Description

Intelligent alarm device for drilling overflow

Technical Field

The utility model belongs to the technical field of thing networking data processing equipment, concretely relates to be applied to well drilling overflow intelligent alarm device of oil field well drilling field data.

Background

In the drilling process, overflow is inevitable, and means that when the formation pressure of the drilled well is greater than the bottom pressure, the formation pressure forces formation fluid to enter the well, so that the drilling fluid amount returned from the well mouth is greater than the pumping amount, and the drilling fluid at the well mouth automatically overflows after the pump is stopped. The severity of the flooding depends primarily on the porosity, permeability, and magnitude of the differential negative pressure of the formation. The higher the porosity and permeability of the formation, the larger the negative pressure difference, and the more severe the flooding. The overflow is a precursor of the kick and the blowout, and the serious damage caused by the kick or the blowout can be avoided by finding the overflow as soon as possible, so that the safety of personnel and equipment is guaranteed. Especially, the early detection of small overflow amount in the deep well drilling process is very important, because the bottom pressure of the deep well is high, and a small amount of gas entering the well expands into a large amount of gas when being transported to a wellhead.

In the prior art, the overflow of the drilling well is monitored by monitoring the height change of the liquid level of the mud tank, but the conventional mud tank has a large inner sectional area, and when the overflow amount is small, the liquid level of the mud tank rises very slightly, so that the prior art cannot accurately find the trace overflow. And the fluctuation of the liquid level of the mud tank, cleaning equipment or water adding into the mud tank and the like can cause the liquid level to rise or fall, so that the monitoring of the mud tank liquid level monitoring device has errors. Therefore, the tiny overflow is difficult to find by monitoring the liquid level of the mud tank at present, and the calculation is needed when the overflow is detected or not, so that the detection is very inconvenient, and the time for finding the overflow and the overflow is delayed.
