A coiled piece of tubing is usually referred to as a “loop”, “coil” or “reactor” in this context. The fact that the diameter of a coil influences dispersion inside it has been used to develop the so-called “knotted reactors”. Figure 1.46 shows three typical tubing configurations, ...
In the horizontal portion of a borehole, the use of coiled tubing has proven successful in "pushing" the logging instrumentation toward the bottom (end) of the borehole. The basic concepts, considerations, observations, and field experiences with this technology are discussed and illustrated in ...
Introduction The production and transportation of petroleum from subsurface reservoirs to end-users are accomplished with circular pipes, which include production tubings, pipelines similar process vessels (Mansoori et al. 2017; Nejad and Karimi 2017). However, it is not unusual for these conduits an...
METHOD AND DEVICE FOR PRODUCING A COILED TUBING FROM A THERMOPLASTIC MATERIAL In a method for producing a coiled tubing (RW) from a thermoplastic material, in a first shaping step a tubular extrudate (EX) is extruded via an annular n... M Holst,I Steitz 被引量: 0发表: 2022年 Composite...
The designed PspA1-5c+p protein is predicted to be highly antigenic, non-toxic, soluble, stable with low flexibility in MD simulation, and able to stimulate both humoral and cellular immune responses. The designed protein also could interact strongly with HLADRB1*(01:01) and human lactoferrin...
Fertility in birds is dependent on their ability to store adequate populations of viable sperm for extended durations in sperm storage tubules (SSTs). The exact mechanisms by which sperm enter, reside, and egress from the SSTs are still controversial. Sh
Introduction Satellite-based remote sensing data suggest that annual pelagic net primary production in shelf areas of the Arctic Ocean has increased by 20% from 1998 to 2009, mainly due to the longer seasonal duration of the ice-free period, and thus a longer pelagic growth season1. The contri...
An integrated circuit type device having a series of bond pads for the interconnection of the device with external power or communication lines, a method of improving the registration accuracy of the
1 Introduction The natural flowing wells are characterized by a high reservoir pressure, in which the fluids contained in their interior reach the surface freely. That is, the flow of fluids - oil, water and gas - from the reservoir to the facilities is due only to the reservoir energy, wh...
