Rotational viscometer low temperature test device

Abstract

The invention relates to an on-site drilling fluid viscosity test device under deepwater and low-temperature environment. The device comprises a composite refrigeration system, a heat insulation sleeve, a mud cup, an internal and external temperature sensor. During work, a to-be-tested sample is placed in the mud cup to be loaded into the refrigeration heat insulation sleeve together, the temperature is controlled by a control cabinet, according to the need, the temperature is set arbitrarily ranging from -10DEG C to 100DEG C, the power is switched on, and a refrigeration key is pressed to start work. A thermometer displays the temperature of a refrigeration body, and by pressing an internal and external temperature conversion key, the temperature of the sample in the cup can be observed and displayed, and test can be carried out when the temperature is constant. The device provided by the invention can satisfy drilling fluid low temperature performance test of deepwater drilling on-site operation.

Description

Technical field: [0001] The invention relates to an on-site drilling fluid viscosity testing device in a deep-water low-temperature environment. Background technique: [0002] The backwardness of domestic deepwater drilling fluid technology has become the main bottleneck in the development of deepwater resources. Different from land and shallow water areas, in deep water and low temperature environment, the viscosity of drilling fluid increases, the circulation pressure loss increases, and the pressure of liquid column increases, making well control more difficult. In order to provide reasonable low-temperature performance of drilling fluid for deep-water drilling field operations, a deep-water drilling fluid performance test device that can simulate low-temperature conditions on the seabed was developed. Invention content: [0003] The purpose of the present invention is a deep-water drilling fluid performance test device capable of simulating low temperature conditions ...
