Aoton Deep Shale Gas Drilling Test Integration Operation in Southwest China

ADD TO WISHLIST

Overview

Anton In the southwest region of the region, the oil drilling is fully refined and optimized, the optimization of advanced adaptation technology, the elaboration management and the operation mode of geological engineeringintegration, the comprehensive application of the solution, the rotary guide, the biosynthetic base drilling fluid, the elastic cement slurry, the rotating casing and so on, have formed the shale gas drilling technology template and created a number of record.

Talk with anton expert

1. Integrated geology-engineering program design, guide the construction ofthe whole project.
2.Customized biosynthetic based mud system and white oil based mudsystem.
3. Theoretical calculation and implementation of stratum bearing capacity.
4. Personalized bit design and drilling parameters matching.
5. Some standardized geosteering and horizontal well extensionoptimization
6. Refined project management and resource integration and organization.

It is suitable for deep shale gas drilling and testing integrated factory operation well pattern.

1. Shale gas drilling and completion technology/ultra-long horizontal well with a well depth of 5750m and a horizontal section of 3070m, reaching the "maximum oblique depth page" of petrochina.

2. The drilling cycle was 42 days, the integration of geology and engineering was carried out, and the optimal and fast drilling was achieved. The drilling rate of "double sweet target" was 100%, the average machine speed was6.6m/h, the cementing quality of horizontal section and productive section was 100%, and the quality rate was 97%.3. Well Yang 101H91-3, drilled by the 70002 drilling team of TongshengDrilling Group of Andong Petroleum, refreshed the deep shale gas in Luzhou block of petrochina.
