"The casing subsidy has been successful.
It's great, and it doesn't leak at all
.
" On August 24, at the site of the Chun 10Ⅱ2-10-10HX1 well in the Chunguang Oilfield of Henan Oilfield, Cheng Hongxiao, an engineer in Henan Oilfield, was pleased.
The Chun 10Ⅱ2-10-10HX1 well is a thermal production horizontal well in the Chun 10 block of Henan Oilfield.
After the early leak detection construction, it was found that there was a conflict between the leakage point of the well section and the position of the casing coupling.
For this reason, the technical staff of the Academy of Engineering “Well” conditions, actively optimized the plan, improved tools, and implemented casing reinforcement subsidy technology, which achieved success
.
Since the beginning of this year, the situation of casing loss wells in Henan Oilfield has become more complicated.
Some wells have many casing loss points, and some wells have casing loss points that conflict with the casing coupling position, and some wells have serious sand production
.
For this reason, the technicians of the project team adopted different technical solutions for the different problems of a single well in accordance with the conditions of the "well", improved and perfected the tools, and ensured that the production requirements were met to the greatest extent
Since the beginning of this year, technicians from Henan Oilfield Engineering Institute have completed 6 wells and 8 missing well sections in the Chunguang Oilfield for casing reinforcement subsidy construction, all of which have been successful
.
After implementation, the casing subsidy section has a maximum temperature resistance of 354°C and a pressure resistance of 18 MPa.
