摘要： The present invention is, in some embodiments directed to methods for optimizing wellbore displacement operations via in situ fluid property assessment/monitoring. By monitoring fluid properties in situ (i.e., downhole), fluid property assessment is direct instead of being inferred. Additionally, wherein such assessment/monitoring is carried out in real time, changes to the displacement fluid can be made "on-the-fly," thereby contributing to an enhancement of the overall efficiency of the method.
摘要翻译：在一些实施例中，本发明涉及通过原位流体性质评估/监测来优化井筒位移操作的方法。通过现场监测流体性质（即井下），流体性质评估是直接的，而不是被推断。此外，其中这种评估/监测是实时进行的，可以“即时”地对位移流体进行改变，从而有助于提高该方法的整体效率。

摘要： A transmitter on a bottomhole assembly (BHA) is used for generating a transient electromagnetic signal in an earth formation. A processor estimates the distance to a resistivity interface using a signal produced by a receiver on the BHA. The transmitter-receiver distance may be less than 1m. The estimation of the distance is done in real time using a thin conductive sheet approximation.

摘要： Systems and methods for determining at least one parameter of a fluid in a well are provided. The system has a downhole system deployable into the well, and sensor elements to measure fluid parameter(s) of the fluid in the well. Each of the sensor elements is provided with a base and sensors. The base is positionable on the coiled tubing system about the injection port. The sensors are positionable in the base. Each of the sensors are thermally isolated from each other, and are capable of operating as both a heater to heat the fluid, and as a temperature sensor for measuring a temperature of the fluid. The sensors are operatively interchangeable such that the sensors may selectively heat and measure the temperature of the fluid whereby fluid parameters of the fluid are determined.

摘要： A method for checking pipeline leakage comprises: receiving detecting parameters collected by at least one sensor with respect to pipelines in its corresponding region; gathering detecting parameters collected by the at least one sensor; analyzing the gathered detecting parameters to obtain an evolutionary tendency of detecting parameters in the corresponding region of the at least one sensor; judging if the evolutionary tendency of the detecting parameters satisfies predefined features of leakage; determining that pipeline leakage exists in the corresponding region if the evolutionary tendency of the detecting parameters satisfies the predefined features of leakage. The present invention may help to determine leak regions with a leakage having small flow quantity, and provide a user with regions with pipeline leakage to be detected based on a resource constraint.

摘要： A device is described for a system for conducting tests of a well, pipe or the like, where a plug of a removable material is inserted in a pipe through a well to carry out said tests. The device is characterised in that the wall parts of the pipe comprise channel borings (3,4,8) that set up fluid connections between the well space (70) and the well space (72) above and below, respectively, the plug, and that it comprises a closing body that can close the fluid connection permanently. The channel boring is preferably defined by an axial hollow space/chamber (4) in which a piston is arranged, said piston can be readjusted by an axial movement from a first position where there is fluid connection through the channel and a second position where the connection is permanently closed and can not be reopened.

摘要： Systems and methods for direct and indirect measurement of the density of a fluid which exhibits sag characteristics is disclosed. The sag measurement system (100) includes a test container (102) for holding a fluid mixture to be analyzed and a suction port (104) on the test container. A pump (108) is coupled to the suction port for circulating the fluid mixture from the test container through a circulation loop (110). A measurement device (112) is coupled to the circulation loop and a return port (106) directs the fluid mixture from the circulation loop back to the test container at substantially the same vertical location as the suction port. The fluid mixture flowing through the circulation loop passes through the measurement device before returning to the test container through the return port. The measurement device is operable to monitor the particle distribution of the fluid mixture as it changes due to gravity.
