Description

Technical Field

[0001] The invention belongs to the technical field of oil field control equipment, and in particular relates to a wireless remote control intelligent recording system for a drilling pressure test pump. Background Art

[0002] Well control is an extremely important part of drilling operations, and hydraulic well plugs are key equipment in well control. When a well control hazard occurs, high-pressure hydraulic oil is needed to push the piston in the hydraulic well plug to achieve the purpose of shutting in the well, and the hydraulic well plug must be able to completely seal the underground space after shutting in the well, otherwise the consequences will be disastrous if a well control hazard occurs.

[0003] The pressure test pump consists of a water tank, a reciprocating plunger pump, a motor, and a pressure relief valve. Its function is to inject high-pressure water into the hydraulic well sealer, high-pressure manifold or casing after the hydraulic well sealer is installed. By observing and calculating the pressure drop over a period of time, it is judged whether the hydraulic well sealer can completely block the underground space after the well is shut in. The specific method is to connect the inlet of the reciprocating plunger pump to the water tank and the outlet to the pressure test space of the hydraulic well sealer through the high-pressure manifold, and then use the motor to drive the reciprocating plunger pump to work, so that the water in the water tank generates a certain pressure, and then inject high-pressure water into the hydraulic well sealer, high-pressure manifold or casing for pressure test. By observing and calculating the pressure drop in the high-pressure manifold over a period of time, it is judged whether the hydraulic well sealer can completely block the underground space after the well is shut in. After the pressure test is completed, the pressure relief valve installed on the high-pressure manifold is opened to release the high-pressure water in the high-pressure manifold.

[0004] However, at present, the start and stop control of the pressure test pump is realized locally through the start and stop switch. After the pressure test is completed, the opening and closing of the pressure relief valve is also realized by operating the pressure relief valve handle locally. However, in the actual pressure test process, the pressure generally reaches more than 10MPa, and the highest even exceeds 100MPa. Obviously, it is very dangerous to start and stop the pressure test pump and switch the pressure relief valve locally under such high pressure.

[0005] In addition, the current recording of pressure test data is generally achieved by using a finished paperless recorder, which only has the function of continuously collecting and storing pressure data, and does not have the function of intelligently judging whether the pressure test is qualified during the on-site pressure test. In order to judge whether the pressure test is qualified, it is required that during the pressure test, the on-site operator manually records the pressure data continuously, and judges whether the pressure test is qualified by combining the pump stop pressure holding time and pressure drop. The role of the paperless recorder is only to print the relevant pressure holding curve for future reference based on the time point recorded by the operator. Summary of the invention

Then press the pressure test pump start button, and the local controller 1-1 will control the pressure test pump start and stop controller 1-5 to be energized, thereby closing the motor contactor of the pressure test pump to realize the operation of the pressure test pump. At the same time, the auxiliary contact signal of the motor contactor is fed back to the local controller 1-1.

At this time, the remote control and pressure test data intelligent recording and judgment device first sends a pump start instruction to remotely control the start of the pressure test pump, and also sends the "pressure upper limit" to the pressure acquisition and pressure test pump pressure relief valve output control device; after receiving the instruction, the pressure acquisition and pressure test pump pressure relief valve output control device immediately controls the start of the pressure test pump, and uses the pressure sensor 1-3 to automatically collect and process the pressure test data at an interval of 20ms, and sends the pressure test data and the working status of the pressure test pump through the local wireless communication module 1-4 at an interval of 1 second, and once it is detected that the pressure test reaches the " When the pressure test pump stops, the remote main controller 2-1 on the remote control and pressure test data intelligent recording and judgment device will immediately start the data acquisition and judgment program after finding that the pressure test pump has stopped, and use the SD card 2-6 to record the current pressure test pressure and time.
