Problems solved by technology

[0002] In recent years, with the extensive use of new technologies and processes in the development of oil and gas wells, wellhead snubbing operations have become more and more common. Due to technological requirements, the diameter and combined length of the blowout preventer in the well control equipment have increased, making the well The volume of the well control equipment increases, and the pressure test of the well control equipment before the pressure operation becomes a problem: the traditional pressure test pump cannot be used due to its small displacement and rated pressure, and only large-scale equipment is used------- Vehicle-mounted high-pressure water injection pump truck (cement truck), there must be a cement truck waiting at the well site for each construction, and the investment of large equipment will increase the cost

[0004] The special "cement truck" is a large-scale equipment, and the cost required for each dispatch is not low, and the cost of use is relatively high; the "cement truck" needs to be connected with the workpiece to be tested with a hard pipe, and the diameter of the pipe is large, so the connection is very inconvenient And it takes a lot of time for on-site workers; the booster pump of the "cement truck" has a low displacement. When testing large-diameter blowout preventers and blowout preventers, it takes a very long time to test. Seriously affected the mining progress; the "cement truck" can only observe the pressure intensity through a built-in pressure indicator. If it is necessary to adjust the internal pressure of the workpiece under test, workers need to make subjective judgments based on the pressure indicator and their own experience. Re-adjustment, the accuracy is low; the pressure display observation accuracy is low, and the pressure test results cannot be stored and recorded
