Abstract
The invention discloses an oil gas testing parameter recorder and an operation state mode identification method and system. The oil gas testing parameter recorder based on tension change is provided with a tension suspension assembly, wherein at least one end of the tension suspension assembly is fixed, and at least one end of the tension suspension assembly is connected with an oil pipe to be lifted or a swab to be lifted; and a tension sensor is mounted at the fixed end of the tension suspension assembly. The operation state mode identification method comprises the following steps of collecting tension data by using the oil gas testing parameter recorder based on tension change, and identifying an operation state through a tension data time change curve, wherein the operation state comprises oil pipe unloading operation, oil pipe lifting operation and swabbing operation. The oil testing operation parameters can be effectively recorded, the operation state can be remotely monitored, the oil pumping amount can be monitored to a certain extent, and operation monitoring is realized.
Description
technical field [0001] The disclosure belongs to the field of oil and gas well detection, and in particular relates to an oil and gas test parameter recorder, an operation state pattern recognition method and a system. Background technique [0002] Oil (gas) testing is the key to achieving results in oil and gas exploration, the most direct means to find oil and gas fields and understand the underground conditions, and an important link to provide scientific basis for development. [0003] Specific process: After making preparations, the oil testers began to carry out "testing, exploration, and lifting" operations. "Testing" is pressure testing, testing the sealing performance of the wellhead Christmas tree and downhole casing; Wash the wellbore with clean water. Afterwards, oil testers will also participate in the logging and perforating operation, and drive the prepared special chemical solution downhole with a pump truck and send it to the well section to be perforated....
