The invention discloses a thickening performance evaluation instrument for drilling plugging materials, which relates to the field of drilling exploration, and comprises a kettle body, a thickening motor, a heating component, an end test component, a top cover and a bottom cover; the upper and lower ends of the kettle body are both open Setting, the kettle body is set in the inner ring of the third bearing, the outer ring of the third bearing is connected with the first arm, and the first arm is used to limit the position of the kettle body; the kettle body is detachably connected with the thickening motor and is connected by The thickening motor drives the rotation. The thickening performance evaluation instrument can realize electric heating and air pressurization to simulate the underground environment, so that the obtained thickening time is closer to the actual thickening time, and it is convenient for relevant personnel to understand the actual thickening performance parameters of the plugging material.
Description
technical field [0001] The invention relates to the field of drilling exploration, in particular to a thickening performance evaluation instrument for drilling plugging materials. Background technique [0002] Lost circulation is one of the most troublesome drilling problems. Some well control problems may also result from increased economic costs due to the loss of expensive drilling fluids into the formation. The incidence of lost circulation in the world accounts for about 20% to 25% of the total number of wells, so lost circulation has always been a concern at home and abroad. Through scientific research, plugging materials represented by bridging, high water loss, and solidification have been developed at home and abroad, and a series of drilling fluid pressure plugging technologies have been formed. Compared with conventional plugging materials, curable plugging materials have higher pressure-bearing plugging capacity, easy control of curing time, low price, simple p...
