Sinopec News Network reported on August 9th, the exploration evaluation well Changtan 101 in the Binchang exploration area of the North China Oil and Gas branch achieved a breakthrough in gas production during the fracturing gas test of Well Box 2.
, The daily gas output is 18,274 cubic meters/day
.
The Binchang Exploration Area is a key exploration evaluation area for the Paleozoic of the southern Ordos Basin.
It presents the characteristics of "low porosity, low permeability, high Young's modulus, high Poisson's ratio, and high closure stress gradient".
, It is difficult to add sand during fracturing and sand plugging easily occurs
.
In view of the above difficulties, combined with the thin reservoir thickness of Changtan 101 Well, in order to ensure the success rate and post-fracturing effect of the fracturing operation of this well, optimization was carried out from the perspectives of fracturing scale, fracturing string, and reducing reservoir damage
.
Combining the logging display of the reservoir and the structural characteristics of the reservoir barrier, the sand addition strength is improved, and the design idea of large-scale long fracture fracturing is adopted to fully reform the reservoir
The successful implementation of Box 2 of Well Changtan 101 further confirmed that the Upper Paleozoic reservoirs in the Binchang exploration area have good gas-bearing properties and exploration prospects
