Abstract:

HZM bi-fuel system can substitute the diesel fuel by controlling the gas which enters the diesel engine,but the gas
does not participate in the speed control,and the system requires no major changes or modifications. The introduction of HZM
bi-fuel system used in deep well drilling at Tarim Oilfield is one of the best ways to reduce cost and protect environment. Field
application shows that diesel engine has good economic benefit when the diesel substituting rate is 40% and running under the
rated power of 30%~80%. Employment and suitability test researching the improvement of these two kinds of power package,
performance of bi-fuel system,effect of bi-fuel operation on the unit,indicate that bi-fuel system can meet all the drilling
conditions. During the last two years,HZM bi-fuel system has been applied by 9 drilling crews in 14 wells has consumed
about 301×104 m3 natural gas. HZM bi-fuel system is highly worth popularizing because of its economic benefit,safety and
reliability.

Key words: HZM bi-fuel system, deep drilling rig, power package retrofit, employment and suitability test
