Problems solved by technology
However, on the one hand, the existing test method needs to go directly to the actual drilling site for the test, and the implementation process is extremely risky and is not welcomed by the construction unit, so it is difficult to implement
On the other hand, although many drilling tests can be carried out by drilling a well for testing, the cost is high, and the rock mass cannot be replaced, so it is difficult to simulate the real drilling environment

The invention discloses a well drilling simulation test system, which comprises a rock cavity, a bottom hole assembly and a power device, wherein the rock cavity is used for placing drilled rock in awell drilling test; the bottom hole assembly is arranged in a BHA (bottom hole assembly) cavity and is used for carrying out drilling operation on the drilled rock; the BHA cavity communicates with the rock cavity; and the power device is connected with the bottom hole assembly and is used for providing driving force for the bottom hole assembly to regulate the operation state of the bottom hole assembly. According to the system, a miniature-edition actual-drilling test and real-time analysis can be carried out in a laboratory. Compared with the prior art, the system enables that the well drilling test does not need to be implemented in a well drilling field or does not need to be implemented by a physical test well, cost consumed by a field test is omitted, and the cost of a whole well drilling experiment is greatly lowered.
Description
technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to a drilling simulation test system. Background technique [0002] Drilling is a complex, difficult, and costly project, and it is often necessary to test and verify the effectiveness and rationality of drilling plans, tools, and materials. However, on the one hand, the existing test method needs to go directly to the actual drilling site for the test, which is extremely risky in the implementation process and is not welcomed by the construction unit, so it is difficult to implement. On the other hand, although many drilling tests can be carried out by drilling a well for testing, the cost is high, and the rock mass cannot be replaced, so it is difficult to simulate the real drilling environment. Contents of the invention [0003] In order to solve the above problems, the present invention provides a drilling simulation test system, said system co...
