SYSTEMS AND METHODS FOR MONITORING DRILLING FLUID CONDITIONS

摘要

Systems and methods are provided for monitoring a well for unwanted formation fluid influx and unwanted drilling fluid losses during a period in which drilling operations are performed for the well. Systems include at least two transducers spaced apart along a bell nipple or riser of a well system at a position below a flow line. The transducers obtain pressure and temperature differentials and are electronically coupled to a transmitter that transmits the measurements to a computer. Methods include utilizing this data to determine properties of the fluid in the well and can be utilized for kick detection. The measurements can be taken in a continuous and real-time fashion.

1. A system for monitoring and detecting formation fluid influxes and drilling fluid losses in a well, the system comprising:
a blowout preventer stack; a bell nipple or marine riser coupled to the blowout preventer stack; a flow line coupled to a side of the bell nipple; a drill pipe extending through the bell nipple, the blowout preventer stack, and into the well, wherein fluid flows through the drill pipe into the well and returns through an annulus between the drill pipe and the bell nipple; a monitoring system coupled to the bell nipple or riser, the monitoring system comprising:
at least two transducers disposed on the bell nipple or riser and in contact with fluid flowing through the bell nipple or riser, wherein the at least two transducers are spaced a distance apart;a transmitter electronically coupled to the at least two transducers and configured to receive outputs from the at least two transducers; anda data receiving station in communication with the transmitter and configured to receive a data signal from the transmitter.
