powering a downhole pump and a rate change is required 当发动机驱 动的大泵排量需要变化时将导致混配能量的改变。 HT-400 • Positive displacement • Single acting- triplex pump • Up to 20,000 psi of pumping pressure • Up to 19 bbl/min. ...
centrifugal pump 20 and input to a positive displacement down hole pump 22 such as a Halliburton Services HT-400 Model triplex piston pump, or the like. Optical probe 10 includes optical switch means 24 (FIG. 5), such as a photoresistor, or the like and a circuit card 25 including a ...
Equipment which may be required to accomplish this includes: dual Halliburton Services HT-400 RCM pump truck (4.7 bpm at 5000 psi); 1400 cu. ft. bulk cement storage bin; drilling mud desander/desilter unit; office/decontamination trailer; 60 ton crane; 100 foot long jetting beam (19000 lbs...
One such case is the thread on cover retainers used on plunger pumps such as the Halliburton Model HT-400. The cover retainers are used to retain valves and rupture discs in the fluid end of the pump, and the diameter of the thread is relatively large compared to the length of thread en...
The preferred embodiment of the present invention shown in FIGS. 2-6 is contemplated to be used with a specific composition of pumping, blending and cementing equipment used on offshore platforms. This specific composition includes five HT-400 electrically driven pump skids, one fifty-barrel electri...
divided mixing tub202in combination with a break point look-up table. The controller126may further control the mixture supply pump118to control the outflow of the mixture. The process400proceeds from block424back to block408, suggesting the repetitive and/or iterative nature of the controlling ...
22. A system comprising: a drilling assembly with a drill string extending therefrom and into a wellbore in a subterranean formation with at least one depleted zone having a plurality of fractures extending from the wellbore into the at least one depleted zone; and a pump fluidly coupled to ...
11.The method of claim 1, wherein prior to the step of introducing, the method further comprises mixing the treatment fluid in a mixer, wherein the introducing comprises pumping the treatment fluid into the wellbore with a pump. 12.The method of claim 1, wherein the composite diverting part...
A hose for a reciprocating pump, the hose comprising: a first end and a second end separated by a length (L) along a centerline of the hose, wherein the first end reciprocates with
“Worm Pump For Flowable Media,” utilizes a stator wall composed of a rubber with a Shore A hardness of 90 to 95 (tested in accordance with ASTM D2240). Such a hard elastomer property is desirable for withstanding the abrasive wear found in conventional down hole drilling motors. However,...
