摘要： The present invention addresses to the use of a viscous fluid in continuous pumping to contain the saline dissolution in a homogeneous way (not limited to just one type of evaporite), highlighting the results of seawater with viscosifiers, due to its simplicity, and that does not have the same impact on the logistical chain as a brine supply. The increase in fluid viscosity limits the diffusion of salt into the medium and thus better contains the dissolution of the well walls, while also promoting a laminar flow regime in the annulus of the well, variables desired to achieve the quality of the operation of cementation. The employment of viscous fluid concentrates allows “on the fly” dilutions with the in-line seawater fraction mixture. The technique can also employ solutions of pre-dispersed viscosifying additives which, when added to seawater, result in a substantial increase in the volume of drilling fluid produced, no longer limited by the unit tank capacity. This allows drilling large extensions of salt. The low salinity viscous fluid is used in drilling operations without fluid return to the drilling rig (riserless) in the presence of a predominantly saline formation, aiming at preserving the phase diameter and improve well construction conditions.

摘要： The disclosure concerns oil drilling technology, and specifically an all-metal intelligent control motor (AMIM). The AMIM comprises an electric control module, a power module and a transmission module. The electric control module determines the axial position of the connecting rod valve through an electromagnet and controls the connection between the connecting rod valve and the piston through an electric motor. The hydraulic pressure of drilling fluid and the spring reaction force in the power module push a double worm to move axially and circumferentially under the action of internal teeth on the inner surface of shell. A one-way bearing ensures that the power module only transmits unidirectional motion. The transmission module axially limits the power module through TC bearings and transmits circumferential motion, drilling pressure and torque to the lower drilling tool. The AMIM is suitable for all kinds of deep well exploration, with a stronger drilling force, a lower cost and a higher applicability.

摘要： Methods, systems, and techniques for detecting at least one of an influx event and a loss event during well drilling involve using one or both of errors between 1) estimated and measured pit volume, and 2) estimated and measured flow out, to identify or determine whether the influx or loss event is occurring, or to sound some other type of related alert. These determinations may be performed in a computationally efficient manner, such as by using one or both of a time and depth sensitive regression.

摘要： A technique facilitates a drilling operation, e.g. a land-based drilling operation, by enabling a substantial reduction in the number of equipment components. According to an embodiment, a mud pump assembly is provided with at least one mud pump located on a rig positioned at a wellsite. The mud pumps may be run to perform a mud pumping operation by pumping mud downhole during drilling of a borehole, e.g. a wellbore. During stoppage of the mud pumping operation, the same mud pumps are utilized to perform a cementing operation in which cementing fluid is pumped downhole for cementing of casing. The use of the same mud pumps enables the operator to eliminate not only the separate cement pumps otherwise used for the cementing operation but also the motive units that would be associated with those separate cement pumps.

摘要： Processes for injection of fluids into a wellbore via drill pipe. In some embodiments, the process can include positioning a downhole apparatus on a drill pipe. The process can also include placing the downhole apparatus at a desired station depth within a wellbore. The process can also include attaching a cable to the downhole apparatus from an up-hole environment. The process can also include setting at least one packer to seal a space between at least a portion of the downhole apparatus and an inner surface of the wellbore. The process can also include introducing a fluid to the downhole apparatus through the drill pipe. The process can also include using a pump from the downhole apparatus or a pump located at a surface of the earth to inject at least a portion of the fluid from the downhole apparatus into a geological stratum at the desired station depth.

摘要： A system and method for a fully-integrated flow control module (FI-FCM) in a hydrocarbon reservoir is disclosed. The FI-FCM is a unibody structure or a single-piece machined body having a flow meter integrated to the unibody structure. A choke is to be associated within a provision of the FI-FCM that also has an entry flow path for reservoir fluid and an exit flow path for the reservoir fluid. The entry flow path and the exit flow path inside the unibody structure or the single-piece machined body. Fluid communication is enabled between the flow meter, which is upstream relative to the choke, and an entry flow path. The choke is to control flow between the entry flow path and the exit flow path.

摘要： Testing a fluid in a wellbore with a well testing tool carried on a well testing string includes activating a first selectively controllable longitudinal valve and a second selectively controllable longitudinal valve with a communication module. A first and second packer of the well testing tool engages an inner wall of the wellbore to define a zone of interest between the first packer and the second packer. The communication module further activates a selectively controllable radial valve positioned between the first packer and the second packer to flow fluid between the central bore and the annulus formed between the first packer and the second packer, a fluid sample flows from the annulus between the first packer and the second packer through the testing string to a tophole facility.
