Fuel consumption testing device of rotary drilling rig and fuel consumption testing method

Abstract

The invention relates to the field of evaluation of energy consumption of rotary drilling rig, and particularly to an fuel consumption testing device of a rotary drilling rig and an fuel consumption testing method. The fuel consumption testing method includes full filling medium sands in a tested well, drilling in the tested well by a drill of a rotary drilling rig, and recording the test time t, the drilled depth h and the fuel consumption f; calculating the fuel consumption in unit time of the rotary drilling rig according to a function (G=kf / t) in the condition that the drilled depth h is a certain valve, wherein k is a correction coefficient and k is determined by a function (k=6 / h). The fuel consumption in unit time can be taken as a main index for evaluating the energy efficiency of the rotary drilling rig. In the fuel consumption testing method, the medium sands is used as the only drilling medium, the fuel consumption in unit time of a rotary drilling rig is calculated after the rotary drilling rig drills a certain depth. The fuel consumption testing device of the rotary drilling rig and the fuel consumption testing method provides consistent standard and mode of measurement of fuel consumption, different rotary drilling rigs can be conveniently compared horizontally.

Description

technical field [0001] The invention relates to the field of energy consumption evaluation of a rotary drilling rig, in particular to a fuel consumption testing device and a fuel consumption testing method of a rotary drilling rig. Background technique [0002] Energy conservation and emission reduction work is one of the country's long-term development strategic measures, and the task of promoting energy conservation and emission reduction of construction machinery is imminent. [0003] User surveys show that among the many factors that affect user purchases, fuel economy has become an indicator that most users focus on and consider. More and more users pay more attention to the direct cost of use, and the level of fuel consumption will directly affect the payback period of investment and profitability. [0004] Under the dual drive of market demand and technological innovation, many construction machinery enterprises have invested in the research and development of energy...

Problems solved by technology

However, due to the lack of scientific and unified construction machinery fuel consumption testing and evaluation standards in China, companies conduct research tests according to their own methods, and the fuel consumption and fuel saving rates announced by different companies are based on their own testing methods. The data from the data lack horizontal comparability
