Technical Field

[0001] This utility model relates to the field of drilling fluid testing technology, specifically a novel drilling fluid testing instrument. Background Technology

[0002] Drilling fluid testing plays a crucial role in several aspects. First, by testing the performance parameters of drilling fluids, such as density and viscosity, it is possible to effectively control well pressure, prevent accidents such as blowouts or lost circulation, and ensure the safety of drilling operations. Second, testing helps to understand the impact of drilling fluids on the formation, avoiding damage to oil and gas reservoirs and protecting them. Third, the test results can be used to optimize drilling fluid formulations, improve drilling efficiency, and reduce costs. In short, drilling fluid testing is a key link in ensuring the smooth progress of drilling projects, protecting oil and gas reservoirs, and improving economic benefits.

This device includes a shell, and inside the shell, a drainage unit, a sampling box, a pressurization unit, and a testing device. The sampling box is a closed hollow shell with a sampling hole on its bottom plate. The testing device is located below the sampling hole, with its probe end positioned inside the sampling box from the sampling hole. The pressurization unit consists of a sampling tube, a pressurization pump, and a pressure pipe. Both ends of the sampling tube are connected to the outside environment and the sampling box, respectively. The sampling tube also has a branch pipe connected to the pressure pipe, the other end of which is connected to the pressurization pump. The drainage unit consists of an outlet pipe located at the bottom of the sampling box and an oil pump. Both ends of the outlet pipe are connected to the oil pump and the outside environment, respectively. This drilling fluid testing device has a reasonable structural design, is simple to operate, and easy to clean. It can achieve quantitative extraction, information collection, and information transmission of drilling fluid, reducing the difficulty of testing work. It can also perform batch testing of drilling fluids at multiple construction sites.

[0004] Drilling fluid is extracted manually, and its properties such as fluidity and viscosity need to be tested step by step after extraction. This step-by-step testing results in low detection efficiency of drilling fluid. Therefore, those skilled in the art have provided a new type of drilling fluid testing instrument to solve the problems mentioned in the background art. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This novel drilling fluid testing instrument uses a liquid funnel to hold the drilling fluid through a transport pipe. The liquid funnel slowly discharges the drilling fluid through a conical funnel at its bottom. A flow rate detector is located at the lower left of the liquid funnel to detect the discharge rate of the drilling fluid, allowing operators to observe the fluidity and viscosity of the drilling fluid in real time. The bottom funnel of the liquid funnel is located above the rear end of the solution container, allowing the discharged drilling fluid to be directly placed inside for further testing. This improves the efficiency and speed of drilling fluid testing and avoids the tediousness of manual step-by-step testing.

Inside the isolation plate is a measuring component connected to a viscosity tester. The measuring component is a six-speed rotary viscometer device, which can directly test the rheological properties of the drilling fluid. This design allows the drilling fluid to be tested in an assembly line manner, making the testing process highly continuous and significantly reducing the time wasted during the transfer of drilling fluid.
