Systematic testing methods of the performance of diamond/metal composite drilling segments (impregnated diamond cutters) have not come into being. This article tries to test the mechanical properties, structures and component of a certain number of impregnated diamond cutters; focuses on analysis of the relationship between the performance of typical composite diamond cutters and materials’ structures, intends to study the testing methods of impregnated diamond cutters’ performance.

The present work deals with temperature effects and parametric optimization in the drilling of continuous glass fiber reinforced epoxy composite. Drilling ability was examined operating a drilling system with different drill bits, feed rate, and spindle speed parameters. The investigation was performed by changing the tool and composite interface. Drilling experiments were carried out under the dry condition. Thrust force and drilling temperatures were measured using dynamometer and thermal camera. Peel-up and push-out delamination were evaluated using an image analyzing tool. Results show that the tribo-mechanical behavior of the drilling operation is affected at different levels by tool coating. This behavior is related to the intrinsic friction properties of coating nature. Response surface methodology was used in the evaluation of experiment results. The feed rate of 0.13 mm/rev, spindle speed of 2425 rpm and HSS-TiN drill bit are found as an optimum drilling parameters and drill type.

Composite Drilling

A drilling riser joint with carbon fibre in the main structural body and titanium end flanges was put into service at the Heidrun TLP in 2001. The joint has an internal titanium liner. The joint was the first implementation of an offshore composite riser and was the end result of the Compriser project. The composite riser joint has an internal diameter of 560 mm (22”) and is 15 m (48 ft) long. The joint is a part of the marine riser. The joint has been in service for ten years and has been treated as its metallic counterparts. At the periodic inspection done in 2010, it was decided that the external layer needed refurbishment. Inspection and pressure testing showed that the properties of the joint had not changed during service.

With the depletion of shallow-layer oil and gas pools inLiaohe oilfield, buried hill stratigraphic reservoirs in Liaohe oil field are becoming main objectives for exploration in recent years, especially in high-risk areas of Xinglongtai deep the Hing ancient buried hill resources are particularly rich. Since 2007, Liaohe oilfield increased investment for Buried Hill reservoirs with deep horizontal drilling developt the buried hill reservoir. Liaohe has completed 36 deep horizontal, with a total footage of 183920m, the average depth of 5109m. Improving drilling speed of "buried hill deep horizontal and branch horizontal wells”, and reducing drilling costs are of great urgency. “Hing buried hill deep horizontal, horizontal wells,” with composite drilling technology, supporting the optimization of PDC bits, the high-pressure jet drilling, the MWD borehole trajectory control and optimization of drilling parameters, the new drilling fluid technology and so on. With a large number of horizontal wells put into Buried Hill stratigraphic reservoirs, oil and gas production of average deep horizontal well increase of 2-5 times. Besides, the previous recovery and production of oil and gas reservoirs significantly improved to create an objective economic and social benefits.

Composite Drilling

The present work deals with the finite element simulation of drilling of fibre-reinforced composites. The simulation is done using commercially available software. Hashin failure criteria has been used to simulate the drilling process. Three dimensional drill model was created and Hashin failure is defined via VUMAT sub-routine. Three-dimensional Hashin failure have larger stress and strain analysis resolution. This research is focused on validating reaction force and accuracy of drill. Reaction force obtained in composite drilling simulation is compared with experimental data. The work is focused on reproducing the simulation of composite modelling and composite damage rather than theoretical explanation of composite material and mathematical model behind the simulation. Thus, laying the knowledge to simulate composite fibres failure.
