The invention relates to the technical field of testing devices, and provides a coiled tubing horizontal well testing device. The device comprises a ground signal receiving device, coiled tubing, a flexible pup joint, a telemetry pup joint, a tension pup joint, a releasing tool and a testing device; the flexible pup joint, the telemetry pup joint, the tension pup joint, the releasing tool and the testing device are fixedly installed together in sequence from left to right. The coiled tubing horizontal well testing device is reasonable and compact in structure and convenient to use; due to the fact that the ground signal receiving device, the coiled tubing, the flexible pup joint, the telemetry pup joint, the tension pup joint, the releasing tool and the testing device are used together, a horizontal well casing test, a horizontal well segmented fluid production test and a formation pressure recovery test are achieved, test data is transmitted to the ground in real time, real and accurate dynamic monitoring data is provided for oil field horizontal well development, the device has the advantages of being safe and reliable, operation is convenient, the working efficiency is improved, and the device is applied to oil well horizontal section tests.
Description
technical field [0001] The invention relates to the technical field of testing devices, and relates to a coiled tubing horizontal well testing device. Background technique [0002] Horizontal well development technology has developed rapidly in the world in recent years, and has been applied to almost all types of oil and gas reservoirs. With the increasing maturity of various technologies, the number of horizontal wells is increasing year by year. Horizontal well testing technology is an important supporting technology for horizontal well development. . Conventional wireline well testing technology is no longer suitable for testing the horizontal section of oil wells. Contents of the invention [0003] The invention provides a coiled tubing horizontal well testing device, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem that the conventional cable well testing technology cannot be applied to the testing of the horiz...
