Henan Oilfield Exploration Well Chun 316 Well Obtained Industrial Airflow

News from Sinopec News Network On August 8, good news came from the Chunguang exploration area.
Following the industrial oil flow in the Chunguang 314 well, the Chun 316 well tested industrial gas flow in the Paleogene, with a daily output of 12,236 cubic meters of natural gas
.

From 2019 to 2020, after the Paleogene Chun 130, Chun 308 and other wells tested the industrial oil and gas flow, the researchers of the Chunguang Project Group of the Exploration Research Institute of Henan Oilfield Research Institute deepened the sedimentary research, and the Paleogene underwater distributary channel Reformed channels and beach-bar lithological traps are key areas for research.
However, the Paleogene oil and gas show that there are many reservoir-forming wells and the unclear main controlling factors of reservoir-forming have always been "blockers" that stand in front of scientific researchers
.

To this end, the researchers carried out retrospective evaluations of well-drilled wells, and carried out in-depth research on the accumulation conditions of the Paleogene, and finally clarified the favorable microfacies belt, the transportation conditions and the roof and floor conditions to control the development and accumulation of traps.
According to the two main small layers, four favorable reservoir-forming areas were selected, and geophysical exploration technology was carried out under the guidance of sedimentary microfacies.
Through forward and inversion, combined with line drawing technology, a number of trap targets were portrayed and deployed in the Paleogene.

Well Chun 316 is located to the east of Well Chun 116E, and the purpose is to drill the hydrocarbon-bearing nature of Paleogene lithological traps in the southwest of Chunguang exploration area
.

The well began to test the target layer on July 30, and discharged on August 7.
The daily gas production was 12,236 cubic meters, the condensate oil was 0.
07 cubic meters, the oil pressure was 12.
0-11.
8 MPa, and the casing pressure was 14.
5 MPa
.

　　It is reported that before the well obtained the industrial air flow, for the glutenite reservoir in the southwestern Cretaceous Chun 139 well area, scientific researchers used the fine description of sedimentary microfacies and prediction technology to tackle key problems.
The deployment of drilling Chun 314 well tested a daily output of 5.
16 in July.
The cubic meter of industrial oil flow has confirmed the exploration potential of glutenite and formed a new field for increasing reserves
.

　　Following the acquisition of industrial oil flow from Well Chun 314 in the Cretaceous, Well Chun 316 again tested industrial gas flow in the Paleogene, which made an important contribution to the increase in reserves and production of the Chunguang Oilfield, and it also strengthened the research and research personnel in the new formation of the Chunguang exploration area.
