About How effective is the Lishui rock drill
By comparing the other studies, we believe that the combination of geophysics with sedimentary facies is an effective method for the determination of source rock thickness in the East China Sea Shelf Basin. This method can be extended to other basins lacking boreholes.

The Lishui Sag, located in the East China Sea shelf basin, is one of the most promising offshore oil and gas exploration areas in China. Drillings in recent years have yielded unsatisfactory results. Characterizing source rocks in oil and gas exploration in the whole study area can help to find.
Lishui Sag, a sag with great exploration potential in the East China Sea Basin, has a low degree of exploration and few drilling results in recent years, so it is urgent to comprehensively evaluate its source rocks. Comprehensive evaluation of source rocks in Lishui Sag was carried out based on the.
The results show that the seismic reflection of source rocks in this area is characterized by low frequency and high amplitude. And source rocks mainly distribute in the Yueguifeng and Lingfeng Formation, characterized by a high percentage of mudstone. Source rocks in the East Subsag and South.
Rotary Drilling involves the use of a rotary drill rig that applies both shaft pressure and rotary torque to drive the drill bit into the rock. The bit’s rotation combined with applied pressure generates static and dynamic impact forces that fracture the rock. This method is versatile and.

6 FAQs about [How effective is the Lishui rock drill ]
Is Lishui sag a promising oil & gas exploration area?
The Lishui Sag, located in the East China Sea shelf basin, is one of the most promising offshore oil and gas exploration areas in China. Drillings in recent years have yielded unsatisfactory results. Characterizing source rocks in oil and gas exploration in the whole study area can help to find targets that may contain oil.
Do we know the source rocks in the Lishui SAG?
However, the knowledge of source rocks is limited to a few locations of previous drillings. Therefore, we proposed integrating borehole (sedimentary facies) and seismic data to determine the location and thickness of the source rocks in the Lishui Sag, China.
What is the thickest layer in Lishui SAG?
For the target layer, the upper Lingfeng Formation (Fig. 6 A), the thickness of source rocks in the Lishui Sag near well W2 is the thickest of the area, reaching 500 m, and the source rocks are in the smaller range of East Subsag and South Subsag, where the thickness is less than 200 m (Fig. 6 A).
Where is Lishui SAG located?
The Lishui Sag is located in the southwestern part of the East China Sea Shelf Basin and is generally distributed in the NW direction. Its north is adjacent to the Qiantang Sag (Zhang et al. 2015). Its east is separated by the Yandang Ridge (Xu 2020).
What is the area of 3D seismic data in Lishui SAG?
The area of the 3D seismic data is 2468 km 2, accounting for 17.9% of the Lishui Sag. The bin spacing is 25 m * 25 m, and the sampling interval is 2 ms. The years of 3D seismic exploration are 1998 (256 km 2), 2006 (481 km 2), 2008 (318 km 2), 2014 (658 km 2), and 2015 (1067 km 2).
Can interpolation predict oilfield development in the Lishui depression?
However, for the vast expanse of the Lishui Depression covering an area of 14,600 km 2, such an interpolation method exhibits inadequate precision and can only serve as a general research reference. Employing such predictive outcomes in guiding practical oilfield development is inappropriate.
