نمایش نتیجه 1 تا 10 از 80 نتیجه یافت شده برای perforation:
the theoretical maximum flow that a well could deliver with a zero backpressure at the middle of the perforations.
a large, load supporting formation that may serve to reduce the total overburden load on a pay zone. These formations may cover hundreds of square miles over a basin. A second use is as a semi-stable structure of sand grains around a perforation or other
the flow area generated by perforations across a zone of interest. Typical calculated perforation entrance hole areas are 1% to 6% of the pipe body. Used in pressure drop calculations.
sudden backflow of a well, usually to clean the perforations.
n pi: balls made of nylon, hard rubber, or both and used to shut off perforations through which excessive fluid is being lost.
n: Made by nylon or ebonite. Used to block off the opening in the capital string and prevent fluid lossing when fracturing.
small, rubber-covered, hard centered balls that can seal individual perforations during a chemical treatment.
v: to plug open perforations by using ball sealers.
When using ball sealers, to effectively shut-off the entire zone and cause pressure to rise sharply.
n: casing without perforations.
n: a heavy wall sub placed in the tubing string opposite flowing perforations.
n: liner with no perforations. blank off v: to close off (as with a blank flange or bull plug).
