AI Technical Summary
In existing oilfield stratified water injection technology, the pressure testing process is cumbersome, the number of times the plugging electronic pressure gauges and plugs need to be deployed and retrieved is large, the operation time is long, the success rate is low, there is a risk of well sticking, the labor intensity is high, and the cost is high.
The device employs a convenient and efficient stratified pressure measurement system for oilfield water injection, including a sealed section and a plug-type electronic pressure gauge. Through the delivery, unsealing, pressure bearing, setting, and locking mechanisms, it enables simultaneous measurement of pressure changes in the upper and lower sections of the dual-channel eccentric water distributor in a single well run, reducing operational steps and the occurrence of equipment jamming.
It improved the success rate of pressure testing, reduced operation time and costs, reduced labor intensity, saved on well test vehicle operating losses and fuel consumption, improved employee efficiency, and reduced unit operating costs, resulting in significant economic and social benefits.
