【Abstract】 The changes in the drilling fluid viscosity affect the intrusion of drilling fluid in a well and the diffusion of oil-gas water in the formation, thus influencing the production capability assessment on gas-oil reservoir. The drilling fluid viscosity has been obtained from the detection of the liquid level of drilling fluid, which is implemented by the newly-developed detecting meter of drilling fluid viscosity. This approach can raise the detecting accuracy of drilling fluid viscosity, and meanwhile can be used by combining with integrated logging instrument, thus providing reliable information for logging material correction and improvement of explanation and assessment on site oil-gas formation.更多还原
