may generate tubewaves in response to conditions other than a particular pressure.
摘要翻译：涡卷用于传输在井中检测到条件的深度的指示。特别地，深度是基于在井眼中直接向上传播的第一管风管的表面到达时间的差异以及最初向下行进并然后被向上反射的第二管道涡流来计算的。管道可以由设计成在一定压力下膨胀的罐产生。在引入到地面入口的流线之后，通过重力将罐承载在井下，并且泵送流体。当罐达到超过其压力公差的深度时，它会打开并产生管道。表面上的分析仪用水听器阵列检测波音管，并产生井的压力与深度分布，即每个内爆的一个数据点。为了产生具有特定的频率和振幅特性的波管，可以通过控制体积和孔口尺寸来将气囊进行声学标记。罐也可以被配置为产生多个内爆，例如在不同压力的选择中的每一个处产生一个内爆。罐也可以配备触发和布防机构，并且可以响应于特定压力以外的条件而产生管道。

摘要： A method for preparing a formation surrounding a wellbore to bear hydrocarbons through a borehole is disclosed. In one step, a bottomhole assembly is inserted into the borehole. The formation is drilled with the bottomhole assembly. The formation may be characterized with logging tools, probes, sensors, seismic system and/or the like to create first information. One or more fractures are placed in the formation without removal of the bottomhole assembly from the wellbore. Further, continuous drilling of the formation is performed with the bottomhole assembly after/during placing the fractures. Further characterizing of the formation with the probes, sensors/systems or the like is performed to produce second information. Another fracture is placed with feedback from the second information. Repeating the drilling, characterizing and placing of fractures as necessary during the formation preparing process.

摘要： A method of providing a viscous emulsion at a subterranean location accessible via a wellbore, begins by providing an aqueous/aqueous emulsion comprising two aqueous solutions which, at surface temperature and pressure, are able to co-exist as separate aqueous phases in contact with each other. The two phases contain respective solutes which are sufficiently incompatible that they cause phase separation. The dispersed phase is rich in one solute, which may be a thickening polymer, while continuous phase is rich in a second solute, which may comprise surfactant. A hydrophobic liquid is dispersed in this emulsion to become the dispersed phase of a viscous emulsion whose continuous phase is provided by the aqueous/aqueous emulsion. The hydrophobic liquid and the aqueous/aqueous emulsion may be pumped separately down the wellbore to the subterranean location, and allowed to mix there so as to form the viscous emulsion at the subterranean location. On mixing, surfactant from the aqueous/aqueous emulsion may migrate to the oil/water interface, allowing the aqueous phases to become one phase with the result that the emulsion is further thickened by any thickening polymer in its composition. Even more thickening can be achieved by crosslinking the thickening polymer.

摘要： It was found that the addition of polymers to viscoelastic surfactant base system allows to adjust the rheological properties of the base fluid. Depending in particular on one side of the ratio of the concentration of added polymer and the concentration of viscoelastic surfactant and on the other side of the molecular weight of the added polymer, the same polymer - or the same type of polymer - may perform different functions such as viscosity enhancer, viscosity breaker or viscosity-recovery enhancer.

摘要： Methods for treating subterranean wells in which the producing formation is a carbonate comprise preparing a treatment fluid comprising either: (a) an aqueous solution of a multivalent-cation reacting polymer; (b) a solution comprising a fatty acid and an ethanolamine; (c) an aqueous acidic solution of one or more compounds whose calcium salts are insoluble; or (d) an aqueous solution comprising urea or alkane derivatives thereof or both and polyvinylpyrrolidone (PVP). The treatment fluid is placed in the well such that the solution contacts the carbonate formation at a pressure lower than the fracturing pressure. The treatment fluid is allowed to react with the carbonate formation, thereby depositing a film onto the formation surface or part of the formation surface.
