Carry out stability and load calculations. 做稳性和载荷计算 185. Pass pendant line, shackle and buoy to anchor handling vessel. 将起抛锚短索, 卸扣和浮标吊起给起锚船 186. Lower the windward anchor to seafloor. 抛 27、上风锚到海底 187. Pick up the leeward anchor first. 先起下风锚 188. ...
granular and cohesive soils. The authors conducted a statistical analysis of the collected data to develop a relationship between the settlement trough and the depth of the piping. The equations were proposed for circular tunneling pipes; as such, it is applicable for HDD settlement calculations. ...
In this study, non Newtonian turbulent flow simulation was obtained through a drill bit to show the effect of flow rate, drilling mud density, and nozzle size on the tri-cone bit pressure drop calculations. Nozzle sizes of 7/32, 9/32, 10/32, and 11/32 inch were selected, and three ...
This study presents the concept of shaft constructed by raise boring in underground mines, and the idea of inverse construction can be extended to other fields of underground engineering. The conventional raise boring methods, such as the wood support method, the hanging cage method, the creeping ...
The attrition calculations for barite and delaminated iron ores were illustrated in Table 4 based on the relation between grains size and shear time to determine the physical performance of these grains. From the tabulated data in Table 4 it was speculated that the delaminated iron ore (hematite-...
prefer the use of a computer to perform the calculations and have, therefor, prepared a suitable program to be executed by computer to calculate the value of the circulating volume, V, of the drilling fluid. The particular computer program employed by Applicants forms no part of this invention...
our calculations, in deep wells the deformable element in this type of tool will have lost any shock absorbing capability it had by the time that the tool is at total depth, even before drilling commences. For example, if one were to consider a 12,000 foot deep well bore containing a ...
In the process, calculations are made to determine the appropriate thickness of each layer of the tool prior to the manufacturing of the tool. The container is then divided into compartments according to the calculations for each layer. Powdered metal is then added to the container in the ...
